About the Z99 Code Range
Dependence on an enabling machine or device is a health status, not the name of a disease. Z99 groups these statuses by the machine or device involved.
The subdivisions identify an aspirator, respirator, renal dialysis, wheelchair, or other enabling equipment. Respirator codes distinguish dependence status from an encounter during a power failure. The other-equipment codes distinguish supplemental oxygen from other machines and devices.
