Lower Limb Prostheses
CMS requires prior authorization of these six lower limb prostheses (LLP) HCPCS codes for all states and territories:
L5856, L5857, L5858, L5973, L5980, and L5987
We will base the prior authorization decision on Local Coverage Determination (LCD) L33787 and related Policy Article A52496.
How to Send Your Request
|
When to Expect the Decision We will send a detailed decision letter by the 10th business day following receipt of a request. Expedited requests: We will review the reason for the expedited request. If we decide there is a valid need for an expedited review, we will make reasonable efforts to send a decision within two business days. |
Deliver the Prostheses Within 120 Days
Prior authorization decisions for lower limb prostheses will remain valid for 120 calendar days after the provisional affirmation review decision. If the supplier does not deliver the prostheses within 120 calendar days of the decision, the supplier will need to send another prior authorization request.
If the beneficiary needs two items (for example, a foot and knee) that require prior authorization, send one prior authorization request for both codes.
The supplier may send one prior authorization request for both codes. However, we will issue two separate UTNs and two response letters, one for each code. Enter each UTN on the electronic claim 2400 – Service Line for the applicable HCPCs code.
