S4011
Complete IVF Cycle (S Code — Mandate Payers)
Bundled case-rate code for a complete IVF cycle, with or without ICSI — used by fertility mandate payers and fertility benefit managers (FBMs) to track cycle utilization against benefit limits. S4011 represents a complete cycle including egg retrieval and embryo transfer.
Billing Notes
S codes have no direct reimbursement value — they are cycle utilization tracking codes required by specific payers. Missing S codes result in claim rejections (not denials) requiring resubmission. Aetna, certain BCBS plans, and FBMs commonly require S codes.
Diagnosis Codes
Common Denial Reasons
- S code missing — claim rejected (not denied) for resubmission
- Wrong S code — S4011 vs S4015 vs S4025 selection error
- S code submitted to payer that does not require them
Payer Notes
S codes are submitted alongside CPT codes, not as replacements. Always verify which S codes the specific payer requires before submitting. S4011 is for a complete IVF cycle; S4015 adds embryo transfer to S4011.
