Select and report the appropriate ICD-10-CM diagnosis code for melanoma on the claim.

BRAF V600 mutation testing (cobas® 4800 BRAF V600) is covered to detect BRAF mutation in melanoma to determine eligibility for vemurafenib (Zelboraf) in patients with melanoma that is unresectable or metastatic.
BRAF V600E and V600K mutation testing (ThxID™ BRAF V600/K) is covered to identify melanoma patients whose tumors carry V600E and/or V600K mutations for selection of dabrafenib (Tafinlar) and/or trametinib (Mekinist).
Mohs micrographic surgery is covered when selected because the lesion's complexity (e.g., poorly defined borders, suspected deep invasion, recurrent lesion, prior radiation), size, or anatomic location requires maximal tissue conservation and other approaches (standard excision or destruction) are not medically reasonable or necessary.
Mohs surgery is considered covered when the surgeon performs both the surgical excision and the pathologic examination (surgeon acting in integrated surgical and pathology roles) as part of the Mohs technique.
Lab-developed tests for inherited cancer syndromes in patients with cancer as described in Local Coverage Determination (LCD) L39040 are the services addressed by this billing/coding guidance.
