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.
