Z45Encounter for adjustment and management of implanted device

Z45 is the ICD-10-CM diagnosis code for encounter for adjustment and management of implanted 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Z45.0 (device), Z45.1 (pump), Z45.2 (device), Z45.3 (s of the special senses), Z45.4 (device), Z45.8 (devices) and Z45.9 (device).

Don't report Z45 together with the conditions in its Excludes1 note: malfunction or other complications of device - see Alphabetical Index.

The conditions in its Excludes2 note aren't part of Z45, but may be coded alongside it if the patient has both: encounter for fitting and adjustment of non-implanted device (Z46.-).

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