Summary & Overview
HCPCS K0899: Power Mobility Device Not Coded by DME PDAC
HCPCS Level II code K0899 designates a power mobility device that is not coded by the DME PDAC or does not meet PDAC criteria. This code functions as a catch-all for motorized mobility equipment lacking a specific PDAC-assigned HCPCS code and is used in billing when a manufacturer- or model-specific code is absent. Nationally, K0899 matters because it affects coverage determinations, prior authorization workflows, and claims processing for beneficiaries needing powered mobility to maintain independence and function.
Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for power mobility devices, common billing and coding implications for equipment without PDAC coding, and guidance on what content is available versus missing. The publication outlines typical sites of service (home and community use) and examines payer coverage patterns, utilization benchmarks where available, and relevant policy updates or administrative processes impacting reimbursement eligibility.
This summary is intended for clinicians, DME suppliers, billing professionals, and policy analysts seeking a national-level briefing on billing and administrative considerations tied to K0899. Data not available in the input will be noted where applicable in detailed sections.
Billing Code Overview
HCPCS Level II code K0899 describes a power mobility device that is not coded by the DME PDAC or does not meet PDAC coding criteria. The designation covers power wheelchairs or other motorized mobility aids that lack an assigned PDAC HCPCS code or fail to meet PDAC-determined coding requirements.
Service Type: Durable medical equipment — power mobility device
Typical Site of Service: Home or community settings where personal mobility devices are used
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with progressive neuromuscular weakness and significant mobility limitation is evaluated for a power mobility device. The patient uses a cane or manual wheelchair but is unable to safely ambulate in the community due to decreased endurance, limited trunk control, and motor deficits. A durable medical equipment supplier documents that the requested power mobility device does not meet Medicare PDAC coding criteria or is not listed in the DME PDAC database, qualifying the device for billing under K0899 (Power mobility device, not coded by DME PDAC or does not meet criteria). The clinical workflow includes an evaluation by a rehabilitation physician or occupational therapist to document functional limitations, a face-to-face mobility assessment to establish medical necessity, completion of supplier documentation (prior authorization if required by the payor), and delivery with patient education and follow-up mobility training. Typical sites of service include outpatient rehabilitation clinics, hospital-based DME departments, and durable medical equipment suppliers with home delivery and in-home setup services.
