Laboratory — Genetic Testing
89291
Embryo Biopsy — 6+ Embryos (PGT)
Biopsy of oocyte polar body or embryo for preimplantation genetic testing — 6 or more embryos. The higher reimbursement vs 89290 reflects the additional embryology labor for biopsying larger cohorts.
Billing Notes
Use 89291 when 6 or more embryos are biopsied. Use 89290 for 1–5 embryos. As with 89290, this code covers the embryology biopsy component only — the genetic analysis is billed by the reference lab.
Diagnosis Codes
N96 (recurrent pregnancy loss), Z13.88 (genetic screening), Q95.x (chromosomal rearrangement)
Common Denial Reasons
- 89290 billed when 6+ embryos are documented
- Embryo count not specified in documentation
- Payer bundles both biopsy and analysis under single PGT rate
Payer Notes
Same payer coverage rules as 89290. Larger embryo cohorts typically arise from higher-stimulation cycles — confirm the clinical documentation supports the embryo count.
