What Are Medical Billing Companies in Mississippi?
Medical billing companies in Mississippi manage claims, denials, payment follow-up, patient balances, and related revenue cycle work for medical practices. Under the Mississippi Prior Authorization Reform Act, a service is automatically deemed authorized when an insurer misses the deadlines the article sets, and Miss. Code Ann. section 83-9-5 requires a clean electronic claim to be paid within 25 days or carry 1.5 percent monthly interest.
Mississippi Practices Are Losing Revenue in Places They Cannot See
Aged AR is obvious. An authorization a payer walked back three months after the visit is harder to see and costs the same. Mississippi wrote an unusually blunt answer to that problem in 2024, and most practices here still bill as though it never passed.
The Mississippi Prior Authorization Reform Act took effect on 1 July 2024. Section 83-5-931 is one sentence long and it is the whole point: when an issuer misses a deadline or any other requirement in the article, the services under review are automatically deemed authorized. Section 83-5-923 then bars the carrier from revoking, limiting, conditioning or restricting an approval while it stays valid, and section 83-5-925 holds it valid for six months or the length of treatment, whichever is shorter.
Collecting on that requires one thing almost nobody keeps: a date-stamped record of when the request went out, when the payer answered, and exactly what it asked for. Most practices have a fax confirmation and a note in the chart. When the denial lands seven weeks later, nobody can prove the clock ran out, so the adjustment posts and the file closes.
The prompt pay statute repeats the pattern. A clean electronic claim is due in 25 days and a paper claim in 35, with 1.5% per month running from the day after payment was due. But a claim submitted more than 30 days after the date of service is not a clean claim under that same section, so a slow billing cycle quietly forfeits the interest before anyone thinks to ask for it.
Medical Billing Services for Mississippi Practices
Full-Service Medical Billing
Our full-service medical billing team manages the revenue cycle from eligibility through payment posting and zero balance. Your dedicated team works inside your existing practice management or EHR system instead of forcing you through a disruptive software migration.
Medical Coding
Our certified medical coders review documentation and apply the appropriate coding workflows for your specialty and payer mix. Better coding upstream can prevent avoidable denials downstream.
Denials and AR Recovery
Old accounts are often the fastest place to find recoverable revenue. Our denials and AR recovery service prioritizes aged accounts, identifies denial patterns, works payer responses, and pursues appropriate appeals and follow-up until the account reaches resolution. In Mississippi that includes checking whether a late payment carried the 1.5% monthly interest section 83-9-5 requires.
Eligibility and Benefits Verification
Eligibility problems can create avoidable write-offs and patient-balance confusion. We verify coverage and benefits so your team has the information needed before claims and patient statements move forward. In a state that did not expand Medicaid, telling coverage from self-pay before the visit is most of the work.
Prior Authorization
Authorization requirements vary by payer, plan, service, and specialty. Mississippi sets a 7-day nonurgent clock, 48 hours for urgent requests, and 2 business days for pharmacy, and deems the service authorized when an issuer misses them, so we manage prior authorization workflows against those clocks rather than waiting on the payer.
Patient Billing
Patient balances are part of the revenue cycle too. Our patient billing support keeps statements, balances, and follow-up organized so your practice is not leaving the final portion of earned revenue unattended.
Credentialing
Credentialing problems can delay payments before the first claim is ever submitted. We support provider enrollment and credentialing so practices stay operational with the plans they serve, including the Division of Medicaid file that has to be current before a practice can contract with Magnolia Health, Molina or TrueCare.
RCM, CCM and Telehealth
Practices increasingly need billing workflows that account for multiple care models and remote services. We support revenue-cycle processes for RCM, chronic care management, and telehealth programs, including the Mississippi remote patient monitoring rules, with medical virtual assistant support where a practice needs front-office coverage alongside billing.
Dashboards and Automations
You should not need to wait for a monthly spreadsheet to understand what is happening to your revenue. We use reporting and workflow automation to make trends in AR, denials, collections, and billing performance easier to identify and act on.
How Our Medical Billing Process Works
1. Start With a Billing Review
We begin with a 30-minute review of your AR aging, denial patterns, payer mix, and current billing workflow. The goal is simple: identify what is actually costing you money and where we would start.
2. Build the Revenue Recovery Plan
We identify the accounts, payer issues, coding patterns, workflow gaps, and filing risks that deserve attention first. You get a clear view of what should be worked immediately and what needs a process change.
3. Start With the Oldest Money
Working aged AR comes first because it represents revenue you have already earned. Our team works the backlog while establishing a consistent process for new claims and daily billing.
4. Run the Full Cycle
Once the foundation is in place, we take over the agreed portion of the revenue cycle: eligibility, coding, submissions, payment posting, denials, appeals, AR follow-up, patient billing, and reporting.
5. Improve the System, Not Just the Claims
The goal is not to create a permanent cycle of denials and appeals. We look for repeatable patterns so the practice can prevent the same billing problems from occurring again.

Medical Billing in Mississippi: Understanding the Payer Landscape
Mississippi runs on an independent Blue. Blue Cross & Blue Shield of Mississippi is a licensee headquartered in Flowood rather than a subsidiary of a multistate holding company, which means medical policy, appeal routing, and provider relations are decided in state. Escalation paths that work on an Elevance or Anthem plan in another state have no equivalent here.
Medicare is the second concentration, and its shape matters more than its size. 640,993 Mississippians were enrolled as of September 2024, more than 17% of the state. Only 43% sit in Medicare Advantage against roughly 50% nationally, so traditional Medicare still carries more of the book here than in most states. Nearly 16% of the state’s beneficiaries qualified through disability rather than age, against about 11% nationally, which is why dual eligibility, secondary billing, and QMB balance-billing rules come up far more often on a Mississippi remittance than the enrollment total suggests. Original Part A and Part B claims go to Novitas Solutions, the Jurisdiction H contractor for Arkansas, Colorado, Louisiana, Mississippi, New Mexico, Oklahoma and Texas.
Medicaid is smaller than the state’s health profile would predict, because Mississippi never expanded. 590,816 people were covered as of October 2025, and roughly 74,000 adults sit in the coverage gap with no Medicaid category and no marketplace subsidy. Those patients arrive as self-pay in a state where self-pay usually means uncompensated, which puts almost all of the recoverable money on the payer side of the ledger.
Managed care runs through three coordinated care organizations: Magnolia Health, Molina Healthcare, and TrueCare. That roster is new. TrueCare began serving MSCAN and CHIP members on 1 July 2025 after the state re-awarded contracts, and UnitedHealthcare came off the panel. A provider has to be credentialed through the Division of Medicaid before contracting with any CCO, so a practice that let its DOM file go stale is not merely out of network with TrueCare, it cannot start the contracting step at all.
Workers’ compensation has a published grid, which not every state offers. The Mississippi Workers’ Compensation Medical Fee Schedule prices professional services off Medicare relative value units effective 1 January 2025 and fills gaps with FAIR Health data. It also carries penalties in both directions, interest and percentage penalties for late billing as well as late payment, so a work injury claim that sits in a hold bucket for a month is a penalty risk, not just a delay.
Facility mix matters here more than in most states. Mississippi has 30 critical access hospitals and 7 rural emergency hospitals, with 1,488,155 residents, 50.5% of the state, living outside a metro area. A rural emergency hospital bills under a different Medicare payment model than it did as a critical access hospital, and the physician claims attached to it do not change at all. Getting one right and the other wrong is a common and expensive split.
Mississippi Billing Rules That Can Affect Your Revenue
12 months from date of service
Timely filing
25 days electronic, 35 days paper
Prompt-pay requirement
Mississippi Medicaid (MSCAN)
State Medicaid program
Mississippi’s prompt pay rule sits inside Miss. Code Ann. 83-9-5. A clean claim filed electronically is payable within 25 days of receipt of due written proof. On paper it is 35 days. If the claim is not denied for valid and proper reasons by the end of that window, interest accrues at 1.5% per month from the day after payment was due.
The definition of a clean claim decides who ends up with that interest. Four categories fall outside it: a duplicate filed within 30 days of the original, a claim submitted fraudulently or on material misrepresentation, a claim requiring information on a preexisting condition, coordination of benefits or subrogation, and a claim submitted more than 30 days after the date of service. That last exclusion is the one that gets ignored. A practice billing on a two-week cycle keeps its interest rights. A practice that batches at month end forfeits them on part of its book, permanently, and no remittance will ever say so.
Prior authorization runs on the Mississippi Prior Authorization Reform Act, effective 1 July 2024, and the deadlines are short. A nonurgent determination is due no later than 7 calendar days. An urgent determination is due within 48 hours of the issuer receiving all information needed to complete the review. Pharmaceutical requests run on the tighter clock in section 83-9-6.3, 2 business days. Miss any of it and section 83-5-931 deems the service authorized.
Four more provisions in the same article are worth building workflow around. An approval stays valid for the lesser of six months, the length of treatment set by the treating professional, or the renewal of the plan, and a dosage change does not restart it. A carrier may not revoke or narrow a valid approval, though it keeps the right to run post-service payment integrity review. A new issuer must honor an approval granted by the prior carrier for at least the first 90 days when the documentation is handed over. And an issuer must give contracted providers at least 60 days of written notice before a new or amended prior authorization requirement takes effect, with a short list of exceptions it has to report to the department.
Medicaid keeps its own calendar. A claim must be filed within 12 months of the through date of service. Corrected claims run to two years from the initial date of service. Medicare crossover claims for coinsurance and deductible must reach the Division of Medicaid within 180 days, which is the deadline most often missed, because staff assume the crossover is automatic and never reconcile the ones that did not land. For a newly enrolled provider the 12 months run from the date of the provider eligibility letter rather than the date of service, which is the difference between billing a backlog and writing it off.
Telehealth reimbursement is narrower than the marketing suggests, and oddly specific where it does exist. Mississippi does not mandate explicit payment parity for live video, but under Miss. Code Ann. 83-9-353 store-and-forward and remote patient monitoring must be covered to the same extent as an in-person consultation, with a floor of $10.00 per day each month for remote monitoring and $16.00 per day where medication adherence management is included, for patients diagnosed within the prior 18 months with a listed chronic condition. Medicaid does not pay audio-only outside a declared emergency. The private payer telemedicine sections are also written with a sunset and stand repealed after 1 July 2028, so a program built on them needs a date in the calendar.
Mississippi Medical Practices We Serve
We bill for cardiology, oncology, nephrology, endocrinology, and geriatrics, where authorization volume is highest and the Prior Authorization Reform Act does the most work. Every request goes out with a timestamp and a record of what was asked for, because a determination past 7 calendar days, or 48 hours on an urgent case, is a deemed authorization rather than a pending one.
We bill for orthopedics, physical therapy, chiropractic, pain management, and occupational medicine, where work injuries are a standing part of the book. Mississippi publishes a fee schedule built on Medicare RVUs, so an underpayment is provable line by line, and the same schedule penalizes late billing on the provider side, which makes a stalled work injury queue an active liability.
We bill for primary care, internal medicine, pediatrics, and OB/GYN, including rural health clinics and FQHC sites. In a state that did not expand Medicaid, with 9.7% uninsured against 8.2% nationally, the sorting work at the front end decides the month: coverage confirmed before the visit, self-pay identified as self-pay, and nothing billed to a plan that will silently sit on it.
We bill for behavioral health, psychiatry, therapy, clinical social work, and substance use disorder treatment. That means MSCAN work across Magnolia Health, Molina and TrueCare, three separate authorization workflows, plus the audio-only limits in the Mississippi Medicaid telehealth rules that do not match the commercial ones.
We bill for emergency medicine, anesthesiology, radiology, pathology, and hospitalist groups, where claim volume is high and the contact with the patient is brief. With 43% Medicare Advantage penetration and nearly 16% of the state’s Medicare population qualifying through disability, the secondary claim is part of the daily run rather than an exception queue.

Meridian
Mississippi’s two busiest corners both sit on a state line, and they do not behave the same way. A DeSoto County practice in Southaven or Olive Branch works the Memphis market, which means Tennessee patients, Tennessee plan contracts, and a Medicare split: the Mississippi site files Part A and Part B to Novitas in Jurisdiction H while a Memphis location files to Palmetto GBA in Jurisdiction J, with separate enrollment and separate PTANs for the same physicians. On the Gulf Coast the line runs the other way. A Gulfport or Biloxi group with a site across in Louisiana stays with the same Medicare contractor, because Jurisdiction H covers both states, but picks up an entirely different Medicaid program and fee schedule. One border changes the contractor and not the state rules; the other changes the state rules and not the contractor.
We run the same model in other states, with the payer rules, filing windows and Medicaid structure rebuilt for each one.

What Mississippi Practices Say About Working With Luxen
“Our clinicians see patients in private homes, assisted-living communities, and the clinic, but the correct care setting did not always reach the claim. Luxen standardized our place-of-service workflow, reduced related denials from 19% to 4%, and recovered $36,700 from affected accounts.”
Operations Director, Home-Based Primary Care Practice, Jackson, Mississippi
“When a screening mammogram led to diagnostic imaging, the related services were handled through separate billing workflows. Luxen connected the full episode, reduced screening-to-diagnostic claim denials by 67%, and shortened average submission time from seven days to two.”
Practice Administrator, Women’s Imaging Center, Gulfport, Mississippi

What Does Medical Billing Cost in Mississippi?
3% to 6% of collections
Luxen’s pricing generally falls between 3% and 6% of collections, depending on claim volume, specialty, payer mix, and how much of the revenue cycle your practice hands over.
Larger-volume practices can generally access the lower end of the range because billing economics improve as claim volume increases. A smaller or more complex practice may fall toward the higher end because the amount of work per account is greater.
For comparison, published billing-industry pricing guides commonly place percentage-based medical billing somewhere around the mid-single digits, with higher ranges for smaller or more complex practices.
The more important question, however, is not whether a billing company charges 3%, 4%, 5%, or 6%.
It is what happens to collections after you hire them.
A lower fee attached to weak billing is still expensive.
The Risks of Outsourcing Your Medical Billing
Outsourcing is not automatically the right choice for every practice.
A billing company is a poor fit if you are unwilling to share operational visibility, if the vendor uses a rotating pool of people who do not learn your practice, or if the company cannot explain why your claims are being denied.
There is also a real risk in choosing a vendor that promises aggressive collection improvements without understanding your payer mix and specialty.
That is why Luxen starts with the numbers.
You should see the AR aging. You should understand your major denial categories. You should know what is being worked. And you should know what your billing company believes is realistically recoverable.
The right outsourcing relationship should make your revenue cycle more visible, not less.
How Much Revenue Are You Missing?
Look at your AR aging.
- How much is sitting past 90 days?
- How much is past 120 days?
- Which payers represent the largest outstanding balances?
- What are your top five denial reasons?
- How many claims are repeatedly resubmitted without a clear resolution?
- How much patient responsibility remains uncollected?
- How many claims are approaching a filing deadline?
Those numbers tell a story.

A Message From the Luxen Founder
I started Luxen because medical practices should not have to choose between doing great clinical work and running a financially healthy business.
Billing is too important to be treated as an afterthought. When claims are submitted incorrectly, denials sit untouched, or aged AR is ignored, the practice feels it everywhere, from cash flow and payroll to staffing decisions and growth.
Our job is to bring discipline to that part of the business.
We work inside the systems practices already use, build accountable billing workflows, and focus on the revenue that is actually recoverable.
We believe your billing partner should know your numbers, your specialty, your payers, and your practice, not just your account number.
Founder, Luxen Talent

Mississippi Medical Billing FAQs
Why outsource medical billing in Mississippi?
Mississippi rules only pay out if someone is keeping dates. The Prior Authorization Reform Act deems a service authorized when the issuer misses its deadline, 7 calendar days for a nonurgent request and 48 hours for an urgent one. A valid approval cannot be revoked, holds for six months, and a new carrier must honor it for 90 days. Section 83-9-5 adds 1.5 percent monthly interest on a clean claim not paid within 25 days electronically, but only if the claim went out within 30 days of the date of service. None of that converts into money without a claim-level record of when each request and each claim was sent.
Do you work with Mississippi Medicaid and MSCAN?
Yes. We work with all three coordinated care organizations, Magnolia Health, Molina Healthcare and TrueCare, plus fee-for-service Mississippi Medicaid and CHIP. TrueCare replaced UnitedHealthcare on the panel on 1 July 2025, and a provider has to be credentialed through the Division of Medicaid before contracting with any CCO, so we keep the DOM file current first. Claims must be filed within 12 months of the through date of service, corrected claims run to two years, and Medicare crossover claims for coinsurance and deductible must reach the Division within 180 days.
How do you handle denied claims?
We work denials through resolution and track the pattern behind them, because the same denial code can mean different things across payers. In Mississippi that includes checking the authorization timeline on every denial tied to medical necessity, since a determination made after the statutory deadline is a deemed authorization, and checking whether a late payment carried the 1.5 percent monthly interest it owed. It also means challenging any takeback against an approval that was still valid, because a carrier may not revoke or narrow one it has already issued.
Is this cost-effective for a small Mississippi practice?
Luxen’s pricing generally falls between 3% and 6% of collections, depending on volume, specialty, payer mix, and scope. Mississippi did not expand Medicaid and runs a 9.7% uninsured rate against 8.2% nationally, so patient-side collection has a hard ceiling and the recoverable money sits with payers. Authorizations that were deemed approved and denied anyway, prompt-pay interest never invoiced, work injury claims paid under a published fee schedule nobody checked against, and crossover claims that missed the 180-day Medicaid window are all revenue the practice already earned.
