Coverage Criteria for Severe Malnutrition
Documentation and clinical criteria for severe malnutrition
Severe malnutrition diagnoses are validated against objective clinical criteria and must be clearly documented in the inpatient medical record by the physician or a licensed independent practitioner. ALL of the following criteria must be met for reimbursement.
Anthropometric criteria (ONE of)
- Adult: BMI meeting policy-specified threshold (see record).
- Pediatric: BMI-for-age Z-score, length/height-for-age Z-score, weight-for-height Z-score (WHZ), or length Z-score > 3 standard deviations below the median.
- Mid-upper arm circumference (MUAC) ≤ 11.5 cm or > 3 standard deviations below the median (where applicable).
Evidence of inadequate intake or weight loss (ONE of)
- Unintended weight loss meeting thresholds (examples): >2% in 1 week; >5% in 1 month; >7.5% in 3 months; >10% in 6 months; >20% in 1 year; current body weight ≤ 70% of usual body weight or ≤ 70% of ideal body weight.
- Decreased energy intake: <75% of estimated energy requirement for ≥1 month; or intake <25% of estimated energy/protein needs in applicable age groups.
- Neonatal-specific intake/velocity criteria: e.g., <23 months with 25% of expected weight gain (reduced weight velocity); decline in weight-for-age or length-for-age Z score > 2 SD; weight or linear growth velocity ≤ 25% of expected; or 7 consecutive days of protein/energy intake providing <75% of estimated needs (age-specific as listed in policy).
Physical findings (ALL or as specified)
- Documented severe muscle wasting or severe loss of subcutaneous fat.
- Documented severe fluid accumulation (edema) attributable to severe malnutrition, where applicable.
- Measurable and reduced grip strength, when measured and recorded.

Provider Responsibilities, Audits, and Payment Determinations
Post-pay audit: medical record request, determination letter, and dispute instructions
When a potential billing error is identified, the Health Plan will request the medical record to validate the diagnosis and procedure codes billed on the claim; certified professional coders and registered nurses will clinically validate documentation. The Health Plan will send a determination letter to the provider with a thorough explanation of the determination and instructions for submitting a dispute. Clinical validation reviews are completed within 30 days of receipt of medical records.
- Health Plan uses claims data and a proprietary clinical algorithm to identify claims for retrospective audit.
- Medical record will be requested when a potential billing error is identified to validate billed diagnosis/procedure codes.
- Clinical validation performed by certified coders and RNs; review overseen by the Health Plan Medical Director.
- Provider determination letter will explain the decision and provide dispute submission details.
- Clinical validation review completed within 30 days from receipt of medical records.
Provider responsibility and limits of policy for payment determinations
Providers must exercise professional medical judgment and are solely responsible for the medical advice and treatment of members; this payment policy is guidance only and does not guarantee payment. Payment determinations are subject to the member's coverage documents and applicable state and federal requirements.
- This payment policy is a guide to payment and does not constitute a contract or guarantee of payment.
- Coverage and payment determinations are subject to all terms, conditions, exclusions and limitations of the member's coverage documents and to state and federal requirements.
- Providers are independent contractors, not agents or employees of the Health Plan.
Precedence: state Medicaid and Medicare NCD/LCD review
State Medicaid coverage provisions take precedence over this payment policy when conflicts exist; for Medicare members, review all applicable National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs) to ensure consistency with this policy's criteria.
- For Medicaid members/enrollees, state Medicaid provisions override this payment policy where conflicts exist; refer to the state Medicaid manual for applicable coverage provisions.
- For Medicare members/enrollees, review applicable NCDs and LCDs before applying the criteria in this payment policy.
Definitions and Terminology
OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
