Hi,

I would code it as 22999 - Unlisted procedure, abdomen, musculoskeletal system.

It's more than a skin code because the surgeon excised all the way down through the subcutaneous tissue. Yet, he did not enter the peritoneal cavity either.

I would base my fee on about the same RVUs as code 22900 as the work seems similar & send the op note w/ claim.

Good luck,
:) Erica
