Summary

IHCP (Indiana Medicaid) is fixing a system issue where enrolled billing providers with Type 1 NPIs were incorrectly being denied when listed as attending providers on institutional claims. Until the system fix is complete, providers can dispute these denials by submitting documentation showing they have an active Type 1 NPI.

Action Required

Action needed
Immediately: If your institutional claims (inpatient, outpatient, ASC, LTC) are being denied due to attending provider NPI issues, submit an administrative review or dispute. Include documentation from NPPES NPI Registry showing the provider has an active Type 1 NPI on the date of service, plus a copy of bulletin BT2025142. Billing team should monitor for these specific denial patterns and be prepared to appeal with proper documentation.
