About 10021: Fine needle aspiration without imaging guidance

Reports needle aspiration of a first lesion for cell or fluid sampling when the clinician performs the procedure without imaging guidance.

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%.

10021 billing questions

When should 10021 be used instead of 10005?

Use 10021 for aspiration of the first lesion without imaging guidance. Use 10005 when ultrasound guidance is used for the first lesion.

How are additional lesions reported?

Report 10021 for the first lesion and 10004 for each additional distinct lesion sampled without imaging guidance. Repeated needle passes into the same lesion do not make it an additional lesion.

Does 10021 include cytology interpretation?

It reports the aspiration procedure, not the separate cytologic examination. The examination may be reported separately when performed and supported.

What documentation supports 10021?

Identify the lesion and its site, document the aspiration and specimen obtained, and make clear that imaging guidance was not used. Distinguish each separately sampled lesion.

How does the multiple procedure reduction affect 10021?

When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and the others at 50%. The payment order depends on the relative values of the procedures performed.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
