Z44.00Encounter for fitting and adjustment of unspecified artificial arm

Z44.00 is the ICD-10-CM diagnosis code for encounter for fitting and adjustment of unspecified artificial arm. 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 Z44.0, choose Z44.00 (unspecified artificial arm) only when documentation doesn't support a more specific option: complete artificial arm (Z44.01) and partial artificial arm (Z44.02).

To report this condition, pick the subcode that matches the documentation: Z44.001 (arm), Z44.002 (arm) and Z44.009 (unspecified arm).

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