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.

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.
