Price Range Across States
What You Might Pay
Estimated using RAND 2024 commercial-to-Medicare ratios. Actual prices vary by insurer, plan, and facility.
How we estimate these prices
These estimates are based on the RAND Hospital Price Transparency Study (4th Edition, 2024), which found that commercial insurance prices average 224% of Medicare rates nationally. We apply category-specific ratios: Genetic/Molecular Test procedures average 2.24x Medicare rates. Cash/self-pay estimates blend typical cash discounts (55% of billed charges) with Medicare-based estimates (150% of allowed amounts). These are statistical estimates, not quotes. Contact your insurer or provider for actual costs.

What the Data Says About Gene Analysis (isocitrate Dehydrogenase 1 [nadp+], Soluble) For Common Variants
Across 5 states with reporting providers, CPT code 81120 (Gene Analysis (isocitrate Dehydrogenase 1 [nadp+], Soluble) For Common Variants) shows a national average Medicare payment of $188.62 against an average billed charge of $409.39. That gap — a 2.2x markup, or 117% above the Medicare allowed amount — reflects chargemaster pricing, not what most insured patients actually pay. Medicare's negotiated rate is the statutory benchmark; commercial insurers typically settle between the two figures based on network contracts.
Genetic/Molecular Test procedures like this one saw 210 services billed to Medicare in 2023 by 26 distinct providers, serving 189 unique beneficiaries. State-level variation is significant: Texas reports the lowest average payment at $182.85, while Connecticut reports the highest at $189.38. Geographic Practice Cost Indices (GPCIs) explain much of that spread — local malpractice premiums, practice expense, and physician work adjustments all shift the allowed amount even when the procedure is identical.
Applying RAND 2024 commercial-to-Medicare ratios specific to the Genetic/Molecular Test category (2.24x), the estimated commercial insurance price lands near $422.51, with self-pay cash discounts commonly bringing the figure closer to $254.05. Uninsured patients facing the full billed charge have the strongest leverage to negotiate — the Hospital Price Transparency Rule (effective January 2021) requires providers to publish standard charges, cash rates, and payer-specific negotiated prices. This data is for educational reference; confirm coverage and out-of-pocket exposure with your insurer before any procedure.
