About coding breast puncture
The ICD-10-CM code for breast puncture is S21.039 (Puncture wound without foreign body of unspecified breast). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S21.039.
Within S21.03, choose S21.039 (unspecified breast) only when documentation doesn't support a more specific option: right breast (S21.031) and left breast (S21.032).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
