Summary
Illinois Medicaid providers must select ALL correct specialty/subspecialty combinations in a single IMPACT system enrollment application. Creating separate enrollments for each specialty generates multiple provider ID numbers that cause claim rejections.
Action Required
Immediately: Billing team must review current IMPACT enrollment to ensure all specialties/subspecialties are listed under one application. If multiple provider ID numbers exist, submit modification through IMPACT system to consolidate into single enrollment. Contact IMPACT Help Desk at IMPACT.Help@Illinois.gov or (877) 782-5565 for assistance. Failure to correct will result in continued claim rejections.
