About this policy
In order to facilitate claims processing and avoid denials for duplicate claims, claims which contain CPT ® /HCPCS codes describing services performed on anatomic structures that can be distinguished as left or right require laterality modifiers. This article is not a comprehensive listing of all such codes; however, all claims involving the CPT ® codes included in this article will be rejected unless the appropriate laterality modifiers (-RT; -LT) for unilateral procedures are reported. Bilateral procedures should be indicated by the appropriate modifier for bilateral procedures. CPT ® codes that are designated in their description as “unilateral or bilateral” do not require additional laterality modifiers. Claim lines for CPT ® /HCPCS codes requiring use of the RT and LT modifiers, submitted without the RT and/or LT modifiers or with the RT/LT on a single claim line will be rejected as incorrect coding.
