Medical Billing Services in Montana

Montana practices work across distances most states never deal with. A family practice in Great Falls and a therapy office in Bozeman may serve patients who drove two hours to get there, and the billing behind those visits runs through a state Medicaid program that looks different from most of the country: Montana never handed its program to managed care companies. Between that program, Medicare, and the commercial plans patients carry, a small Montana team is expected to know several rulebooks cold — usually while also running the front desk.

Fastora Medical Billing Solutions carries that workload for Montana practices, from solo offices to growing regional groups, as part of our medical billing services across the United States. This page covers how Montana’s fee-for-service Medicaid program actually works — including a 2026 program change that altered referral habits midstream — and what we take over so the work stops depending on whoever has a spare hour.

Billing problems Montana practices run into

The first is that there is no plan playbook to fall back on. In managed care states, a biller learns each plan’s rules; in Montana, Medicaid rules come from the state’s own manuals and provider notices, and they reward close reading. The program also changed shape recently: a primary care restructuring that took effect in mid-2026 retired familiar programs and the referral routines attached to them. Practices still working from last year’s habits — still collecting a referral number that is no longer required, or unsure whether it is required at all — lose time on every claim, and occasionally lose the claim.

The second is arithmetic of a different kind: very small teams covering very large areas. When one person handles scheduling, intake, eligibility, and billing, follow-up work is what slides. Denials wait, receivables stretch, and because Montana’s filing clock keeps running the whole time, delay converts directly into write-offs. None of it arrives as a crisis. It accumulates quietly until a quarter’s worth of earned revenue has aged past recovery.

Montana Medicaid: fee-for-service, run by the state

Montana’s Medicaid program operates as Montana Healthcare Programs, administered by the Department of Public Health and Human Services (DPHHS). Unlike most states, Montana has no comprehensive risk-based managed care program for Medicaid. The state pays providers directly under its fee schedules, with a primary care case management overlay on top — a structure that makes the state’s own rules, not a plan’s, the ones that matter.

That overlay changed on July 1, 2026, when Primary Care Montana (PCMT) began. The programs it replaced — Passport to Health, the Patient-Centered Medical Home program, and Comprehensive Primary Care Plus — ended on June 30, 2026. The most concrete billing effect: a Passport referral ID number is no longer required for dates of service after June 30, 2026, though it was required for earlier dates — and billing habits built over years of Passport do not update themselves.

Medicaid expansion in Montana runs through the HELP Plan, administered mostly through Blue Cross and Blue Shield of Montana acting as a third-party administrator — an administrator, not a managed care organization — with some services handled through Conduent, the state’s claims contractor. Conduent also processes claims and handles provider enrollment and inquiries, and providers work through the Montana Access to Health (MATH) Web Portal. One enrollment rule is absolute: the program pays only enrolled providers, so enrollment is not a formality to catch up on later — it is the precondition for every dollar. Our credentialing and payer enrollment support keeps enrollments and provider records current so claims are never held up by an administrative gap.

Montana’s filing rule rewards practices that understand its details. Under the state’s timely filing limits (ARM 37.85.406), clean claims must be submitted within twelve months of whichever is later: the date of service, or the date retroactive eligibility or disability is determined. Claims tied to a Medicare decision or a third-party adjustment run on a six-month clock from that payer’s notice instead. The state expects every problem with a claim to be resolved inside that same twelve-month period — which means a denial received in month ten leaves little room for a slow appeal.

Charge review that catches errors while they are cheap

In a fee-for-service state, the payer’s edits are unforgiving in a specific way: the claim either matches the documentation and the program’s requirements, or it comes back. A therapy session billed in units the note does not support, a substance abuse service coded at the wrong level of care, a missing modifier — each is a denial that takes weeks to surface and longer to fix. Fastora reviews charges against the visit documentation before claims are submitted, so the correction happens at the one moment it costs almost nothing. It is the practical core of what medical billing and coding services in Montana should mean: the coding and the claim built together and sent right.

What Fastora handles for Montana practices

Our medical billing services span the full cycle, and Montana practices engage us for the whole of it or for the stages their small teams cannot absorb:

• Eligibility verification. Coverage is confirmed ahead of the appointment — including retroactive eligibility situations, which matter in Montana because the filing clock can run from the eligibility determination date.
• Charge entry and claim submission. Claims are built from reviewed charges, scrubbed for common errors, and submitted electronically to the state program, Medicare, and commercial payers.
• Authorization management. Required approvals are requested and tracked against the claim, so services are not denied over a missing authorization.
• Denial follow-up and appeals. Denials are categorized by cause, corrected where the record supports it, and appealed with time to spare inside the state’s resolution window.
• Receivables follow-through. Unpaid and aging claims are worked on a schedule — oldest and largest first — instead of whenever the office finds a gap in the day.
• Posting and reconciliation. Payments are posted line by line, surfacing underpayments where a payer paid below its own terms.

That work is backed by 5+ years of experience, 50+ active clients, and 100+ satisfied MDs served. Montana practices choose between two arrangements — a percentage of collections or a flat monthly fee — with the fit turning on claim volume and how much of the billing workload moves to us.

Specialties we support in Montana

Behavioral health. Behavioral health is the largest outpatient need in much of Montana, delivered by practices that are often small, spread out, and billing the state program, Medicare, and commercial plans in the same week. Our behavioral health billing services handle the authorization and documentation discipline that work requires, with workflows built for repeat visits and ongoing care.

Substance abuse treatment. Substance use programs bill services where level-of-care documentation and authorization carry unusual weight, and where a coding mismatch denies the whole claim rather than part of it. Our substance abuse billing support is structured around those documentation demands and the recurring approvals treatment plans require.

Family practice. Family practices are the backbone of Montana care, carrying the widest payer mix and the broadest service range of any specialty in the state. We give them a single, consistent billing operation across every payer they accept.

Physical and occupational therapy. Therapy billing succeeds on unit counting, modifiers, and visit limits applied correctly across an entire caseload. Because therapy patients return weekly, one billing error repeats on every visit until someone catches it — our charge review exists to catch it on the first claim, not the fifteenth.

Billing support across Montana

Billings

Billings is Montana’s largest city and the referral center for a region that reaches into Wyoming and the Dakotas, with major hospital systems and a deep independent practice community. Billing here means volume across every payer type, and the discipline that volume demands: consistent eligibility checks, clean submission, and follow-up that does not depend on one person’s memory.

Missoula

Missoula anchors healthcare for western Montana, mixing hospital-affiliated groups with a strong community of independent behavioral health, therapy, and family practices. Many run experienced but small administrative teams. Our role is to absorb the work those teams cannot reach — denial queues, aging receivables, enrollment upkeep — so in-house staff can stay with patients.

Great Falls

Great Falls serves north-central Montana, where practices draw patients from a wide agricultural region and operate with lean back offices. When the same staff handle intake and billing, receivables work is what gets postponed. We take the billing side over, so denials and aging claims stop competing with the waiting room for attention.

Bozeman

Bozeman is one of Montana’s faster-growing communities, and its practices are growing with it — new providers, new locations, new payer contracts. Growth creates credentialing and enrollment work that has to be finished before claims can pay. We keep those foundations current while handling day-to-day billing for expanding Bozeman practices.

Helena

As the state capital, Helena’s practice community serves the city and the surrounding counties, with family practice, behavioral health, and therapy well represented. Smaller teams are the norm, which makes a dedicated billing partner the difference between claims that get worked and claims that age quietly toward the filing deadline.

Frequently asked questions

Montana Medicaid is not managed care. What does that change about billing?

It changes who sets the rules. There is no managed care organization standing between your practice and the state: Montana Healthcare Programs pays providers directly under its fee schedules, claims are processed through the state’s contractor, and the program’s own requirements — enrollment, documentation, and the timely filing limits in ARM 37.85.406 — decide whether you are paid.

Do we still need a Passport referral ID on our claims?

Not for current dates of service. The Passport to Health program ended June 30, 2026, and Primary Care Montana began the next day; a Passport referral ID is no longer required for dates of service after June 30, 2026. It was required for earlier dates, so claims for services before that line still follow the old rule — a distinction we apply claim by claim during the transition period.

What is Montana’s Medicaid filing deadline?

Clean claims must reach the program within twelve months of the later of the date of service or the date retroactive eligibility or disability was determined. Claims following a Medicare or third-party decision run six months from that payer’s notice.

How much do medical billing services cost in Montana?

We price two ways: a percentage of collections, or a flat monthly fee. Which fits better depends on your claim volume and how much of the cycle you want off your team. Start with the free billing audit — it shows your current denial and receivables picture before you choose a model.

Can you help with provider enrollment?

Yes — and in Montana it matters more than most places, because the program pays only enrolled providers. We manage enrollment and provider record upkeep with the state program and your commercial payers, and we track the renewals and changes that keep claims from being held up by an administrative gap.

Our office manager handles billing now. Can Fastora take only part of it?

Yes. Many Montana practices keep routine submission in-house and hand us the work that demands persistence: denial appeals, aged receivables, eligibility checks, and authorization tracking. The arrangement is defined around your team’s capacity and can expand or contract as your practice changes.

Start with a free billing audit

If billing in your Montana practice depends on whoever has time — or the 2026 program changes left your workflows half-updated — a free initial billing audit is the clearest first step. We will review how your claims are performing, pinpoint where denials and aging receivables are costing you, and lay out what fixing them would involve, with no obligation. Request your free initial billing audit and we will take it from there.
