Remote billing built around two separate systems

Medical Billing Services in North Dakota & South Dakota

Two states, two workers' comp systems, two licensure timelines, and one shared border. A2Z Billings staffs for how North Dakota and South Dakota actually differ, instead of treating "the Dakotas" as a single combined market.

What changes at the state line

1 of 4 North Dakota is one of only four states in the country with a monopolistic workers' comp fund, so every workplace injury claim runs through the state's own program.
44 states Interstate Medical Licensure Compact members, a list that includes both North Dakota and South Dakota.
75 Combined Critical Access Hospitals across the two states: 36 in North Dakota, 39 in South Dakota.
6Combined Indian Health Service hospitals serving the region: 2 in North Dakota, 4 in South Dakota.

North Dakota and South Dakota share a border, a Medicare contractor, and a fairly small population base, but very little else runs the same way on the compliance side. A workers' comp claim filed in Bismarck goes through a completely different payer than the same claim filed in Sioux Falls. A physician whose license clears both state medical boards through the Interstate Medical Licensure Compact still has to be credentialed separately with every payer the practice bills. A2Z Billings is headquartered in Michigan and supports providers across both states remotely, with a team that treats North Dakota and South Dakota as two distinct billing environments rather than one combined region.

State by state

The differences that show up in claims, not just on a map

Workers' compensation, licensure, and hospital infrastructure all run on separate tracks in each state, even though the line between them is only a border.

ND North Dakota

  • Workers' compensation: Every workplace injury claim goes to Workforce Safety & Insurance, the state's own monopolistic fund. Private insurers cannot write workers' compensation policies in North Dakota, so there is one claims process and one fee schedule to learn, not several.
  • Licensure: North Dakota participates in the Interstate Medical Licensure Compact, so a physician already licensed in another compact state can add North Dakota faster than a standard state-by-state application. Payer credentialing still starts from zero once the license clears.
  • Hospital and clinic mix: 36 Critical Access Hospitals, one Rural Emergency Hospital, and two Indian Health Service units carry a large share of rural coverage, out of 47 licensed general acute care hospitals statewide.
  • Frontier geography: Large parts of the state qualify as frontier counties, where population density is low enough that ambulance mileage and long-distance transport claims are routine rather than the exception.

SD South Dakota

  • Workers' compensation: Employers buy coverage from private insurance carriers regulated by the state's Division of Insurance, so which carrier applies (and which fee schedule and prior-authorization process comes with it) depends on the employer, not one statewide fund.
  • Licensure: South Dakota was also among the earlier states to join the Interstate Medical Licensure Compact, which speeds up cross-border licensure for the specialists and locum physicians who cover both states.
  • Hospital and clinic mix: 39 Critical Access Hospitals, 56 Rural Health Clinics, and 39 Federally Qualified Health Center sites make up a denser network of rural access points than North Dakota's.
  • Tribal health system: Four Indian Health Service hospitals serve patients across South Dakota's nine reservations, a larger tribal health footprint than its northern neighbor's.

Shared What stays the same on both sides

Medicare claims from both states still route through the same contractor, and providers on both sides draw from the same small pool of certified coders and credentialing specialists. But a claims process built around one state's workers' compensation fund, licensure timeline, or hospital mix will not hold up if it gets applied to the other state without adjustment.

Where practices get tripped up

Problems that come from the systems themselves, not from paperwork

Each challenge below traces back to a real difference in how the two states regulate coverage, licensure, or facility types, not a generic revenue-cycle complaint.

1Two workers' comp systems, one shared workforce

Agricultural and energy-sector employers often run crews that cross the state line, so a clinic near the border can see a work injury billed to Workforce Safety & Insurance one day and to a private carrier the next, with no overlap between the two processes.

2Swing beds change the billing rules mid-stay

Critical Access Hospitals in both states routinely convert acute beds into swing beds for post-acute care, and that stay bills under the hospital's own cost-based rate instead of the standard skilled nursing facility payment system, a switch that's easy to miss.

3A cleared license doesn't mean a clean payer panel

The Interstate Medical Licensure Compact gets a physician licensed to practice in the other state quickly, but Medicaid enrollment, commercial contracts, and CAQH profiles for that state still have to be built from scratch before claims can go out.

4Frontier geography shows up as mileage disputes

When the nearest specialist or hospital is an hour or more away, ambulance and long-distance transport claims carry mileage totals well above what a reviewer in a denser state expects, which gets those claims flagged for extra documentation.

5Tribal health billing isn't sized the same on both sides

South Dakota's tribal and Indian Health Service network, spread across nine reservations, is considerably larger than North Dakota's, so a billing team built around one state's tribal claim volume ends up under-resourced for the other.

6Small facilities run billing without a dedicated coder

Many of the smallest Critical Access Hospitals and Rural Health Clinics in both states rely on registration or front-office staff to double as billing contacts, so questions about a claim often route through whoever happens to be covering the desk.

What we handle

Billing built for two separate systems, not one combined region

Every service below accounts for the fact that a claim in North Dakota and the same claim in South Dakota can run through entirely different payers and rules.

๐Ÿงพ

Medical Billing

Claims built around whichever system actually applies: Workforce Safety & Insurance for a North Dakota work injury, a private carrier for a South Dakota one, or a state Medicaid program for either, since treating them the same causes avoidable denials.

๐Ÿ”ค

Medical Coding

Certified coders apply current ICD-10, CPT, and HCPCS codes with attention to the swing bed transition, Critical Access Hospital billing methods, and the ambulance mileage coding this region's geography requires.

๐Ÿชช

Credentialing

Payer enrollment and CAQH maintenance are handled separately for each state's Medicaid program and commercial payers, because an Interstate Medical Licensure Compact license clears the medical board, not the payer panel.

๐Ÿ”„

Revenue Cycle Management

End-to-end RCM, from registration through reporting, built around two different workers' comp systems, two state Medicaid programs, and a hospital mix that includes swing beds and tribal facilities.

โœ…

Eligibility Verification

Coverage confirmed before the visit, including which workers' comp fund or private carrier applies to a work-related injury, so the wrong payer never gets billed first.

๐Ÿ“‹

Prior Authorization

Tracked separately by payer, since an authorization from Workforce Safety & Insurance carries no weight with a private workers' compensation carrier or a state Medicaid program.

๐Ÿšซ

Denial Management

Root-cause correction tied to the specific payer that denied the claim, whether that's a state fund's own review process, a private carrier's utilization review, or a Medicaid program's code.

๐Ÿ’ณ

Payment Posting

Accurate reconciliation of cost-based Critical Access Hospital and swing bed payments alongside standard fee-for-service postings, so nothing gets flattened into one generic rate.

๐Ÿ“ž

A/R Follow-Up

Persistent follow-up on aging claims, with extra attention paid to facilities that don't have dedicated billing staff on-site to answer payer questions directly.

Specialties we bill for

Coverage for the specialties this region actually has

Occupational & Orthopedic Medicine

Agricultural and energy-sector injuries drive steady claim volume, and whether a claim goes to Workforce Safety & Insurance or a private carrier depends entirely on which state and employer are involved.

Emergency Medicine & EMS

Long transport distances across frontier counties make ambulance mileage documentation a routine part of claims on both sides of the border, not an edge case.

Family & Rural Primary Care

Billing built around the Rural Health Clinic and Federally Qualified Health Center models that carry a large share of primary care access in both states.

Psychiatry & Behavioral Health

Telehealth-heavy delivery that depends on providers holding active licenses in both states, often through the Interstate Medical Licensure Compact, before a single visit can be billed correctly.

General Surgery

Coding attentive to how Critical Access Hospitals bill surgical procedures differently from a standard acute-care hospital.

Home Health & Hospice

Long travel routes between visits and separate state oversight of home health agencies in each state shape how these claims get built and followed up.

Skilled Nursing & Swing Bed Care

Post-acute stays billed correctly whether they happen at a standalone skilled nursing facility or inside a Critical Access Hospital's swing bed program.

Multi-Facility & Multi-State Groups

Registration accuracy, charge capture, and payment posting kept consistent across departments and NPIs for systems operating on both sides of the state line.

Our process

How a claim moves through our revenue cycle

1

Patient Registration

Employer and injury details captured at intake so a work-related visit is flagged for Workforce Safety & Insurance or a private carrier immediately, not discovered after the claim is built.

2

Coverage Verification

Active coverage confirmed against the correct payer, including which workers' comp system applies, before the appointment happens.

3

Coding Review

ICD-10, CPT, and HCPCS codes checked against Critical Access Hospital, swing bed, and payer-specific rate rules.

4

Charge Entry

Modifiers applied exactly as each payer requires, including the codes tied to ambulance mileage and long-distance transport.

5

Claim Submission

Clean claims formatted to each payer's specific requirements, whether that payer is a state fund, a private carrier, or a Medicaid program.

6

Payment Posting

Payments reconciled line by line, including cost-based and swing bed rates that don't match a standard fee schedule.

7

Denial Management

Denials triaged by the specific payer and reason code, then corrected at the source instead of resubmitted as-is.

8

Appeals

Filed within each payer's own appeal window, since a state fund's timeline and a private carrier's timeline are rarely the same.

9

A/R Follow-Up

Aging claims worked on a consistent schedule, with extra attention paid to facilities that don't have billing staff on-site.

10

Reporting

Clear reporting on collections, denial trends, and A/R days broken out by payer, not blended into one number.

Why outsource

Why practices in both states choose to outsource

Both states draw billing and coding talent from the same small labor pool, and the systems themselves are different enough that in-house staff rarely have time to master both.

๐Ÿชช

Credentialing takes longer than licensure

An Interstate Medical Licensure Compact license can clear in weeks, but building out Medicaid enrollment, commercial contracts, and CAQH profiles in a second state is a separate, slower project that in-house staff often can't run alongside daily billing.

๐Ÿ”„

Two systems rarely fit one job description

A biller who knows Workforce Safety & Insurance inside and out didn't necessarily learn the private workers' comp market on the other side of the border, and very few in-house hires are asked to master both.

๐Ÿฅ

Small facilities can't carry a specialist for every system

A Critical Access Hospital or Rural Health Clinic with one biller can't reasonably track swing bed rules, two different workers' comp systems, and Medicaid at the same depth a dedicated team can.

FAQ

Common questions about billing across both states

Does workers' compensation billing work the same way in North Dakota and South Dakota?

No. North Dakota requires every workplace injury claim to go through Workforce Safety & Insurance, the state's own no-fault fund, since private insurers aren't permitted to write workers' comp policies there. South Dakota employers buy coverage from private carriers, so the claim routes to whichever insurer that employer carries.

If a physician is licensed through the Interstate Medical Licensure Compact, are they ready to bill in the other state?

Not yet. The compact speeds up the medical license itself, but Medicaid enrollment, commercial payer contracts, and CAQH maintenance in the new state still have to be built separately before a claim can be submitted.

Do you bill for swing bed stays at Critical Access Hospitals?

Yes. A swing bed stay bills under the hospital's own cost-based rate rather than the standard skilled nursing facility payment system, and our coders track that switch as it happens rather than after the fact.

How many Critical Access Hospitals are you set up to support across the two states?

North Dakota currently has 36 Critical Access Hospitals and one Rural Emergency Hospital, while South Dakota has 39 Critical Access Hospitals alongside a much larger network of Rural Health Clinics and Federally Qualified Health Centers. We staff for both facility mixes rather than assuming one looks like the other.

Can one billing team really handle both states given how different the systems are?

Yes, this is one of the more common setups we support. We keep separate processes for each state's workers' comp system, licensure and credentialing timeline, and hospital mix, while still giving the practice one unified view of collections and denials.

Do you handle ambulance and long-distance transport billing?

Yes. Frontier-county geography in both states means mileage totals on ambulance claims run higher than what a reviewer in a denser state expects, so documentation for those miles gets extra attention before the claim goes out.

What happens when a provider treats patients in both states?

We credential and bill that provider separately in each state, since a North Dakota Medicaid panel and a South Dakota Medicaid panel are two different enrollments, while keeping reporting for the practice unified across both.

We're a small rural clinic without a dedicated coder on staff. Can you still help?

Yes. This is a common situation for Rural Health Clinics and small Critical Access Hospitals in this region, and it's one of the main reasons practices bring in outside billing support in the first place.
