Z44.3Encounter for fitting and adjustment of external breast prosthesis

Z44.3 is the ICD-10-CM diagnosis code for encounter for fitting and adjustment of external breast prosthesis. It belongs to category Z44 (encounter for fitting and adjustment of external prosthetic device), block Z40-Z53 (Encounters for other specific health care) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within Z44 (encounter for fitting and adjustment of external prosthetic device), Z44.3 is specifically for encounter for fitting and adjustment of external breast prosthesis. Related codes cover artificial arm (Z44.0), artificial leg (Z44.1), artificial eye (Z44.2), other external prosthetic devices (Z44.8) and unspecified external prosthetic device (Z44.9).

To report this condition, pick the subcode that matches the documentation: Z44.30 (unspecified breast), Z44.31 (prosthesis) and Z44.32 (prosthesis).

Don't report Z44.3 together with the conditions in its Excludes1 note: complications of breast implant (T85.4-), encounter for adjustment or removal of breast implant (Z45.81-), encounter for initial breast implant insertion for cosmetic breast augmentation (Z41.1) and encounter for breast reconstruction following mastectomy (Z42.1).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
