What 11310 covers

A clinician removes a small skin lesion by shaving it tangentially from the epidermal or dermal surface. This code is for lesions on the face, ears, eyelids, nose, lips, or mucous membrane, including a raised lesion such as a seborrheic keratosis or nevus. Dermatologists commonly perform the service in an office; other qualified clinicians may perform it in office or facility settings. Tissue may be sent for histopathology when indicated.

Select the code using the lesion’s documented size and anatomic site; this code is for a lesion measuring 0.5 cm or less at one of the specified sites. Record the exact site, lesion measurement, and removal technique. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery payment requires documentation of medical necessity; 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.

11310 billing questions

How does this differ from 11300 or 11305?

Those codes cover the same small size range at different anatomic sites. Use 11310 for the face, ears, eyelids, nose, lips, or mucous membrane.

When should 11311 be used instead?

Use 11311 for a shave-removed lesion at the same specified sites when it measures 0.6 to 1.0 cm. The size documented for the lesion determines the size level.

Is a shave removal the same as a tangential skin biopsy?

No. 11310 reports removal of a small lesion; 11102 is the tangential biopsy code when the service is a biopsy of a single lesion.

How should multiple lesions removed in one session be reported?

Document each lesion’s site and size and report the services separately as appropriate. The CMS multiple-procedure reduction applies when procedures are performed in the same session.

Does the 0-day global period include a later pathology visit?

The 0-day global period includes same-day preoperative and postoperative care. It does not define a later pathology-related service as part of the same-day care.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.

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.
