Pennsylvania Medicaid (PA HealthChoices) divides the state into 5 health zones, each with different plans — UPMC for You, Geisinger, Aetna Better Health, and Keystone First are the major ones. Pennsylvania has strict balance billing protections under Act 68 that affect how out-of-network disputes are handled. Timely filing is 180 days for most payers.
Pennsylvania is the land of provider-owned payers: UPMC Health Plan and Geisinger Health Plan compete with two separate Blues — Highmark in the west and Independence Blue Cross in the southeast — that divide the state geographically. Medicaid's HealthChoices program is zone-based, so plan availability depends on region. Payer-provider vertical integration creates network dynamics unlike any other state.
Administered by the PA Department of Human Services (DHS). The patient's plan assignment — not just Medicaid eligibility — determines the portal, prior-auth list, and filing rules that apply.

Initial-claim windows for the payers Pennsylvania practices bill most. Commercial limits are contract-specific — always confirm against your provider agreement and the payer's current manual.
Verified against payer publications at time of writing (July 2026). Filing limits change by contract and plan year — treat this table as a starting point, not a substitute for the payer manual. See our methodology.
Highmark (west) and Independence (southeast) are separate companies. Statewide groups maintain two Blue contracts, two portals, and two fee schedules.
UPMC and Geisinger are both your competitor (as health systems) and your payer. Network participation decisions carry strategic weight beyond ordinary contracting.
Medicaid plan availability differs by HealthChoices zone; multi-county practices may bill different MCO sets for identical services.
PA Medicaid behavioral health runs through county-based BH-MCOs, separate from physical health plans — a completely parallel billing infrastructure.
