Q: What if Thiola isn't on Humana's formulary? A: You can request a formulary exception through Humana's coverage determination process. Your doctor must provide a supporting statement explaining why formulary alternatives aren't appropriate.

Q: Can I request an expedited appeal in Michigan? A: Yes, both Humana and Michigan DIFS offer expedited reviews when delays could seriously jeopardize your health. Your physician must document the medical urgency.

Q: Does step therapy apply to Thiola? A: Humana typically requires documentation that conservative measures (hydration, alkalinization) have been tried before approving Thiola, but formal step therapy through other medications may not apply given Thiola's specialized indication.

Q: What's the difference between Thiola and Thiola EC? A: Thiola EC is an enteric-coated formulation that may improve gastrointestinal tolerability. Both contain tiopronin and have similar coverage requirements, though your doctor may need to specify why the EC formulation is preferred.
