HCPCS Code A6549: Gradient Compression Garment, Not Otherwise Specified

The narrative field in the claim form provides detailed information supporting the medical necessity and fitting of the compression garment. Properly completing this field helps clarify the patient’s condition and the justification for the device, which is critical for claim approval.

When billing for bilateral compression stockings, use appropriate LT modifiers for the left limb and RT modifiers for the right limb. If a single claim line cannot accommodate both, submit separate claim lines with modifiers to indicate which limb the item corresponds to, ensuring accurate processing.

LT modifiers designate left-sided items, while RTLT modifiers indicate items that cover both right and left sides. Using these modifiers correctly on claims helps payers identify the specific limb(s) treated and prevents payment errors.
