Dependence on enabling machines and devices, not elsewhere classified (Z99) ICD-10-CM
The Z99 code range covers dependence on enabling machines and devices, not elsewhere classified with 10 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

About the Z99 Code Range
The Z99 ICD-10 code section covers medical conditions where a person is dependent on machines or devices essential for daily living but not classified elsewhere. This includes reliance on respiratory support, dialysis, wheelchairs, and other assistive technologies.
Z99.0 identifies dependence on an aspirator to clear airways, while Z99.1 and Z99.11 specify dependence on a respirator or ventilator, often known as being on artificial ventilation or mechanical breathing support. Codes like Z99.12 address situations involving respirator dependence during power failures. Z99.2 relates to dependence on renal dialysis for kidney failure treatment, often linked to end-stage renal disease. Z99.3 describes dependence on a wheelchair for mobility, including use of electric or manual chairs. Other codes such as Z99.81 detail dependence on supplemental oxygen, crucial for patients requiring continuous or intermittent oxygen therapy at home or during activity. Lastly, Z99.89 captures dependence on various enabling devices like walking aids or stair lifts. These codes help medical coders identify specific dependencies on life-supporting or mobility-assisting equipment in patient records accurately.
