About Z99.8
Z99.8 is the ICD-10-CM diagnosis code for dependence on other enabling machines and devices. It belongs to category Z99 (dependence on enabling machines and devices, not elsewhere classified), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) 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 2 subcodes must be used instead.
Within Z99, choose Z99.8 (other enabling machines and devices) only when documentation doesn't support a more specific option: aspirator (Z99.0), respirator (Z99.1), renal dialysis (Z99.2) and wheelchair (Z99.3).
To report this condition, pick the subcode that matches the documentation: Z99.81 (oxygen) and Z99.89 (devices).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
