Summary
This is a comprehensive thyroid studies policy (L.2.04.416) that establishes medical necessity criteria for thyroid function testing. The policy allows up to 2 thyroid tests per calendar year for stable patients, with more frequent testing permitted when therapy is altered or symptoms are present.
Action Required
Immediately: Review current thyroid testing frequency to ensure compliance with 2-tests-per-calendar-year limit for stable euthyroid patients. Billing team should verify medical necessity documentation supports testing frequency, especially for patients requiring more than 2 tests annually. Update prior authorization processes to flag cases exceeding frequency limits without documented therapy changes or symptoms.
