The medical record must clearly document that the coverage indications, limitations, and medical necessity criteria in L37228 Wound Care have been met for any billed wound care item or service.
Documentation must support the specific CPT/HCPCS code(s) billed, including procedure details, depth and surface area for debridement codes, and rationale for the service.
When hydrotherapy (whirlpool) is billed with CPT 97597 or 97598, the record must state why hydrotherapy was necessary to remove devitalized/necrotic tissue and that a therapist's skill was required to perform the service.
If CPT 97597 or 97598 is billed by a therapist while the patient is under a Home Health benefit, coverage depends on inclusion in the Home Health plan of care; if billed by a physician or non-physician practitioner it is paid under Part B even if the beneficiary has an active Home Health plan.
