About Z53

Z53 is the ICD-10-CM diagnosis code for persons encountering health services for specific procedures and treatment, not carried out. 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: Z53.0 (contraindication), Z53.1 (pressure), Z53.2 (reasons), Z53.3 (procedure), Z53.8 (reasons) and Z53.9 (reason).

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