How to Bill Carrot Fertility Patients: A Complete Practice Guide

Carrot Fertility is an employer-sponsored fertility benefits platform that serves as a spending account and reimbursement system, not a health insurance payer. When a fertility practice receives a patient who identifies Carrot as their fertility benefit, the billing pathway diverges entirely from the standard insurance workflow — there is no payer ID to submit to, no prior authorization queue to manage through Carrot's adjudication system, and no ERA to post. The practice's financial relationship for Carrot members runs primarily through the patient, not through Carrot as a third-party payer. Practices that attempt to route Carrot patients through their standard insurance billing workflow will encounter systematic confusion: Carrot will not appear in any clearinghouse payer directory because Carrot is not a health insurer, the patient will not have a traditional insurance card with group and member ID numbers that map to an insurance plan, and there is no claims adjudication outcome to receive in 30 days. Understanding Carrot's structure before the first Carrot patient walks through the door is not optional — it determines whether the practice collects correctly or loses revenue to workflow failures that are structurally preventable.

What Carrot Fertility Is — And What It Is Not

Carrot Fertility is a digital fertility benefits administration platform. Employers that contract with Carrot fund a fertility benefit wallet for their employees — a defined dollar amount per benefit year or as a lifetime maximum — which employees access through the Carrot platform. The benefit wallet funds a range of fertility and family-building services defined by the employer: IVF, IUI, egg freezing, embryo banking, PGT, donor egg and sperm services, gestational carrier arrangements, adoption, and in some employer plans fertility preservation for gender-affirming care. The specific services covered and the dollar amount available are entirely employer-defined — Carrot itself provides the platform and the administrative infrastructure; the employer defines the benefit scope. Carrot is not licensed as a health insurance company. It does not process insurance claims under state insurance department jurisdiction, does not issue Explanations of Benefits in the regulatory sense, and does not have contractual obligations to pay provider claims under state insurance codes. From a billing operations standpoint, the critical distinction is this: Carrot members are not insurance patients. They are patients with employer-funded spending accounts, and the financial transaction between the practice and the patient is effectively a self-pay transaction that the patient funds entirely or partially using their Carrot benefit.

How Carrot Patients Pay: The Three Billing Pathways

Carrot members access their fertility benefit through one of three pathways, and understanding which pathway applies to a given patient determines how the practice structures its financial intake process. All three pathways result in the same practical outcome for the practice — the patient is the financial obligor — but the operational steps and the documentation the practice must provide differ by pathway.

Pathway 1: The Carrot Card

The Carrot Card is a prepaid debit card loaded with funds from the employer's Carrot benefit wallet. Patients with access to the Carrot Card present it at the time of payment like any credit or debit card. The practice runs the card through its standard payment terminal, the transaction is approved or declined based on the available balance, and the payment posts to the practice's bank account like any card transaction. From the practice's accounting perspective, a Carrot Card transaction is functionally equivalent to a patient paying with a personal debit card charged against their employer benefit. The practice does not submit a claim to Carrot, does not receive an EOB from Carrot, and does not separately reconcile a Carrot payment against an expected insurance payment. The Carrot Card patient who pays in full at the time of service has a zero balance after payment — standard patient receipts and itemized superbills satisfy the documentation requirement. The most common operational failure with Carrot Card payments is an insufficient balance: the card declines because the patient's available Carrot balance is less than the service charge. Train front desk staff to always verify the patient's current Carrot balance before scheduling any high-cost service, and have a written policy for collecting the balance in excess of the available Carrot benefit — by credit card, payment plan, or alternative financing — before the service is rendered, not after.

Pathway 2: Patient Reimbursement Submission

Patients without a Carrot Card, or patients whose employers use a reimbursement-only Carrot model, pay the practice out of pocket and then submit documentation to Carrot for reimbursement from their benefit wallet. In this pathway, the patient pays the practice's self-pay rate at the time of service — in full, or on the practice's standard payment plan — and then uploads receipts and invoices to the Carrot platform to recover the payment from their employer's benefit allocation. The practice's role is to provide the patient with documentation that Carrot will accept for reimbursement processing. Carrot requires itemized documentation that identifies the service provider, the date of service, the service rendered, and the amount charged. An itemized superbill or itemized patient statement that includes CPT codes and provider information is the standard document format that satisfies Carrot's reimbursement documentation requirements. Practices that provide only global invoices without CPT-level itemization create delays and denials in the patient's Carrot reimbursement process — generate the correct documentation from the start and avoid the downstream patient relations problem.

Pathway 3: Carrot Expert Provider Direct Billing

Carrot maintains a network of fertility clinics designated as Carrot Expert Providers. These clinics have a direct operational relationship with Carrot that enables streamlined patient referrals, coordinated care workflows, and in some configurations, direct billing through the Carrot provider portal. The Carrot Expert designation is obtained through a credentialing and onboarding process with Carrot's provider relations team. Practices that achieve Carrot Expert status may access a Carrot provider portal through which patient benefit information can be verified, treatment plans documented, and invoices submitted for direct reimbursement from the employer's Carrot benefit allocation without requiring the patient to submit individual reimbursement requests. The direct billing workflow for Carrot Expert providers is governed by the Carrot Expert provider agreement, which establishes required documentation formats, submission timelines, and payment terms. Practices with high Carrot patient volume should evaluate the Carrot Expert Provider designation as a revenue cycle optimization — it reduces patient friction in the reimbursement process and provides the practice with greater visibility into patient benefit availability before services are rendered.

Eligibility and Benefit Verification for Carrot Members

Benefit verification for Carrot patients looks completely different from standard insurance eligibility checks. The practice cannot run a Carrot eligibility transaction through a clearinghouse. The authoritative source for the patient's Carrot benefit information is the Carrot member platform itself, accessed by the patient through the Carrot mobile app or web portal. The practice should require the patient to complete benefit verification steps through their Carrot account before the initial consultation and provide the practice with written confirmation of their available benefit balance and covered services. The following items must be confirmed before any treatment services are ordered:

• Available benefit balance: The patient's current available Carrot benefit balance, expressed in dollars. Carrot benefits are denominated in dollars, not cycle counts. The available balance determines how much of the planned treatment can be funded through the Carrot benefit before the patient reaches self-pay responsibility.
• Covered service categories: The specific fertility services covered under the patient's employer Carrot plan. Coverage varies significantly — some plans cover IVF, IUI, egg freezing, PGT, and donor services; others cover a narrower set. Never assume IVF is covered because the patient has a Carrot benefit. Confirm coverage for each specific service category in the treatment plan before clinical services begin.
• Benefit year or lifetime structure: Whether the benefit is structured as an annual allowance that resets, a lifetime maximum that does not reset, or a per-event allocation. Annual benefits require tracking against the benefit year end date; lifetime benefits require cumulative tracking across all prior claims applied to the maximum.
• Carrot Rx eligibility: Whether the patient's employer plan includes the Carrot Rx pharmacy benefit for fertility medications. Carrot Rx routes specialty fertility medications through its own pharmacy network, separate from the patient's general prescription drug benefit. If Carrot Rx is active, direct patients to Carrot's pharmacy coordination pathway for Gonal-F, Menopur, Follistim, and other injectable stimulation medications rather than routing through the general pharmacy plan.
• Underlying insurance coordination: Whether the patient also carries traditional health insurance and how the two benefits should be coordinated. If the patient has underlying insurance that covers fertility diagnostics, ovulation induction monitoring, or other fertility-adjacent services, the patient may use insurance for those services and reserve Carrot funds for IVF-specific costs not covered by insurance.
• Payment pathway confirmation: Whether the patient will pay using a Carrot Card, self-pay with reimbursement submission, or through the direct billing pathway if the practice is a Carrot Expert Provider. Establish the payment pathway before the first service is rendered and document it in the patient's financial record.

Itemized Superbill Requirements for Carrot Reimbursement

The practice's superbill is the primary document that enables Carrot patients to submit reimbursement requests to the Carrot platform and, in the Carrot Expert direct billing pathway, supports the practice's own invoice submission. Carrot requires itemized documentation, not global invoices. A superbill that lists only 'IVF cycle — $12,500' without CPT-level itemization is insufficient for Carrot reimbursement purposes and will delay or prevent the patient from recovering their payment from the benefit wallet. Every fertility service must be individually itemized on the superbill. The following table covers the most frequently billed CPT codes in a standard fertility practice and the documentation notes relevant to Carrot reimbursement:

The superbill must include the practice's NPI, federal tax ID, address, and phone number; the patient's name and date of birth; each service's date of service; each CPT code with its lay description; the charge amount per code; and the attending physician's name and NPI. ICD-10 diagnosis codes should appear on the superbill even though Carrot does not adjudicate claims based on diagnosis criteria in the same way an insurer does — the codes support the patient's records, may be requested during an employer benefit audit, and provide the documentation chain needed if the patient's reimbursement request is questioned. Use specific, accurate ICD-10 codes reflecting the documented clinical diagnosis: N97.0 for anovulatory infertility, N97.1 for tubal factor infertility, N97.2 for uterine factor infertility, N97.9 for unspecified female infertility when the workup is complete or etiology is undetermined, Z31.83 as a secondary code for encounters for fertility treatment, Z31.62 for fertility preservation encounters, and the most specific N46.xx subcode for male infertility when the male partner is the patient of record.

IRS-Qualified Medical Expense Rules and Their Impact on Carrot Billing

Carrot employer benefit accounts are frequently structured under Internal Revenue Code Section 105 as employer-sponsored medical expense reimbursement plans, or under HRA (Health Reimbursement Arrangement) regulations. These structures require that reimbursable expenses qualify as medical expenses under IRS Publication 502. Most standard fertility services — IVF, IUI, egg freezing for documented medical necessity, embryo cryopreservation, embryo storage, PGT with a genetic indication, and fertility medications — qualify as IRS-recognized medical expenses and are reimbursable from a medical expense-based Carrot benefit. However, several services commonly billed in fertility practices are in gray zones or are explicitly excluded from IRS Section 213 medical expense status: elective egg freezing without a documented medical indication sits in uncertain territory under IRS guidance and may not be reimbursable through a medical expense plan; surrogacy agency fees and legal fees for gestational carrier arrangements are generally not IRS-qualified medical expenses even though Carrot employer plans may contractually cover them as a family-building benefit outside the medical expense structure; adoption-related expenses may be handled through a separate adoption benefit rather than the medical benefit; and PGT for embryo selection without a documented genetic indication may be subject to employer plan coverage limitations. When patients ask whether a specific service will be reimbursed through their Carrot account, refer them to the Carrot platform's coverage documentation and, for tax-specific questions, to their benefits administrator or tax advisor — the practice should not offer tax advice about the reimbursability of specific fertility services under the patient's specific employer plan structure. The practice's responsibility is to ensure the superbill clearly identifies each service with its CPT code and date of service, so the patient and Carrot can make the appropriate coverage and eligibility determination without ambiguity about what was performed.

Coordinating Carrot With Underlying Insurance

Many Carrot members also carry traditional group health insurance. In states with fertility insurance mandates — Illinois, New York, New Jersey, California, Massachusetts, Arkansas, Connecticut, Delaware, Hawaii, Louisiana, Maryland, Montana, New Hampshire, Ohio, Rhode Island, Texas, Utah, and West Virginia among others as of 2026 — the underlying insurance plan may cover IVF, IUI, and fertility diagnostics up to a benefit maximum. When a Carrot member also has active fertility insurance coverage, the practice must apply the two benefits in the correct sequence to prevent double-payment problems and to maximize the patient's combined benefit recovery. The correct sequencing is: insurance first, Carrot second. The practice bills the underlying insurance for covered fertility services using the standard claims submission workflow — the same CPT codes, ICD-10 codes, prior authorization requirements, and timely filing rules that apply to that insurer. The patient's Carrot benefit then becomes available to cover cost-sharing obligations such as deductibles, copays, and coinsurance, as well as services not covered under the underlying insurance plan. For reimbursement submission purposes, the patient submits both the insurance Explanation of Benefits showing the applied cost-sharing and the practice's itemized invoice to the Carrot platform to document the out-of-pocket amounts that qualify for Carrot reimbursement. Practices that allow Carrot patients to bypass insurance billing and pay entirely through Carrot — because collecting through Carrot at the time of service is faster and administratively simpler than waiting on insurance adjudication — expose the patient to a permanent loss of insurance benefits for those services and create a coordination of benefits problem that may constitute a fraud risk if the patient then submits Carrot reimbursement for services already covered by insurance. Establish a written clinical operations policy: every Carrot patient with concurrent insurance coverage must have insurance billed first before Carrot funds are applied to any service covered under the insurance benefit.

Patient Financial Counseling for Carrot Members

Financial counseling for Carrot members requires a modified framework compared to standard insurance or self-pay patients. The counselor must cover the following items at the initial consultation — before any treatment cycle is ordered — and document the discussion in the patient's financial record:

• Explain the difference between Carrot and insurance: Most Carrot members arrive at the practice believing Carrot will pay the clinic directly like an insurer. Correct this assumption at the first patient contact. The patient is the financial obligor — the practice will collect payment from the patient, either through the Carrot Card at the time of service or through direct payment that the patient submits to Carrot for reimbursement. Document this in the practice's financial policy acknowledgment form and obtain the patient's signature before services begin.
• Calculate the benefit-to-cost gap before treatment planning: Use the patient's confirmed Carrot balance and the practice's itemized cycle cost estimate to identify the out-of-pocket gap — the amount owed beyond the available Carrot benefit. For a $15,000 IVF cycle with a $10,000 Carrot balance, the minimum gap is $5,000, not accounting for medications, PGT, anesthesia, or subsequent cycle costs. The patient must understand and financially plan for this gap before stimulation begins, not after the retrieval.
• Confirm what the Carrot benefit does not cover for this specific patient: Verify exactly which services in the proposed treatment plan are covered under the patient's employer Carrot plan and which are not. PGT, anesthesia billed by the anesthesiology group, embryo storage beyond the cryopreservation cycle, and certain ancillary fees are frequent plan exclusions. Services not covered by Carrot are the patient's full self-pay responsibility and must be disclosed in writing at the time of financial counseling.
• Address Carrot Rx medication routing before stimulation medications are prescribed: If the patient has Carrot Rx, provide written instructions on how to route injectable fertility medications through the Carrot Rx pharmacy network. Patients who fill stimulation medications at a retail or specialty pharmacy outside the Carrot Rx network may spend out-of-pocket funds they cannot recover from their Carrot benefit because the dispensing pharmacy is not recognized by the platform.
• Establish a payment plan for amounts exceeding the Carrot benefit: Any portion of the treatment cost not covered by the available Carrot balance requires a separate payment arrangement — credit card, patient financing (Prosper Healthcare Lending, CareCredit), or a practice-administered payment plan. Execute the payment plan agreement in writing before the stimulation cycle begins. Do not start a stimulation cycle without a fully executed financial agreement that covers the entire estimated cost including the balance beyond the available Carrot funds.
• Provide a written cycle-level cost estimate at the consultation: Generate an itemized written cost estimate showing the expected charges for each service in the planned treatment cycle, organized by CPT code. The estimate should clearly distinguish between what the practice will collect via the patient's Carrot benefit and what requires supplemental payment. Provide this document at the consultation appointment — it is the financial planning tool the patient uses to make the self-pay gap arrangement and the document they reference if a billing discrepancy arises later.

Common Carrot Billing Failures and How to Prevent Them

• Routing Carrot patients through the insurance billing workflow: The most structurally consequential failure. When a Carrot patient is flagged as an insurance patient in the practice management system and routed to the insurance billing queue, a claim is generated for a payer with no mechanism to receive or process it. The account sits in A/R for months with no payment and no denial — the claim simply never arrived anywhere. Carrot patients must be registered as self-pay or under a Carrot-specific financial class in the PMS, not as insurance patients. Create a dedicated Carrot financial class to support correct workflow routing and reporting.
• Providing inadequate superbill documentation: Patients who receive a global invoice without CPT-level itemization cannot complete a Carrot reimbursement submission. The Carrot platform requires line-level itemization by date of service. Train billing and checkout staff to generate the full CPT-coded superbill for every Carrot patient encounter and deliver it electronically at checkout — not upon patient request days or weeks later when the submission deadline may be approaching.
• Failing to verify available Carrot balance before high-cost services: A Carrot Card that declines at the payment terminal on retrieval day for a $10,000 balance creates a collection problem and a patient relations failure simultaneously. Implement a written policy requiring patient-confirmed Carrot balance verification — documented in the financial record — at least five business days before any high-cost service is scheduled. If the balance is insufficient, arrange supplemental payment before the service date, not at the point of service.
• Mixing Carrot funds and insurance billing without proper sequencing: Processing a Carrot Card payment for services that should have been billed to the underlying insurance first creates a coordination of benefits failure and eliminates the patient's ability to recover insurance benefits for those services. The sequencing rule — insurance first, Carrot second — must be a written operational policy applied consistently to every Carrot patient with concurrent insurance coverage.
• Not tracking cumulative Carrot fund drawdown across a multi-cycle plan: Patients undergoing sequential IUI cycles or multiple IVF attempts may exhaust their Carrot benefit mid-plan without warning if the practice does not track cumulative charges against the available balance. Build a Carrot balance tracking field into the patient financial record and update it after every Carrot Card transaction or patient payment. Alert the financial counselor when the projected remaining balance falls below the cost of one full treatment episode.
• Ignoring annual benefit resets: Carrot plans with annual benefit structures reset on the benefit year anniversary, not necessarily on January 1. A patient with a $15,000 annual benefit who started treatment in October and whose benefit year resets in February has a new $15,000 available in February. The practice may not know the reset occurred unless the patient proactively reports it. Document the benefit year end date in every Carrot patient's financial record at intake and schedule a proactive benefit update verification on or shortly before the reset date so the practice and patient can plan the next treatment episode against the refreshed benefit.

Operational Setup for Carrot Patient Accounts

Practices with consistent Carrot patient volume should implement the following operational infrastructure to manage Carrot accounts systematically and prevent the ad hoc failures that occur when Carrot patients are processed without a defined workflow. First, create a dedicated Carrot financial class in the practice management system that flags the account for self-pay processing, triggers CPT-coded superbill generation automatically at checkout, and routes the account to a financial counselor rather than the insurance billing queue. Second, develop a Carrot-specific intake packet that includes: a benefit verification checklist the patient completes through the Carrot app before the first appointment; a written explanation of how the Carrot benefit works relative to the practice's billing and collection process; a cycle-level itemized cost estimate for the anticipated treatment plan; and a financial agreement that establishes the payment mechanism and the plan for any charges exceeding the available Carrot balance. Third, train every front desk and patient access team member to recognize a Carrot patient at intake and route the account correctly from the first contact — a Carrot patient entered as an Aetna or United Healthcare patient in the PMS creates a workflow problem that may take 60 to 90 days to identify and correct. Fourth, establish a monthly Carrot A/R review that checks for accounts with patient balances outstanding beyond 30 days, Carrot Card decline events not resolved with a supplemental payment arrangement, and patients whose Carrot benefit has been depleted mid-treatment without a documented self-pay transition plan. Carrot billing failures are almost entirely preventable — they result from intake workflow gaps, not from Carrot platform failures — and systematic operational setup eliminates them before they reach accounts receivable.
