What 17311 covers

Mohs micrographic surgery removes a skin cancer, usually basal cell or squamous cell carcinoma, in mapped stages. The Mohs surgeon excises the tumor, maps and color-codes the tissue, oversees frozen-section processing, and personally examines slides for peripheral and deep margins. Code 17311 covers the first stage and up to five tissue blocks for a tumor on the head, neck, hands, feet, or genitalia. It also covers tumors at other sites when surgery directly involves muscle, cartilage, bone, tendon, major nerves, or vessels. Mohs-trained dermatologic surgeons usually perform this work in an office.

Report one unit per distinct tumor’s first stage. Document the tumor site, biopsy diagnosis, stage maps, block count, and surgeon’s slide interpretation. Report additional stages with 17312 and each block beyond five in a stage with 17315; report qualifying defect repairs separately. The 0-day global period includes same-day preoperative and postoperative care. For multiple procedures in one session, CMS pays the highest-valued procedure in full and reduces other procedures subject to the multiple-procedure rule to 50%. Modifier 50 is inappropriate for 17311; assistant-at-surgery payment is prohibited, and co-surgeon and team-surgery arrangements 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.

17311 billing questions

When should 17311 be chosen over 17313?

Use 17311 when the tumor is on the head, neck, hands, feet, or genitalia, or when surgery at any site directly involves muscle, cartilage, bone, tendon, major nerves, or vessels. Use 17313 for trunk, arm, or leg tumors without that deep-structure involvement.

How are two separate tumors treated by Mohs on the same day reported?

Report the appropriate first-stage code once for each distinct tumor. Use modifier 59 when needed to identify a separate lesion, or XS when the lesions are on separate anatomical structures; the lower-valued procedure is subject to CMS’s multiple-procedure reduction.

Can the Mohs surgeon bill 88305 or 88331 for the frozen sections?

No. The Mohs code includes the surgeon’s pathology work on the Mohs sections. Pathology may be separately reportable for a distinct diagnostic specimen, such as a same-day biopsy needed to establish the diagnosis before Mohs surgery.

Is repair of the Mohs defect included?

No. A qualifying layered or complex closure, adjacent tissue transfer, flap, or graft may be reported separately. A separately reported repair may be subject to CMS’s multiple-procedure reduction.

What if the first stage requires more than five tissue blocks?

Report add-on code 17315 for each block beyond five in the stage. The first five blocks are included in 17311.

Can an E/M be billed on the day of Mohs surgery?

Yes, when the E/M is significant and separately identifiable from the routine same-day preoperative and postoperative care included in 17311. Append modifier 25 to the E/M 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.
