Medical Billing Services in Louisiana
Louisiana runs Medicaid through Healthy Louisiana — nearly all members sit in MCOs led by Louisiana Healthcare Connections, AmeriHealth Caritas and Healthy Blue — with a 12-month state filing window backstopping shorter plan deadlines. The 2016 expansion made Louisiana an early Deep South adopter, so Medicaid mix here runs heavier than in its non-expansion neighbors, and Ochsner Health's statewide sprawl shapes referral flows like few single systems anywhere. Commercially, Blue Cross Blue Shield of Louisiana remains the independent, dominant Blue. Billing here rewards MCO fluency — the state rulebook matters less than the five plan manuals that govern almost everyone.
Healthy Louisiana: filing rules that decide whether you get paid
Administered by the Louisiana Department of Health (LDH)
Healthy Louisiana claims carry a 12-month state window from the date of service, but nearly all members are in managed care — Louisiana Healthcare Connections (Centene), AmeriHealth Caritas Louisiana, Healthy Blue (BCBSLA/Elevance), UnitedHealthcare Community Plan, Humana Healthy Horizons and Aetna Better Health — so each plan's manual sets the working deadlines, auth lists and appeal routes. The 2016 expansion pushed coverage deep into the working-age adult population, making eligibility churn at redetermination a bigger denial source here than in non-expansion neighbors. Provider enrollment runs through LDH's Medicaid provider enrollment portal.
Deadlines for every major payer — including Louisiana Medicaid — live in our timely filing limits tool, with an interactive deadline checker.

Louisiana billing rules that move real money
Plan manuals over state rules
With nearly all Healthy Louisiana members in MCOs, the practical billing law is five-plus plan manuals — filing windows, auth lists and appeal clocks vary by plan, and the state's 12-month window is a backstop you should never need. We work each plan to its own manual and calendar its own deadlines.
Redetermination churn
Louisiana's large expansion population cycles through eligibility redeterminations, and coverage that lapses mid-treatment is a leading denial source. Visit-level eligibility verification — and rechecking before high-cost services — prevents claims built against coverage that ended the month before.

Credentialing & enrollment in Louisiana
Physician licensing in Louisiana runs through the Louisiana State Board of Medical Examiners, and payer enrollment is its own workstream on top of it — state Medicaid enrollment, CAQH upkeep, and individual plan contracting each on their own timeline. Our credentialing service manages the full stack for Louisiana providers, and our credentialing calculator estimates realistic timelines by payer.
Louisiana billing FAQs
What is the timely filing limit for Louisiana Medicaid?
12 months from the date of service at the state level — but nearly all members are in Healthy Louisiana MCOs whose manuals set shorter working limits. We bill to the plan deadline, not the backstop.
Which Healthy Louisiana plans do you bill?
All the major MCOs — Louisiana Healthcare Connections, AmeriHealth Caritas, Healthy Blue, UnitedHealthcare Community Plan, Humana Healthy Horizons and Aetna Better Health — each to its own manual, auth lists and appeal routes.
Why do my Medicaid patients keep losing coverage?
Redetermination churn — Louisiana's large expansion population cycles through eligibility reviews, and lapses mid-treatment are common. We verify at the visit level and recheck before high-cost services so claims aren't built on expired coverage.
Do you work with Ochsner-affiliated practices?
Yes — Ochsner's statewide footprint shapes referral flows and payer contracting across Louisiana, and we bill for independent and affiliated practices alike, including claims involving Ochsner Health Plan's MA products.
