Surgical Dressings and RT/LT Modifiers

The RT and/or LT modifiers must be used with HCPCS codes A6531, A6532, and A6545 for gradient compression stockings and wraps.

Each item must be billed on two separate lines using the RT and LT modifiers with one unit of service on each line. Claim lines for HCPCS codes requiring the use of these modifiers billed without or on a single claim line will be rejected as incorrect coding.
