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.

Traditional negative pressure wound therapy (NPWT) devices, units, and supplies are covered under the Durable Medical Equipment (DME) benefit when they meet DME LCD coverage criteria and medical necessity.
CPT codes 97597, 97598, and wound debridement codes 11042-11047 may be covered when the medical record documents medical necessity consistent with L37228 Wound Care criteria and Medicare reasonable-and-necessary requirements.
CT or MRI scans of the head or neck are covered when the medical record documents the scan is reasonable and necessary for diagnostic evaluation.
Coverage requires documentation supporting clinical indication such as history and physical exam findings, laboratory results, and signs or symptoms that justify the diagnostic test.
Initial lumbar MRI is covered when the test is medically reasonable and necessary and the medical record documents clinical rationale and supports the ICD-10-CM code(s) billed.
