About Z46
Z46 is the ICD-10-CM diagnosis code for encounter for fitting and adjustment of other devices. 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 9 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: Z46.0 (lenses), Z46.1 (aid), Z46.2 (related to nervous system and special senses), Z46.3 (device), Z46.4 (device), Z46.5 (device), Z46.6 (device), Z46.8 (devices) and 1 more.
Don't report Z46 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 Z46, but may be coded alongside it if the patient has both: encounter for fitting and management of implanted devices (Z45.-), issue of repeat prescription only (Z76.0) and presence of prosthetic and other devices (Z95-Z97).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
