Summary
Nevada Medicaid implemented new error code 6151 that will automatically deny claims when providers bill new patient visit codes for recipients who have been seen by the same provider or group practice within the past three years. Providers must now use established patient codes instead of new patient codes in these situations.
Action Required
Immediately: Billing team must update system edits to track patient visit history within three years per provider/group practice. Configure billing software to flag potential new patient code usage when recipient has prior visits with same provider or group within 36 months. Train staff to verify patient history before coding visits as 'new patient' to avoid error code 6151 denials. Update encounter forms and coding guidelines to remind providers to use established patient codes when appropriate.
