Navigating the complexities of wound care coding, especially when it comes to Medicare guidelines, can be challenging for healthcare providers. Accurate documentation is paramount not only for quality patient care but also for ensuring proper reimbursement. This guide serves as your wound care coding companion, specifically focusing on the documentation requirements for procedures related to wound care and potentially relevant to code L37228. Understanding these guidelines is crucial for compliance and optimal patient outcomes in wound management.
Understanding Wound Care Documentation Requirements
Comprehensive and clear medical record documentation is the cornerstone of compliant wound care services. Medicare and other payers require detailed records that justify the medical necessity and appropriateness of the treatments provided. For services potentially related to code L37228 and wound care in general, your documentation must unequivocally demonstrate adherence to coverage criteria and medical necessity guidelines.
At the heart of proper documentation is a certified plan of care. This plan must be meticulously documented within the medical record and should include:
- Treatment Goals: Clearly defined and measurable objectives for wound healing.
- Physician Follow-up: Specification of how and when the physician will monitor the patient’s progress.
- Expected Frequency and Duration of Skilled Treatment: A realistic timeline for the skilled interventions required.
- Potential to Heal: An assessment of the wound’s prognosis and likelihood of healing with the planned treatment.

For ongoing treatment plans, continuous evidence of effectiveness is essential. This necessitates regular and thorough documentation of:
- Diminishing Wound Size: Objective measurements of the wound’s surface area and depth, showing progress over time.
- Resolution of Surrounding Erythema: Documentation of reduced redness and inflammation around the wound.
- Reduction in Wound Exudates: Assessment and recording of decreased wound drainage.
- Decreasing Symptomatology: Patient-reported improvements in pain or other wound-related symptoms.
- Overall Wound Status: A clear and concise assessment of whether the wound is stable, improving, or worsening.
Crucially, the medical record must also demonstrate appropriate modifications to the treatment plan when wounds fail to improve as expected. This proactive approach to adapting care is a key indicator of quality and compliant wound management.
Furthermore, any complicating factors that may impede wound healing, such as underlying medical conditions or infections, must be documented, along with the measures taken to mitigate these factors. This holistic approach to documentation showcases a comprehensive understanding of the patient’s condition and the complexities of wound care. Remember, these medical records must be readily available to Medicare or other payers upon request to substantiate claims.
Key Elements of Wound Care Documentation at Each Visit
To ensure comprehensive and compliant documentation, each patient visit should include clearly recorded evidence of the wound’s response to treatment. This documentation must, at a minimum, incorporate the following elements:
- Current Wound Volume: Precise measurements of the wound, including surface dimensions (length and width) and depth. This provides objective data to track healing progress.
- Presence or Absence of Infection: A thorough assessment for signs of infection, noting the presence and extent of any obvious indicators.
- Necrotic Tissue Assessment: Documentation of the presence (and extent) or absence of necrotic, devitalized, or non-viable tissue within the wound bed. This includes any material that could hinder healing or promote tissue breakdown.

Specific Documentation for Debridement Procedures
When debridement, a common procedure in wound care and potentially relevant to coding scenarios around L37228, is performed and reported, the procedure notes must be exceptionally detailed. These notes should clearly demonstrate:
- Tissue Removal: Specification of the type of tissue removed, such as skin (full or partial thickness), subcutaneous tissue, muscle, and/or bone.
- Debridement Method: The technique used for debridement, for example, sharp debridement, hydrostatic debridement, abrasion, etc.
- Wound Characterization (Pre- and Post-Debridement): A comprehensive description of the wound both before and after debridement. This should include dimensions, a detailed description of necrotic material present initially, and, post-debridement, a description of the tissue removed, including the amount in square centimeters and the degree of epithelialization.
- Severity of Tissue Destruction: Documentation of factors like undermining or tunneling, necrosis, infection, or evidence of reduced circulation, which justify the medical necessity of the debridement procedure.
When reporting debridement for a single wound, it’s crucial to report the depth based on the deepest level of tissue removed. For multiple wounds debrided at the same session, sum the surface area of wounds debrided at the same depth. However, surface areas from different depths should not be combined. Always refer to the current CPT (Current Procedural Terminology) book for the most up-to-date and specific coding guidance.
Active debridement must always be performed under a well-defined treatment plan. This plan should outline specific goals, the anticipated duration and frequency of debridement, the modalities to be used, and a projected endpoint for the treatment. Any deviation from this established plan must be thoroughly documented, explaining the rationale for the change.
For debridement services that exceed utilization guidelines, detailed documentation is even more critical. This documentation must include a complete description of the wound, clear evidence of progress towards healing, any complications that have hindered healing, and a well-reasoned projection of the number of additional treatments deemed necessary.
Addressing Contributory Factors in Wound Healing
Effective wound care documentation extends beyond the wound itself. Appropriate evaluation and management of contributory medical conditions or other factors that can affect wound healing are vital. These factors may include nutritional status, diabetes management, or vascular insufficiency. The medical record should reflect how these conditions are being addressed at intervals consistent with their nature and impact on wound healing.
Photographic documentation is highly recommended, particularly for prolonged or repetitive debridement services. “Before and after” photographs of the wound immediately preceding and following debridement procedures can provide compelling visual evidence of the medical necessity and effectiveness of the treatment. Contractors may request this photographic documentation to support payment of claims, especially for repeated services.
Documentation Requirements for Therapist-Provided Wound Care
When wound care is provided by a therapist, whether in an inpatient or outpatient setting, specific documentation elements are mandatory. These include:
- Practitioner’s Order and Plan of Treatment: A physician’s order for therapy/wound care services and a signed plan of treatment (or plan of care) detailing the treatment modalities must be established as early as possible, ideally within 30 days of initiating treatment.
- Initial Evaluation: Documentation of the therapist’s initial evaluation of the patient’s wound care needs.
- Wound Characteristics: Detailed description of wound characteristics at initial and subsequent evaluations, including diameter, depth, color, and the presence of exudates or necrotic tissue.
- Previous Wound Care Services: A record of any prior wound care services administered, including dates and treatment modalities used.
- Regular Progress Notes: Progress notes documented at least every 10 days, including the current wound status, measurements (size and depth), and the specific treatment provided during that session.
- Instrumentation for Selective Debridement: When selective or sharp debridement is performed, documentation of the instruments used (e.g., forceps, scalpel, scissors, tweezers, high-pressure water jet).
- Certification/Recertification: Documentation of certification or recertification for therapy/wound care services, as required by payer guidelines.
- Time-Based Service Documentation: Accurate records of the actual minutes of service provided to support each timed service or HCPCS (Healthcare Common Procedure Coding System) code billed.
Goal Setting and Documentation in Wound Care
Goals in wound care documentation should adhere to the SMART criteria: Specific, Measurable, Attainable, Relevant, and Time-bound. Documentation related to goals should clearly state the anticipated appearance of the wound upon goal achievement. Progress towards these goals must be consistently documented. Critically, if goals are not being met, the documentation must demonstrate that this issue is being addressed, and the plan of care is being adjusted accordingly. Failure to demonstrate goal-oriented care and plan modification can lead to claim denials.
Utilization Guidelines for Debridement Services
Prolonged or repetitive debridement services necessitate robust documentation justifying the medical necessity for these extended interventions. The medical record must clearly articulate complicating circumstances that reasonably require additional services. For complex debridement involving muscle and/or bone removal, the documentation must unequivocally demonstrate the failure of wounds to improve with less extensive measures.
Coverage for traditional Negative Pressure Wound Therapy (tNPWT) devices and supplies falls under the Durable Medical Equipment (DME) benefit. Providers should consult their specific DME Local Coverage Determination (LCD) for detailed coverage criteria, parameters, and guidelines related to NPWT and potentially code L37228 if applicable.
Continued NPWT is contingent upon ongoing medical necessity and documented evidence of clear benefit from the treatment already provided. The frequency and duration of debridement and NPWT within a palliative treatment plan (when wounds are not expected to heal or in end-of-life care) should be limited and consistent with the principles of palliative care.
The extent and number of services provided must always be medically necessary and reasonable, supported by a documented medical evaluation of the patient’s condition, diagnosis, and plan of care. Services should only continue as long as medical necessity persists and there is demonstrable benefit from the ongoing treatment. Services exceeding anticipated peer norms may be subject to medical review.
Summary of Evidence and Reconsideration for Debridement Coverage
Recent reconsiderations and evidence reviews have led to expansions in coverage for debridement. Debridement is now recognized as medically necessary for stage 2 pressure injuries, diabetic foot ulcers (DFUs), and chronic non-pressure ulcers with limited skin breakdown when biofilm or devitalization is present. This expanded coverage acknowledges that debridement of devitalized tissue, including necrotic tissue, infected tissue, slough, debris, and tissue with abnormal granulation, is a standard and essential component of wound care.

While direct literature specifically on stage 2 pressure injury debridement may be limited, there is a strong clinical consensus supporting its role in wound bed preparation. The National Pressure Ulcer Advisory Panel emphasizes this consensus, citing the ethical challenges of conducting randomized controlled trials directly comparing debridement to no debridement in humans. However, ample evidence supports debridement for ulcers with biofilm or devitalized tissue, regardless of stage.
Similarly, debridement has long been accepted as a standard practice for DFUs. Reconsiderations have further clarified coverage for DFUs beyond neuroischemic ulcers, recognizing that diabetic foot wounds can arise from various etiologies, including deformity, limited ankle range of motion, trauma, and other factors. Evidence consistently demonstrates that debridement enhances DFU healing when combined with standard wound care.
