KX and GA Modifiers
The KX and GA modifiers are available to be turned on in the patient chart on a per case basis. These modifiers are used once the Medicare Therapy Cap has been reached.
- Using the KX modifier notifies Medicare that the treatment is medically necessary. Attaching the KX modifier to documentation and claim forms will attest that the services billed: are reasonable and medically necessary, have supporting documentation is on file, qualify for therapy cap exception, and requires the skill of a PT/OT/SLP.
- Using the GA modifier notifies Medicare that an ABN is on file and non-covered charges by Medicare will be the responsibility of the patient. By adding the GA modifier, Medicare will reject the claim and send the denial. You can then collect the non-covered charges from the patient.
