Laboratory — ICSI
89281
ICSI — More Than 10 Oocytes
Intracytoplasmic sperm injection (ICSI) for more than 10 oocytes. This code applies when 11 or more mature oocytes are injected in a single cycle. It carries a higher reimbursement rate than 89280 to reflect the additional laboratory labor.
Billing Notes
Oocyte count documentation is essential. If the embryology report documents ≤10 oocytes, 89281 will be denied and may trigger audit. If count is borderline, verify with the embryologist before submitting.
Diagnosis Codes
N46.11–N46.129 (male factor), N97.x (female infertility with ICSI for PGT)
Common Denial Reasons
- Oocyte count in documentation contradicts billed code
- Billed in a cycle where oocyte count is not documented
- Not covered for non-male-factor indication at specific payer
Payer Notes
Same coverage rules as 89280. Reimbursement for 89281 is typically 25–40% higher than 89280 — worth verifying documentation before defaulting to the lower code.
