Molina Healthcare Claim Denials

Overview

Molina Healthcare operates Medicaid managed care plans in 20+ states. Denial patterns follow state Medicaid rules, so the same service may be denied in one state and covered in another. The most common Molina denial codes are CO-197 (no prior auth), CO-50 (non-covered), and CO-29 (timely filing).

Key Requirements

  1. Always check the member's state plan for covered benefits before billing.
  2. Obtain prior authorization for services on the state-specific PA list.
  3. Submit claims within the state's timely filing deadline (varies: 90-365 days).
  4. Use the Molina provider portal at molinahealthcare.com for eligibility, auth, and claim status.
  5. Dual-eligible members: bill Medicare first, then submit to Molina as secondary.
