89280
ICSI — Up to 10 Oocytes
Intracytoplasmic sperm injection (ICSI) for 10 or fewer oocytes. ICSI is the fertilization technique in which a single sperm is injected directly into an egg. The number of oocytes injected determines whether to use 89280 or 89281.
Billing Notes
Use 89280 when 10 or fewer mature oocytes are injected. Use 89281 when more than 10 oocytes are injected. Document the exact oocyte count in the procedure note — payers frequently audit this. Never bill both 89280 and 89281 in the same cycle.
Diagnosis Codes
Common Denial Reasons
- 89281 billed when oocyte count is ≤10 (overbilling flag)
- 89280 billed when count is >10 (underbilling / documentation mismatch)
- Missing oocyte count in embryology report
- ICSI not covered for non-male-factor indication
Payer Notes
Some payers cover ICSI only for documented male factor infertility. Others cover it routinely as part of IVF. Verify per payer before submitting ICSI codes without a male factor diagnosis.
