2025 HCPCS code AW
Modifier AW is used with HCPCS codes to identify supplies associated with a surgical dressing.
Medical necessity for the surgical dressing and associated supplies must be documented. The documentation must demonstrate that the supplies were necessary for the treatment of the patient's condition.
In simple words: Modifier AW is used with codes for surgical dressing supplies, like bandages, to show they were used with a surgical dressing.
This modifier is appended to HCPCS codes that a provider reports for supplies associated with a surgical dressing, meaning a sterile bandage or compress applied to a wound to encourage healing and to prevent infection.
Example 1: A physician applies a surgical dressing and uses sterile gauze pads, reported with a HCPCS code and the AW modifier., A patient receives a surgical dressing kit for home use, including bandages and antiseptic wipes, which are coded with the AW modifier., During a surgical procedure, a specific type of surgical tape is used and reported with the appropriate HCPCS code and the AW modifier.
Documentation should support the use of the surgical dressing and the associated supplies. The medical record should clearly indicate the type of supplies used and their purpose.
