CPT code 10012: MR-guided FNA, each additional lesion2026 Medicare rate & RVUs

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

What 10012 covers

This add-on code describes fine-needle aspiration biopsy of an additional lesion using magnetic resonance guidance. A physician, commonly a radiologist or another clinician performing image-guided procedures, advances a needle into the target and obtains material for evaluation. The code applies to each additional lesion after the first lesion sampled with MR guidance; it is not the code for the initial lesion.

Medicare assigns status C, meaning CMS publishes no national payment and the Medicare Administrative Contractor sets payment for each claim. Report 10012 only with the primary MR-guided fine-needle aspiration procedure, 10011. CMS identifies it as an add-on code paid within the primary procedure's global period. The reported quantity follows the number of additional lesions sampled during the procedure.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
