ICD-10-CM
Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- 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.
Key Coverage Criteria
- 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.
- Incision and drainage (I&D) is covered when medical record documents an abscess, hematoma, seroma or other collection of the skin/subcutaneous/accessory structures requiring drainage with signs/symptoms that justify the procedure (e.g., evidence of infection, frank pus, severe pain, or failure of conservative measures).
- For podiatry (specialty 48), CPT codes 10060, 10061 or 10160 are payable when billed with ICD-10-CM codes L02.611, L02.612 or L98.8 only.
- CPT code 10140 is payable only when billed with the specified ICD-10-CM codes listed in the policy (multiple S- and L- codes for traumatic or specific skin conditions as enumerated).
