NICU Level Coverage Criteria

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Coverage criteria tied to MCG guidelines

Claims for NICU services must be supported by documentation that satisfies the level of care criteria per MCG guidelines; continued stay authorizations are reviewed against MCG Intensity of Care Guidelines.

Documentation and review: Claims must include clinical documentation establishing the level of care/revenue code has been satisfied; the Plan may request supporting documentation and may review inpatient admissions to ensure proper duration and level of care.
