I need help clarifying the coding for MOHS. If you are billing for 6 stages...would the correct billing be 17311 (first stage); 17312 x 5 units or would it be 17311 (first stage); 17312 x 4units; 17315 x 1unit? I am not clear is 17311 and 17312 should total 5 together?

Codes depend on location of Mohs surgery. Code17311 is for head, neck, hand, feet, genitalia etc. You did not mention if surgery was done on Head,etc. I would guess the head. the code would be 17311 and 17312 x 5 for a total of six stages. Code 17315 is for each additional block after the first 5 tissue blocks, any stage. My understanding is if 6 tissue blocks were taken on any stage you would use 17315. If stage one, two, three and four had six tissue blocks you would code as follows:

17311, 17315, 17312 x 5 17315 x3
