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

What 10021 covers

A clinician uses a fine needle to withdraw cells or fluid from a lesion for diagnostic evaluation, without ultrasound, fluoroscopic, CT, or MR guidance. This may be performed in an office or procedure room when the target can be located clinically, such as a palpable thyroid nodule or superficial lymph node. The code represents sampling of the first lesion; cytologic examination of the specimen is a separate service when performed and appropriately reported.

Choose this code based on the absence of imaging guidance, not the lesion’s size or the number of needle passes. Document the target’s site and identity, the aspiration performed, and that no imaging guidance was used. For each additional distinct lesion sampled without imaging guidance, use 10004 rather than reporting another unit of 10021. When multiple procedures are performed in the same session, CMS applies the standard multiple procedure reduction: the highest-valued procedure is paid in full and the others at 50%.
