Chiropractic insurance billing in New Orleans, LA.

Blue Cross and Blue Shield of Louisiana (Louisiana Blue) is the dominant commercial and ACA-marketplace carrier across Orleans and Jefferson parishes, with UnitedHealthcare a distant second; together the state’s two largest insurers control roughly 80% of the market.

A large share of New Orleans patients also sit in Louisiana Medicaid managed-care, and Medicare Advantage now covers a majority of local Medicare beneficiaries, with about 55% of eligible Medicare members nationally in MA plans and 117 MA plans available statewide in 2026 — so a biller here routinely works Louisiana Blue, Medicaid MCO, and MA prior-auth and claims rules side by side.

The entire state, including the New Orleans-Metairie metro, falls in a single statewide Medicare Physician Fee Schedule locality — Locality 99, ‘Rest of Louisiana’ — administered by Novitas Solutions, the Part B MAC for Jurisdiction JH.

There is no separate New Orleans locality, so a Crescent City practice is paid on the same GPCIs as rural Louisiana. Those GPCIs run below the 1.000 national average (notably a practice-expense GPCI around 0.885 for 2026), making Louisiana a relatively LOW-cost, lower-reimbursement area.

Workers’ comp here is shaped by the maritime and industrial economy along the Mississippi — the Port of New Orleans (Port NOLA) and the river’s petrochemical/refinery corridor — so a large slice of on-the-job injuries fall under the federal Longshore and Harbor Workers’ Compensation Act (LHWCA) rather than state comp, alongside heavy-lifting, crush, and chemical-exposure claims.

State workers’ comp is billed against the Louisiana Office of Workers’ Compensation Administration (OWCA) reimbursement schedule, with carriers/employers given 60 days to pay or formally dispute a bill; LHWCA claims are paid through DOL/OWCP, meaning a New Orleans biller must correctly route maritime cases to the federal track to get paid.

Orleans Parish is a tort/at-fault state venue — Louisiana has no PIP/no-fault, so auto-injury bills are recovered from the at-fault driver’s liability carrier or the patient’s own MedPay/uninsured-motorist coverage, typically through a third-party settlement rather than direct first-party PIP payment.

Providers can secure payment with a statutory medical lien (‘privilege’) under La. R.S. 9:4752–9:4753, but attorney’s fees are paid first out of the settlement and valid liens next, so practices often wait on case resolution. Louisiana’s modified-comparative-fault rule (effective Jan. 1, 2026) bars recovery for plaintiffs 51%+ at fault, adding collection risk on contested crashes.

The metro is anchored by Ochsner Health — the Gulf South’s largest nonprofit system, with hospitals across Jefferson, Orleans, St. Bernard, St. Charles, and St. Tammany — and LCMC Health, whose New Orleans facilities include University Medical Center New Orleans (the region’s Level 1 Trauma Center and the natural funnel for severe auto-injury/PI patients), Touro, Children’s Hospital, and the former Tulane and East/West Jefferson hospitals.

These two systems dominate PI referral patterns and payer-contract leverage in the market.
