Medical billing services · North Carolina & South Carolina

North Carolina expanded Medicaid. South Carolina held the line.

Two states, one shared border, and two Medicaid programs that no longer resemble each other. North Carolina rolled expansion into a five-plan managed care system in December 2023. South Carolina kept its program fee-for-service and capped who qualifies. A billing team built for one state usually mishandles claims filed in the other.

North Carolina Medicaid

Expanded · Managed Care Statewide

  • Expansion took effect December 1, 2023, and passed 600,000 enrollees within its first year
  • Five Standard Plans carry most members: AmeriHealth Caritas, Healthy Blue, UnitedHealthcare Community Plan, WellCare and Carolina Complete Health
  • Four regional Tailored Plans, Alliance Health, Partners Health Management, Trillium Health Resources and Vaya Health, took over behavioral health, I/DD and TBI claims on July 1, 2024
  • The EBCI Tribal Option and NC Medicaid Direct still run fee-for-service for anyone outside managed care

South Carolina Medicaid

Not Expanded · Managed Care Plus FFS

  • South Carolina has not adopted Medicaid expansion, so many low-income working adults remain without a coverage path
  • Five MCOs cover most members: Absolute Total Care, Healthy Blue, Humana Healthy Horizons, Molina Healthcare and Select Health (First Choice)
  • Healthy Connections Prime, the state's dual-eligible demonstration, ended January 1, 2026; those members are moving into a standard MCO or a D-SNP
  • That same date, adults 18 and older and nursing facility residents were carved into MCO coverage for medical services, while waiver services stayed fee-for-service

The payer mix

The rules change before the map does

A claim crossing the state line doesn't get gentler treatment. Here's what actually decides how each one gets paid.

Medicare

NC + SC

Palmetto GBA processes Part A and Part B claims for both states under Jurisdiction M. Coverage determinations, appeal windows and the eServices portal are identical whether the visit happened in Asheville or Aiken.

What changes is which Medicare Advantage plan sits on top of it.

Medicare Advantage

NC + SC

Medicare Advantage enrollment is common throughout both states, and plan mix differs county by county. Humana, UnitedHealthcare and Blue Cross plans dominate different pockets of each state, each with its own prior authorization list and its own timely filing clock.

Practices need payer-specific workflows that account for these differences before claims are submitted.

NC Medicaid

NC

Five Standard Plans, four regional Tailored Plans for behavioral health and I/DD, the EBCI Tribal Option, and NC Medicaid Direct for anyone not yet assigned to a plan.

Five different payer IDs and five different clean-claim windows, sitting under one beneficiary.

SC Medicaid

SC

Healthy Connections Medicaid still runs largely fee-for-service outside its five contracted MCOs, and the January 2026 carve-in moved a new slice of adult and nursing-facility claims into managed care.

Two systems, two sets of authorization rules, one program name.

TRICARE and VA

NC + SC

Fort Liberty, Fort Jackson, Marine Corps Air Station Beaufort and Shaw Air Force Base put a large TRICARE population within reach of Carolinas practices.

TRICARE East claims route through Humana Military, on a timely filing clock that runs separately from Medicare or Medicaid.

Multi-location practices

NC + SC

Groups with a clinic in Charlotte and one in Rock Hill, or in Wilmington and Myrtle Beach, are running two Medicaid programs, two fee schedules and two provider enrollment files under a single tax ID.

Nothing about that setup is automatic.

Revenue leakage

Where Carolinas practices actually lose revenue

Not generic denial trends. These are the specific failure points tied to current NC and SC rules.

SC

The Certificate of Need surge in South Carolina

Since South Carolina rolled back its Certificate of Need law in 2023, new imaging centers, surgery centers and specialty clinics have opened faster than payer enrollment can keep pace. A location that starts seeing patients before every payer ID is active bills at the wrong rate, or not at all.

NC

The Tailored Plan carve-out on the North Carolina side

Since July 2024, behavioral health, I/DD and TBI claims for roughly 210,000 North Carolinians route to one of four Tailored Plans instead of a Standard Plan. A claim filed to the wrong plan doesn't deny quickly. It sits.

SC

The dual-eligible reshuffle in South Carolina

Healthy Connections Prime closed on January 1, 2026, and its members are still being sorted into D-SNPs or standard MCOs. Until that settles at the plan level, claims for dual-eligible patients are an easy place for a payer mismatch to hide.

NCSC

Rural access gaps that don't match the map

North Carolina supports 20 Critical Access Hospitals and eleven small rural hospitals. Eight South Carolina counties have no hospital at all. Referral patterns cross county and sometimes state lines, and the documentation trail has to keep up with the patient, not the zip code.

NC

Standard Plan consolidation

Carolina Complete Health is folding into WellCare in North Carolina, which means provider contracts, payer IDs and fee schedules tied to the old plan need to be reverified before claims start bouncing.

How A2Z handles it

We staff for the payer mix you actually run

Support that treats NC and SC as two different jobs, not one job with a longer service area.

Dual-state eligibility checks

We verify benefits against the right plan type before the visit: Standard Plan, Tailored Plan, Healthy Connections MCO, or fee-for-service, on either side of the line.

Credentialing built for two enrollment systems

NCTracks and the Healthy Connections provider portal don't talk to each other. We track both applications, both revalidation clocks, and both effective dates so nothing lapses quietly.

Denial routing by plan, not by habit

A denial from Trillium Health Resources gets appealed differently than one from Molina. We match the appeal path to the actual plan on the claim.

Prior authorization tracked on two clocks

South Carolina's MCOs and North Carolina's Standard and Tailored Plans each set their own authorization windows. We track expiration dates separately so a stale authorization doesn't stall a claim.

Coding checked against state-specific edits

Local coverage determinations from Palmetto GBA apply the same way in both states. Medicaid-specific modifier and NDC rules do not. Coding gets checked against whichever set applies to that claim.

Reporting split by state and by plan

Your dashboard separates NC and SC receivables, denial rates and days in A/R by payer, so a slow month in one state doesn't get lost inside a good month in the other.

What we do

The same nine services, configured for two states

Service names don't change from state to state. What each one actually checks against does.

Medical Billing

Claims built against the correct plan and payer ID from the first submission, whether that's Palmetto GBA, a Standard Plan, or a Healthy Connections MCO.

Medical Coding

CPT, ICD-10 and HCPCS coding checked against Jurisdiction M's LCDs and each state's Medicaid-specific edits.

Credentialing

Enrollment tracked through NCTracks and the SC provider portal at the same time, with revalidation dates flagged before they're due.

Revenue Cycle Management

One workflow covering both states' claims, from registration through appeals, reported back to you by state.

Eligibility Verification

Checked against the specific plan type before the appointment, not just whether Medicaid is active.

Prior Authorization

Requested, tracked and renewed against each plan's own timeline, not a single default window.

Denial Management

Every denial routed to the appeal process that plan actually uses, inside its own filing deadline.

Payment Posting

ERA and EOB data posted daily so underpayments surface while they're still appealable.

A/R Follow-up

Aged claims worked by payer and by state, oldest and highest-dollar first.

Specialty focus

Specialty billing that accounts for both states

The same specialty can mean two different rule sets depending on which state the claim originated in.

Behavioral health and psychiatry

In North Carolina, this now means routing through one of four Tailored Plans instead of a Standard Plan. In South Carolina, it usually still means fee-for-service, with its own documentation rules for licensed independent practitioners.

Physical and occupational therapy

Visit caps and modifier requirements differ by plan type in both states. A therapy cap that resets under one Standard Plan doesn't necessarily reset the same way under a Tailored Plan or an MCO.

Orthopedics and pain management

High-volume CPT edits and multi-procedure payment reductions apply differently across Medicare, Medicare Advantage and each state's Medicaid plans, especially when billed alongside imaging.

Maternity and rural OB

Several Critical Access Hospitals in North Carolina have restarted labor and delivery after years without it, often staffed by family physicians rather than OB specialists, which changes how those claims get coded and reimbursed.

Urgent care

Charlotte, Greenville and the coastal corridor generate high claim volume across shifting Medicaid plan assignments, so registration accuracy at intake matters more here than almost anywhere else.

Home health and hospice

Palmetto GBA handles these claims separately from Part A and B claims, on their own edits and their own timely filing rules, in both states.

The claim lifecycle

Eleven steps. Skip one and the next ten inherit the mistake.

Most denials trace back to a step that happened well before the claim was even submitted.

  1. RegistrationDemographic and payer data captured against whichever of the five NC Standard Plans, four Tailored Plans, or five SC MCOs actually applies.
  2. Eligibility verificationConfirmed against the specific plan type, not just an active Medicaid status.
  3. Prior authorizationLogged against that plan's own authorization window and renewal date.
  4. Coding reviewChecked against Jurisdiction M's LCDs and whichever state Medicaid edits apply.
  5. Charge entryCharges matched to the plan-specific fee schedule before submission.
  6. Claim submissionFiled electronically through the correct clearinghouse and payer ID for that plan.
  7. Payment postingERA and EOB data posted daily so shortfalls surface immediately.
  8. Denial triageSorted by root cause and routed to the plan's own appeal process.
  9. AppealsFiled inside that plan's specific deadline, not a generic assumption.
  10. A/R follow-upAged claims worked oldest and highest-dollar first, by state and by payer.
  11. ReportingPerformance split by state, so results in one don't mask problems in the other.

Why outsource

Staffing this in-house is getting harder, not easier

Raleigh, Charlotte, Greenville and Columbia all have the same problem: large health systems hiring from the same small pool of experienced billers.

Hiring pressureAdvanced credentialing and coding certifications draw the same candidates that hospital systems in both states are also recruiting.
Turnover riskLosing one biller who understands both states' Medicaid programs can set a small practice back months, not weeks.
Compliance loadTwo Medicaid programs, two sets of managed care rules and one federal Medicare contractor mean twice the update calendar to track.
Continuous coverageClaims keep moving on both sides of the state line, even during a hire, a resignation or a leave of absence.

Frequently asked

Questions about billing in North Carolina and South Carolina

Is Medicare billing really identical in both states?

Yes, for Part A and Part B. Palmetto GBA runs Jurisdiction M for North Carolina, South Carolina, Virginia and West Virginia, so LCDs, the eServices portal and appeal deadlines are the same. What differs is which Medicare Advantage plan sits on top of that base coverage, and that varies by county.

What happened to South Carolina's Healthy Connections Prime program?

It closed on January 1, 2026. Members who were enrolled are moving to a Dual Eligible Special Needs Plan or a standard Healthy Connections MCO. Claims for affected patients need to be checked against their new plan assignment rather than the old Prime enrollment.

How does North Carolina's Tailored Plan system affect claims?

Since July 2024, behavioral health, I/DD and TBI claims for eligible members route to one of four regional Tailored Plans, Alliance Health, Partners Health Management, Trillium Health Resources or Vaya Health, instead of a Standard Plan. Filing to the wrong one is one of the more common new denial reasons we see.

Does South Carolina's Certificate of Need repeal change anything for billing?

It affects timing more than rules. Since the 2023 repeal, new facilities and service lines can open faster in South Carolina, which means payer enrollment and credentialing need to move at the same pace or claims start piling up unbilled.

Can one billing partner handle a practice with locations in both states?

That's most of what this page is about. We run NC and SC claims through the same workflow with separate reporting, so a location in Fort Mill and one in Charlotte don't get treated as a single, blended payer mix.

How long does credentialing take in North Carolina versus South Carolina?

Both typically run 60 to 120 days depending on the plan and how complete the application is at submission. NCTracks and the SC provider enrollment portal are separate systems with separate revalidation schedules, so we track them independently rather than assuming one timeline covers both.

Is telehealth billed the same way in both states?

The base Medicare telehealth rules are the same under Jurisdiction M. Medicaid telehealth policy is set separately by each state's program, and by each Standard Plan, Tailored Plan or MCO within it, so coverage and documentation requirements can differ by plan even inside the same state.
