Radiology or Other Diagnostic Unlisted Service or Procedure
120 - Radiology or Other Diagnostic Unlisted Service or Procedure
Billing Instructions for A/B MAC (A) Claims
(Rev. 1, 10-01-03)
Some radiology and other diagnostic services may not have a corresponding HCPCS
code. This is because these are typically services that are rarely provided, unusual, or
new. The provider should assign the appropriate “unlisted procedure” code to any such
service. The following list contains the “unlisted procedure” codes along with the
suggested revenue code for billing. These services are paid on a fee schedule if one
exists or cost if a fee has not been established for SNFs. However, before billing any of
these codes the provider needs to furnish a complete description of the radiology
procedure to the A/B MAC (A) for review and analysis. The description should include a
narrative definition of the procedure and a description of the nature, extent and need for
the procedure and the time, effort, and equipment necessary. The A/B MAC (A) will
determine if the provider has correctly identified the procedure as “unlisted.” If the
procedure is not identified correctly, the A/B MAC (A) will inform the provider of the
correct HCPCS code to assign to the procedure. If there is no fee schedule amount
established, these services are paid based on cost to SNFs.
