About Z46.8

Z46.8 is the ICD-10-CM diagnosis code for encounter for fitting and adjustment of other specified devices. It belongs to category Z46 (encounter for fitting and adjustment of other devices), 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 3 subcodes must be used instead.

Within Z46, choose Z46.8 (other specified devices) only when documentation doesn't support a more specific option: spectacles and contact lenses (Z46.0), hearing aid (Z46.1), related to nervous system and special senses (Z46.2), dental prosthetic device (Z46.3), orthodontic device (Z46.4), other gastrointestinal appliance and device (Z46.5), urinary device (Z46.6) and unspecified device (Z46.9).

To report this condition, pick the subcode that matches the documentation: Z46.81 (pump), Z46.82 (catheter) and Z46.89 (devices).

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