Billing precision for Mississippi's cardiology practices
Mississippi carries one of the country's heaviest cardiovascular disease burdens, and Jackson is home to the Jackson Heart Study, the largest community-based study of heart disease in African Americans. That clinical volume means constant diagnostic testing, procedures, and chronic-care follow-up all of it dependent on documentation and coding being right the first time.
Four lanes, every claim
Mississippi has not expanded Medicaid under the ACA, so adult eligibility stays narrow. That shapes the panel: more Medicare and dual-eligible patients, more self-pay, and claims that route through four genuinely different systems.
Medicare Jurisdiction H
Novitas Solutions processes fee-for-service Medicare claims and publishes the Local Coverage Determinations that govern medical necessity for echocardiography, stress testing, and cardiac monitoring in this jurisdiction.
Medicaid, fee-for-service
A portion of Mississippi claims still runs through the Division of Medicaid directly, following its own coverage rules and timely-filing windows rather than a managed-care plan's.
MississippiCAN, managed care
Three Coordinated Care Organizations Magnolia Health, Molina Healthcare, and TrueCare each run their own portal, prior-authorization rules, and claim requirements.
Commercial carriers
Coded to national CPT and ICD-10-CM standards, but submitted against the specific coverage and documentation rules of whichever commercial payer is adjudicating the claim.
Plan lineup changed in 2025. Under the MississippiCAN contract effective July 1, 2025, UnitedHealthcare exited the program and TrueCare joined. Practices credentialed with the outgoing plan had to re-confirm enrollment with TrueCare, verify that active prior authorizations carried over, and watch for rejections tied to members moving between plans during the changeover.
Where cardiology claims go wrong
Cardiology billing tends to fail in specific, recurring ways rather than all at once and each one is easy for a biller splitting attention across ten specialties to miss.
-
Split-component echo reads. A technical- or professional-component modifier gets dropped when an echocardiogram is read somewhere other than where it was performed.
-
Undocumented nuclear studies. A perfusion study goes out without the documentation to support the radiopharmaceutical and the imaging performed.
-
Cath-and-intervention bundling. A diagnostic catheterization done in the same session as an intervention gets bundled incorrectly when the distinct-service modifier is missing.
-
Compounding A/R drift. In a high-volume imaging and interventional schedule, these small misses stack up into real dollars sitting in accounts receivable.
What we handle, end to end
Eligibility through appeals, run as one connected revenue cycle rather than a series of disconnected handoffs.
Common denial patterns here
A non-expansion state has its own denial fingerprint. These are the ones we see most.
-
Missing or expired prior authorization on managed-care imaging the single most common cause we see.
-
Medical-necessity edits on diagnostic testing, tracing back to a diagnosis code that doesn't fully support the service billed.
-
Coordination-of-benefits failures on dual-eligible patients whose Medicare and Medicaid coverage wasn't verified together.
-
Eligibility churn as patients move between CCOs or in and out of coverage, generating avoidable rejections when benefits aren't re-verified at the point of service.
Our revenue cycle workflow
Built to catch problems before a claim ever leaves the office.
-
1
Eligibility & benefit verification
Including Medicare/Medicaid coordination for dual-eligible patients and confirmation of managed-care plan assignment.
-
2
Charge capture & coding review
Checking modifier accuracy and the technical/professional split common in cardiac imaging and testing.
-
3
Prior authorization
Secured ahead of studies and procedures that require it under the applicable payer.
-
4
Claim creation, scrubbing & submission
Routed to the correct payer lane Medicare, Medicaid FFS, MississippiCAN, or commercial.
-
5
Claim-status monitoring
So rejections get corrected before they harden into denials.
-
6
Payment posting
Reconciled against contracted rates, with underpayments flagged rather than absorbed.
-
7
Denial analysis & appeals
Tracing each denial to a root cause so the same issue stops recurring.
-
8
A/R follow-up & reporting
Clear visibility into where revenue actually stands.

Work with a team that knows your payers
If managed-care authorizations, dual-eligible coordination, or A/R aging past 90 days are eating your week, it's usually fixable once you can see where claims are actually breaking down.
Frequently asked questions
Do you provide cardiology billing services in Mississippi?
Yes. We bill for cardiovascular practices across Mississippi as part of our nationwide coverage. We're headquartered in Dearborn, Michigan, and support Mississippi practices remotely, working inside whatever EHR and practice-management system a practice already uses.
Do you handle Medicaid billing for cardiology practices?
Yes both fee-for-service Medicaid through the Division of Medicaid and managed-care claims through the MississippiCAN Coordinated Care Organizations, currently Magnolia Health, Molina Healthcare, and TrueCare, each with its own portal, authorization rules, and claim requirements.
Do you support Medicare and commercial payer claims?
Yes. Fee-for-service Medicare claims for Mississippi providers are processed through MAC Jurisdiction H (Novitas Solutions), and we handle the major commercial carriers active in the state, coding to national CPT/ICD-10-CM standards while following each payer's own coverage rules.
Can you manage coding, denials, and A/R follow-up?
Yes coding, denial management, appeals, and accounts-receivable follow-up are core parts of the service. We trace denials to a root cause, correct and appeal where appropriate, and address the underlying pattern so it doesn't keep recurring.
Do you work with independent cardiologists and cardiology groups?
Yes independent cardiologists, cardiovascular groups, and multispecialty practices with a cardiology service line. Cardiology is the only specialty we bill for.
How do prior authorizations work for cardiac imaging?
Advanced imaging such as nuclear perfusion, cardiac CT/MRI, and some stress testing frequently requires prior authorization under managed-care plans. Requirements vary by plan and change periodically, so we confirm current policy with the specific payer before a scheduled study rather than assuming a prior rule still applies.
