Pittsburgh medical billing company: the UPMC and Highmark split

Timely filing in Pittsburgh

Major payers

Does a Highmark member have in-network access to UPMC in Pittsburgh?

It depends on the Highmark product, not on the insurer's name. UPMC states that Highmark members with broad-network commercial or Medicare Advantage plans, which it calls the majority of Highmark members, have full in-network access to UPMC hospitals, doctors and services, while members with narrow-network commercial plans and narrow-network Medicare Advantage plans have limited in-network access.

UPMC also says patients whose plans give full in-network access pay no more out of pocket at UPMC than at any other hospital, and that it accepts most major insurers, naming Aetna, Cigna, Highmark, UnitedHealthcare and UPMC Health Plan. For a Pittsburgh biller the lesson is plain: a Highmark card is not enough to know whether a UPMC visit is in network.

A narrow-network Highmark member at a UPMC facility may be an out-of-network patient for that facility. If so, the claim can fall under the federal No Surprises Act for emergency care or for out-of-network professionals at an in-network facility, instead of a contract rate. Confirm the product code at scheduling with eligibility verification, and keep a record of what the payer portal returned that day.

UPMC gives patients a help line for network questions, 1-855-646-8762. This page does not predict whether the arrangement between the two systems will change; UPMC's statement is the one to check.

How should an ER group in Pittsburgh handle Highmark members at a UPMC hospital?

Bill by the member's product, not the hospital. If the member's Highmark plan has full access to UPMC, the claim follows the group's contract with Highmark; if it is a narrow-network product, the group should read the claim as potentially out of network and keep emergency documentation ready, since the federal rules for emergency services apply at any hospital, in or out of network.

The Pennsylvania Insurance Department's No Surprises Act page says the Act requires emergency services at a hospital, hospital outpatient department, ambulatory surgical center or by air ambulance to be covered without prior approval, whether or not the provider or facility is in network, and that ground ambulance services are not currently covered by the Act. It also says patients whose in-network facility uses an out-of-network provider such as the lab or pathologist must be covered at the in-network rate.

Our out-of-network billing and IDR work picks up when payment comes in low: open negotiation first, then federal IDR where it applies. Pennsylvania's own rules, including what the state does and does not add, sit on the Pennsylvania page and in our state surprise billing laws guide.

Which Medicaid plans pay Pittsburgh claims?

Allegheny County is in the Southwest zone of HealthChoices, Pennsylvania's Medicaid managed care program, so a Pittsburgh claim goes to one of the plans the Department of Human Services lists for that zone. The DHS Pennsylvania Medicaid Managed Care Directory, updated September 2026, lists Allegheny with 13 other counties in the Southwest zone: Armstrong, Beaver, Bedford, Blair, Butler, Cambria, Fayette, Greene, Indiana, Lawrence, Somerset, Washington and Westmoreland.

The directory gives separate provider services numbers: 800-392-1147 for Highmark Wholecare and 866-918-1595 for UPMC for You. Medicaid plan limits for timely filing come from each plan's own manual, and the 180-day Medical Assistance fee-for-service rule is covered on the Pennsylvania page and in our Medicaid guide.

What are Highmark's timely filing rules for a Pittsburgh provider?

Highmark's provider manual sets 365 days from the last date of service in Pennsylvania when your contract is silent. The manual's timely filing policy says any claim not submitted and received within the time frame in your contract is denied for untimeliness, and that if the contract has no limit, claims must be received within 365 days of the last date of service in Pennsylvania and West Virginia, unless the member's policy provides a different period.

When Highmark is the secondary payer, the manual requires the claim to carry an explanation of benefits from the primary payer. It also says that if a claim denies for timely filing and you previously submitted within 365 days, you should resubmit with the denial and your appeal. For appeal levels, corrected claims and common denials, use our Highmark billing guide; Medicare Advantage rules are on the Medicare Advantage page.

Which Pittsburgh systems and trauma centers should a biller know?

Two Pittsburgh hospitals are accredited Level I adult trauma centers by the Pennsylvania Trauma Systems Foundation, according to the Foundation's own pages: UPMC Presbyterian at 200 Lothrop Street and AHN Allegheny General Hospital at 320 E North Ave. Both are in the City of Pittsburgh.

Allegheny Health Network's own site lists hospitals in the Pittsburgh area including Allegheny General Hospital and West Penn Hospital in the city, Jefferson Hospital and Canonsburg Hospital in the South Hills, Forbes Hospital and Allegheny Valley Hospital in the eastern suburbs, and, in the North Hills, AHN Beaver Hospital, AHN Sewickley Hospital and Wexford Hospital. It also lists Brentwood, Harmar, Hempfield and McCandless Neighborhood Hospitals.

Why this matters for claims: a group that covers several of these sites should map each location to its billing entity and NPI before submitting, and should not assume a neighborhood hospital bills like the main campus. Highmark Health's own About page names Allegheny Health Network as an affiliate. Treat plan and system questions as separate contracts anyway.

Which Pennsylvania agency handles surprise bill complaints for Pittsburgh patients?

The Pennsylvania Insurance Department runs a No Surprises Act page for consumers and providers, and points patients who get a surprise bill to its Request a Review of an Unexpected Medical Bill service. The page also says the Act requires certain providers and facilities to give patients disclosure information on the billing requirements, limitations and exclusions that apply to them.

The department publishes a No Surprises overview, overviews for health plans and for providers, and a model disclosure notice. A Pittsburgh facility writing or updating its notice should start with the provider overview and the model notice on that page, then have counsel review the final text. Patients on self-funded employer plans may have other routes; the Pennsylvania page covers how the state and federal pieces fit.

How we handle billing for Pittsburgh groups and facilities

We work with Pittsburgh hospitals, emergency departments, urgent care networks and large groups remotely, and we have no office or staff in Pittsburgh. Our US registered office is in Richmond, KY, and our team works from Vancouver, BC, Dubai, UAE and Islamabad, PAK.

For network-split work we start with automated eligibility checks, so the product is confirmed before the claim goes out. Claims leave within 24 hours of charge entry and denials are worked within 48 hours. When a claim ends up out of network, we run open negotiation and dispute submissions end to end under federal IDR and applicable state pathways, with deadline management and documentation checks.
