What 30100 covers

An otolaryngologist typically obtains a small tissue sample from inside the nose when examination identifies abnormal mucosa or a lesion that needs diagnostic evaluation. The clinician may use biopsy forceps through the nostril, often in an office setting, and submit the specimen for pathologic examination. The service is tissue sampling, not removal of an entire polyp or therapeutic excision of a lesion.

Report 30100 when tissue is sampled for diagnosis; document the intranasal site, the abnormal finding, the sampling performed, and specimen submission. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Do not use modifier 50; CMS bilateral adjustment does not apply. Medicare does not pay an assistant at surgery for this code, and co-surgeon and team-surgery billing are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

30100 billing questions

When should 30100 be used instead of an intranasal lesion excision code?

Use 30100 when tissue is sampled for diagnosis. When the service removes or excises the lesion rather than taking a diagnostic sample, consider the applicable lesion-removal code.

Is removal of a nasal polyp reported as 30100?

Not when the service is removal of the polyp. Codes 30110 and 30115 describe nasal polyp removal; 30100 is for intranasal tissue sampling.

Can modifier 50 be appended for biopsies on both sides?

No. CMS bilateral adjustment does not apply to 30100, and modifier 50 is inappropriate for this code.

What documentation supports reporting 30100?

Document the intranasal site and abnormal finding, the tissue sampling performed, and the specimen submitted for diagnostic evaluation.

How are other procedures in the same session paid?

Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50% when performed in the same session.

Can an assistant surgeon or co-surgeon be billed for 30100?

Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.

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.
