About Z44

Z44 is the ICD-10-CM diagnosis code for encounter for fitting and adjustment of external prosthetic device. It belongs to 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Z44.0 (arm), Z44.1 (leg), Z44.2 (eye), Z44.3 (prosthesis), Z44.8 (devices) and Z44.9 (device).

Don't report Z44 together with the conditions in its Excludes1 note: malfunction or other complications of device - see Alphabetical Index and presence of prosthetic device (Z97.-).

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