What 11420 covers

This code covers surgical removal of a small benign skin lesion from the scalp, neck, a hand, a foot, or the genitalia. Dermatologists, primary care clinicians, and surgeons may perform the procedure in an office or facility. The coded size is the greatest diameter of the lesion plus the margins removed, not the lesion alone. A suspected nevus or cyst may be removed for treatment or diagnosis; the record should identify the site and document the excised diameter and benign clinical assessment.

Choose this code only when the site falls within this group and the excised diameter is 0.5 cm or less. Use the appropriate sibling code when the diameter is larger, or a different site-specific code for another body region. The 10-day global period includes related postoperative visits during that period. 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. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery 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.

11420 billing questions

How is the lesion size determined?

Use the excised diameter, which includes the lesion and the margins removed. The documentation should support a diameter of 0.5 cm or less.

When should I choose 11421 instead?

Choose 11421 for a lesion at one of the same sites when the excised diameter is 0.6 to 1.0 cm. Code 11420 is limited to 0.5 cm or less.

Can modifier 50 be used for lesions on both sides?

No. Modifier 50 is inappropriate for this code. It describes an individual lesion excision, not a bilateral procedure.

Are postoperative visits separately reported during the global period?

Related postoperative visits during the 10-day global period are included in the procedure.

How are multiple procedures in the same session paid?

The highest-valued procedure is paid in full; other procedures in that session are subject to the standard multiple-procedure reduction and paid at 50%.

Can an assistant or co-surgeon be reported?

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.
