Summary
Illinois updated their Pharmacy Services Handbook with four key changes: prescriber NPI is now required on all pharmacy claims, ostomy supplies are no longer billed through the Pharmacy Program, Plan B prescription age limits were revised, and new language was added for Plan B verbal prescriptions.
Action Required
Immediately: Billing team must ensure prescriber NPI is included on all pharmacy claims. Stop billing ostomy supplies through the Pharmacy Program - these should now be billed as standard DME. Review updated Plan B prescription requirements for age limits and verbal prescription protocols.
