Z48Encounter for other postprocedural aftercare

Z48 is the ICD-10-CM diagnosis code for encounter for other postprocedural aftercare. 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Z48.0 (drains), Z48.1 (closure), Z48.2 (transplant), Z48.3 (neoplasm) and Z48.8 (aftercare).

Don't report Z48 together with the conditions in its Excludes1 note: encounter for follow-up examination after completed treatment (Z08-Z09) and encounter for aftercare following injury - code to Injury, by site, with appropriate 7th character for subsequent encounter.

The conditions in its Excludes2 note aren't part of Z48, but may be coded alongside it if the patient has both: encounter for attention to artificial openings (Z43.-) and encounter for fitting and adjustment of prosthetic and other devices (Z44-Z46).

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