So, I’m doing the AAPC CPC Study Guide and Ch 5 has a question that reads "A 4-year-old presents with an upper arm abscess in the subcutaneous tissue. An I&D is performed. Pus is expressed and dry gauze dressing is applied. The procedure is coded as:
A. 10060
B. 10061
C. 23930
D. 10180"

They say that the correct answer is A, going Incision and Drainage/Abscess/Skin.
Why would it not be C, though, for Upper Arm?

Any help is greatly appreciated.
