Using the KX Modifier When Billing Manual Wheelchair Claims
The KX modifier signals that all Medicare coverage criteria for a manual wheelchair have been met. It should only be used when the patient meets the following:
- Has a mobility limitation affecting daily activities (e.g., toileting, dressing)
- Cannot use a cane or walker
- Will benefit from a manual wheelchair used regularly at home
- Can self-propel or have a caregiver to assist
Required Documentation
To support the KX modifier, suppliers must have:
- A signed Standard Written Order (SWO)
- Medical records meet the requirements of the Local Coverage Determination (LCD) and Policy Article for Manual Wheelchairs
- A home assessment
- Delivery documentation with item details
Do not use the KX modifier if any criteria are unmet-use GA or GZ instead. For more information review the HCPCS Modifier section within the LCD.
