Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 88299 covers

CPT 88299 identifies a cytogenetic laboratory study that lacks a more specific listed procedure code. Cytogenetics laboratories assess chromosome structure or other cellular genetic features in testing ordered to investigate genetic or chromosomal conditions. The laboratory that performs the study reports the service. Select a listed code whenever its defined study matches the work performed; 88299 is for work not represented by a specific cytogenetic procedure code.

For Medicare, 88299 is carrier-priced (status C): CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The claim should identify the study performed and include information that lets the contractor assess the service represented. This payment status does not make 88299 a substitute for a listed cytogenetic procedure code that fits the work.
