Denial driver
Wrong MCO auth rule
How we prevent it
Diagnosis and study matched to the patient's specific TennCare plan policy
Radiology billing · Tennessee
Radiology billing services in Tennessee live or die on one thing a generalist misses: TennCare is not one payer but three managed-care plans, each with its own prior-authorization rulebook — and 247MBS has billed imaging against that variance since 2005.
From Vanderbilt's reading rooms in Nashville to imaging suites in Memphis, Knoxville, and Chattanooga, we bill every interpretation and every scan against the right TennCare MCO and Palmetto GBA policy, with a dedicated account manager, a free real-time dashboard, and HIPAA-compliant, SOC 2 Type II workflows on every claim.
Tennessee's imaging economy runs along its three grand divisions. Vanderbilt University Medical Center and the HCA/TriStar network anchor Middle Tennessee around Nashville; Methodist Le Bonheur and Regional One serve Memphis in the west; the University of Tennessee Medical Center and Ballad Health cover Knoxville and the east; and Erlanger anchors Chattanooga in the southeast. Around those systems sit freestanding MRI and CT centers, mobile operators, and interventional groups reading under hospital contract. Every one of those claims turns on the same first question: does the group interpret only, own the equipment, or both? Interpret only, and the read carries the professional component with modifier 26; own the scanner and the interpretation, and the study bills global. Get the component wrong in a provider-based department and the payer recoups after the fact.
For Medicare Part B, Tennessee sits under Palmetto GBA, Jurisdiction M, whose Local Coverage Determinations decide which diagnoses make an advanced study medically necessary. A read that skips the LCD match does not pay on the quality of the dictation alone. Our coders map the ordering diagnosis to the covering Palmetto policy before the claim leaves the queue — a step a general billing company usually skips.
TennCare, Tennessee's Medicaid program, runs almost entirely through managed care. Three statewide MCOs — BlueCare (BlueCross BlueShield of Tennessee), UnitedHealthcare Community Plan, and Wellpoint (Elevance) — carry the risk, with TennCare Select covering specific populations. For a radiology group that means an advanced-imaging study is not billed to "TennCare"; it is billed to whichever plan the patient carries, under that plan's prior-authorization and radiology-benefit-manager rules. The three plans do not authorize the same way, and a CT that clears one MCO's policy can reject under another's for the identical diagnosis.
That variance is compounded by a sequencing trap: in Tennessee you enroll first and contract second, and a radiologist who bills before both steps close will see the claim deny regardless of how clean the read is. The east-to-west spread matters too — a group reading for Ballad Health in the Tri-Cities and a group reading for Memphis hospitals may see the same three plans behave differently in practice, because the local provider networks and referral patterns are not identical. Commercial and Medicare Advantage volume adds its own RBM layer on top of all of it. We verify eligibility, identify the exact MCO, confirm that plan's authorization requirement, and secure the prior authorization pre-scan, so the interpretation is billable the day it is dictated rather than parked in an aging bucket.
| Tennessee payer fact | Detail |
|---|---|
| Medicaid program | TennCare |
| Delivery model | Managed care (3 MCOs) + TennCare Select |
| Major plans | BlueCare (BCBST), UnitedHealthcare, Wellpoint (Elevance) |
| Medicare Part B MAC | Palmetto GBA, Jurisdiction M |
| Appeal window | ~90 days (medical appeal; verify) |
| Medicaid enrollment | ~1.39 million |
Every Tennessee study is a chain of billing decisions our team owns from order to remittance. Codes belong in a table, not a sentence — here is the logic we apply on each read:
| Billing element | How it drives payment in Tennessee |
|---|---|
| Professional vs technical | Modifier 26 for the read, TC for the equipment; global only when one entity owns both |
| CT / MRI / PET | 70450, 72148, 74177, 78815 cleared against the covering LCD and the MCO's RBM policy |
| Contrast and supervision | With/without-contrast codes and supervision level tied to the written order |
| Repeat and distinct reads | 76 same-physician repeat, 77 different physician, 59 to unbundle only when genuinely distinct |
| Laterality | RT/LT and modifier 50 on paired studies |
Behind those decisions sit the numbers that matter: a 99% clean-claim rate, roughly 99% net collections, under-25-day A/R, up to 40% fewer denials, and 90% of denials recovered on appeal, with claims out the door inside 24 hours. Those are the compliant benchmarks a professional imaging team should hold you to.

Whether you run a hospital-based group reading for Vanderbilt or TriStar departments, a freestanding center in Knoxville, an interventional practice in Memphis, or a teleradiology group covering the state's rural east and west, the billing has to match your footprint and the patient's plan. Teleradiology adds a licensure layer — a radiologist reading a Tennessee study from another state must be licensed and, where required, enrolled where the patient sits, and the claim must reflect the correct rendering location. We build the professional/technical split per site of service and route each claim to the correct TennCare MCO, so the office that owns its scanner bills global, the group that only interprets bills the 26 component, and neither is over- or under-stated. One group, three plans, one accountable billing team.
Revenue here rarely walks out the front door — it drains through preventable edits a volume-first biller never catches, and TennCare's three-plan structure multiplies the ways a claim can go wrong:
Wrong MCO auth rule
Diagnosis and study matched to the patient's specific TennCare plan policy
LCD / medical-necessity mismatch
Ordering diagnosis matched to the covering Palmetto M policy before billing
Wrong 26/TC split
Component billed to match the actual site of service
No RBM authorization
Advanced-imaging auth secured before the scan, per plan
NCCI bundling & duplicate reads
59 used only where truly distinct; 76/77 to defend legitimate repeats
Your revenue review ranks these by dollars lost across your Tennessee sites and by plan, so the biggest leak gets fixed first.
Groups across the state outsource radiology billing because a general biller treats every TennCare claim the same — and the three MCOs are not the same. As a medical billing services company built specifically around imaging, we carry the per-plan RBM workflows, the Palmetto LCD map, and the component-split logic before your first claim goes out. Outsourcing here is not about cutting a check to a cheaper billing company; it is about handing the read to a team that already tracks each MCO's authorization rulebook. We run the full cycle:
— the exact TennCare MCO and its auth requirement confirmed pre-scan
— worked against the LCD and the plan's RBM policy inside the appeal window, not just resubmitted
— radiologists enrolled then contracted across each TennCare plan and commercial carriers
— the whole imaging cycle owned end to end
All of it lives inside our radiology revenue cycle practice, and it complements the broader Tennessee medical billing services our team runs statewide — one billing services company, one dashboard, backed by a 98% client retention rate.
We bill hospital-based radiology groups reading for the state's academic and community systems, freestanding MRI and CT centers, outpatient and mobile imaging operators, interventional radiology practices, and teleradiology groups — in Nashville, Memphis, Knoxville, Chattanooga, and Clarksville, and out to the rural counties those metros serve. Own the equipment, only the read, or both, and we bill the professional and technical pieces to match.
Medical billing for radiology in Tennessee protects imaging revenue the moment the patient's actual plan is identified — not "TennCare," but the specific BlueCare, UnitedHealthcare, or Wellpoint policy that governs the authorization. 247MBS clears each advanced study through that plan's radiology-benefit manager before the scan, maps the ordering diagnosis to the covering Palmetto Jurisdiction M policy, and splits the professional read from the technical component to match whether you read for Vanderbilt, Ballad Health, or your own scanner. That discipline holds a 99% clean-claim rate and A/R under 25 days across Nashville, Memphis, Knoxville, and Chattanooga groups. See the gaps first — request a revenue review.
Start with a revenue review: we'll review your 26/TC splits, your per-MCO advanced-imaging authorizations, your Palmetto LCD matches, and your aging TennCare A/R, then show you what a focused imaging team can recover.
Each city page covers the local payer mix, the practices we bill for there, and the denials we prevent.
Each plan — BlueCare, UnitedHealthcare, and Wellpoint — sets its own prior-authorization and RBM rules, so we verify the patient's exact MCO first and bill the study to that plan's policy, rather than treating "TennCare" as a single payer and inviting a rejection.
Yes. Tennessee's Medicare Part B claims run under Palmetto GBA M, and its Local Coverage Determinations govern medical necessity. We check the ordering diagnosis against the covering policy before the interpretation is submitted.
Yes. We enroll the radiologist and then complete each plan's contracting step so claims are not billed before both are in place — the sequence that quietly drives avoidable TennCare denials.
Whether you are a solo practice or a multi-site group, we bill Radiology across Tennessee under one dedicated account manager and a live dashboard — and treat every counted unit, authorization and appeal as recoverable revenue until it is safely paid.
