HCPCS Modifier US

Published 07/16/2020

Description
HCPCS Modifier US is used with portable X-ray HCPCS code R0075 (transportation component) when six or more Medicare patients are served at the same location.

Guidelines and Instructions

  • Submit this modifier with portable X-ray HCPCS code R0075 (transportation component) when six or more Medicare patients are served at the same location
  • The units field must reflect "1" except in extremely unusual circumstances. The units field must never be used to report the number of patients served during a single trip. The units field must reflect the number of services that the specific beneficiary received and not the number of services received by other beneficiaries.
  • Note: If only one patient is seen at a particular location, report HCPCS code R0070 with no modifier since the description for this code specifies that one patient was seen
