Cardiology Medical Billing Services in Montana

Fee-for-service Medicare claims from Montana are processed by Noridian Healthcare Solutions as the A/B MAC for Jurisdiction F, which also covers Alaska, Arizona, Idaho, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming. CMS re-awarded that contract to Noridian in August 2025, with the new contract taking effect September 1, 2025. For a cardiology practice, the jurisdiction matters more than most administrators expect. Local coverage determinations and billing articles published for JF are what govern coverage of echocardiography, stress testing, ambulatory monitoring and vascular studies for your Medicare population, and JF's documentation expectations are what an appeal has to satisfy. DMEPOS items furnished to Montana beneficiaries go to Noridian's DME MAC Jurisdiction D instead, which is a different portal, a different set of policies and a different appeals path.

The commercial picture is thin and currently in motion. Blue Cross and Blue Shield of Montana, part of Health Care Service Corporation, is the state's largest individual-market carrier, with Mountain Health CO-OP and PacificSource Health Plans making up the rest of the marketplace. In May 2026, PacificSource announced it is leaving Montana entirely rather than just exiting the individual market: individual, small group, large group and Medicare Advantage business, with coverage continuing through the end of 2026 and member notices going out 180 days ahead of each end date. Figures provided to the Montana Commissioner of Securities and Insurance put its Montana book at roughly 11,000 individual, 15,000 small group, 4,500 large group and 1,100 Medicare Advantage members.

Montana Medicaid, branded as Montana Healthcare Programs, is one of the few remaining state programs that runs primarily on fee-for-service rather than contracting cardiology risk out to managed care organizations. That has a specific consequence: there is no MCO to argue with, but there is also no MCO provider representative to escalate to. Claims move through the state's MMIS with Conduent as fiscal agent, and coverage, authorization and pricing questions come back to the state's manuals and fee schedules.

Physician payment is built on RBRVS. The state multiplies Medicare relative value units by a Montana Medicaid conversion factor and a policy adjuster; the conversion factor published on the January 1, 2026 physician fee schedule is $45.41 for fiscal year 2026. Fee schedules are reissued in January and July with the state fiscal year rate update, which is a different cadence than the annual Medicare update most billing calendars are built around. Per-code indicators matter for cardiology: separate pricing for modifier 26/TC, global surgery indicators, multiple-surgery and bilateral flags.

• Prior Authorizations: Mountain-Pacific Quality Health manages reviews for cardiac rehabilitation, pulmonary rehabilitation, out-of-state inpatient rehab, advanced heart failure transplants, and physician-administered drugs (e.g., inclisiran, evinacumab).
• Program Updates: The Passport to Health primary care case management program ended June 30, 2026 and was replaced by Primary Care Montana. Claims for dates of service after June 30 no longer need a Passport referral ID, but older claims still do.
• Medicaid Expansion Churn (H.R. 1): Six-month renewals and community engagement requirements create patient coverage churn during serial procedures (e.g., 36-session cardiac rehab, device clinic schedules, or heart failure titration series). Verifying eligibility per visit is critical.
• Line vs. Header COB: Traditional Medicare coordination of benefits is processed at the claim line level on CMS-1500, while Medicare Advantage and commercial TPL are processed at the header level. Mixing line and header COB on multi-line cardiology claims forces manual adjustments.

Roughly 45 percent of Montanans live outside metro areas, and the state operates about 50 critical access hospitals (CAHs) along with dozens of rural health clinics (RHCs). Cardiology reaches those communities largely through outreach: a cardiologist from Billings, Missoula, Great Falls or Kalispell holds clinic in a small town on a set day each month, using local hospital space and equipment.

That model creates billing questions general billers get wrong. When the hospital owns the equipment and employs the tech, the practice bills the professional component with modifier 26 and the facility bills the technical component (TC); billing globally in that setting invites a duplicate denial against the facility's TC claim. Place of service and service facility location must reflect where the service occurred, not the practice's main office, and each location must be enrolled correctly.
