Ankle-Foot-Orthoses/Knee-Ankle-Foot Orthoses Same or Similar Tip

Same or similar denials are a top denial for the Ankle-Foot Orthoses (AFO)/Knee-Ankle Foot Orthoses (KAFO) policy. This may be due to beneficiaries requiring an AFO/KAFO initially, then later, as their condition changes, they require another one for the change in medical condition. For example, many beneficiaries initially require a boot and then later move on to a long-term orthosis.

When providing a brace for a change in medical condition, suppliers should obtain an Advance Beneficiary Notice of Noncoverage (ABN) if the previous orthosis has not reached the reasonable useful lifetime (RUL), and submit the claim with the KX modifier when all requirements specified in the policy have been met. When the claim denies as same or similar, appeal the claim, justifying the change in medical condition with all medical records to support the change. Be sure to include the valid ABN with the appeal.

NOTE: The KX and GA modifiers may not be appended to the same claim line. This will cause a rejection of the claim for incorrect modifiers.
