Help with excision code

[drhoads]

Physician excised a subcutaneous mass right posterior neck 1.5 cm. Excised carried down through the subcutaneous tissue. Path report states it is a metastic adenocarcinoma. I was thinking using cpt 21555 with dx 173.40 but not 100% sure???? Help...new coder.

Thank you

I think your choices are good, but why do you think they are not?

I am just so new at coding, I guess I just second guess myself.

Thank you

No problem. Just thought there might have been something additional in the medical note.

why 21555 why not 11622, just wondering

Tumor I would go with 21555 if path says soft tissue.

If just skin go with 11622

173.40 is for skin, this is subq with mets so i would use 198.89 and 199.1 for primary site unknown.
