Identify the claim payer for the service date
Check eligibility and the responsible program before submitting a claim. IHCP’s claim submission module distinguishes FFS processing from managed care instructions. Our recommended claim worksheet records the member’s assignment, service, clinician, billing entity, location, and authorization questions before submission.

Submit applicable FFS nonpharmacy claims through PHP
PHP supports professional, institutional, and dental FFS nonpharmacy claims, claim searches, and payment history with remittance information. Use the appropriate claim transaction for the provider and service. These state functions do not replace the responsible MCE’s claim instructions.

Match the rendering NPI to the actual arrangement
The behavioral health module distinguishes enrolled practitioners billing with their own rendering NPI from qualified practitioners billing under an enrolled supervising practitioner’s NPI. Our recommendation is to confirm enrollment, scope, and the permitted arrangement before selecting an NPI or modifier.
Behavioral Health Services reference module, September 2026
Apply the April 2026 supervising-NPI modifier guidance
BT202655 requires HE for LCSW, LMFT, and LMHC services billed under a supervising practitioner’s NPI. Licensed psychologists, including licensed independent school psychologists, use AH in that arrangement, retroactive to January 1, 2025. The bulletin applies to both FFS and managed care claims.

Do not carry those practitioner modifiers into MRO
BT202635 says MRO claims must not report modifiers identifying the rendering practitioner’s qualifications. Keep the MRO service policy separate from the outpatient practitioner rule. Other service-specific claim requirements still need review.

Check the covered code and documentation
The IHCP Code Sets page links maintained provider code tables and explains that updates are announced in bulletins. Check the Behavioral Health Services Codes and the relevant service module for the actual service. Our suggested pre-submission review also checks documentation, authorization, and telehealth requirements where relevant.

Investigate before correcting or resubmitting
Use the Claim Adjustments module for the applicable FFS adjustment process and the MCE’s instructions for its claims. Our recommended follow-up record keeps the claim reference, payer response, reason for correction, and next action together, so the biller can distinguish an adjustment from an appeal.

Frequently Asked Questions
Does every Indiana Medicaid mental health claim go through PHP?
No. PHP’s FFS claim functions do not replace MCE instructions for managed care claims.
Does HE apply to every therapy claim?
No. The cited rule concerns services billed under a supervising NPI and excludes MRO. Other claim arrangements require their own review.
Does the supervising-NPI psychologist rule use HE?
BT202655 requires AH for licensed psychologists in that arrangement.
