Summary
NC Medicaid expanded coverage for sleep studies and polysomnography services effective July 1, 2026, adding new diagnosis criteria (Restless Legs Syndrome, Chronic Insomnia, Snoring with specific symptoms, neuromuscular disorders with sleep symptoms) and removing prior authorization requirements for unattended home sleep tests. Facility-based sleep studies are now covered when home equipment is unavailable or cannot be operated. All claims must include documentation of Clinical Coverage Policy 1A-20 criteria.
Action Required
By June 30, 2026: Billing team must update all NC Medicaid claim submission workflows to reflect the removal of prior authorization requirements for unattended home sleep tests. Providers and clinical staff must update encounter forms and EMR templates to document medical necessity criteria per sections 3.1-3.4 of Clinical Coverage Policy 1A-20 for all sleep study orders, including the newly covered conditions (Restless Legs Syndrome, Chronic Insomnia, Snoring with specified symptoms, and neuromuscular disorders with sleep symptoms). Billing team must audit historical denials for unattended home sleep tests dated after July 1, 2026 and resubmit if applicable. Update internal policies to clarify that facility-based polysomnography is now covered when home equipment is unavailable or patient cannot operate equipment. Contact NC Medicaid Contact Center at 888-245-0179 with implementation questions. Failure to include required clinical documentation will result in claim denials.
