Medical Billing Services in Tennessee

TennCare operates under a longstanding federal waiver with a block-grant style financing arrangement found in no other state, and Tennessee has not expanded eligibility.

Billing here means working TennCare through its contracted managed care plans alongside Palmetto GBA for Medicare Part B, plus a commercial mix led by BlueCross BlueShield of Tennessee. Because Tennessee has not expanded Medicaid, practices here carry a higher share of uninsured and self-pay patients than neighbouring expansion states, which makes point-of-service collection and financial counselling a larger part of the revenue cycle.

Why jurisdiction matters

The same claim can pay in one state and deny in another

Medicare Part B claims in Tennessee are processed by Palmetto GBA under Jurisdiction JJ. Each contractor publishes its own Local Coverage Determinations, which means medical necessity criteria for the same procedure genuinely differ across jurisdiction lines.

Practices that expand across state lines, or that hire billing help unfamiliar with their jurisdiction, tend to discover this through denials rather than in advance. It is entirely avoidable, but only if someone is tracking the right contractor’s policies.

How TennCare actually pays

TennCare claims are adjudicated by contracted health plans, each maintaining its own payer ID, authorization criteria and fee schedule. Submitting to the state instead of the member's assigned plan is one of the most common Medicaid denials in Tennessee.

Billing in Tennessee

Last updated August 20, 2026

TennCare operates under a longstanding federal waiver with a block-grant style financing arrangement found in no other state, and Tennessee has not expanded eligibility. That is the fact worth building a workflow around here — more than any general best practice, because it changes who adjudicates the claim and under which rules.

Yes. TennCare is Tennessee's Medicaid program. TennCare claims are adjudicated by contracted health plans, each maintaining its own payer ID, authorization criteria and fee schedule. Submitting to the state instead of the member's assigned plan is one of the most common Medicaid denials in Tennessee. We maintain requirements at that level rather than treating Medicaid as a single generic payer, which is where most Medicaid denials originate.

Tennessee Part B claims are adjudicated by Palmetto GBA under Jurisdiction JJ. Jurisdiction JJ also covers Alabama and Georgia, so determinations issued there apply to Tennessee practices too. This matters more than most practices realize: each MAC issues its own Local Coverage Determinations, so a service payable in one jurisdiction can be denied for medical necessity in another with identical documentation. Alongside Medicare, BlueCross BlueShield of Tennessee is the commercial payer whose policy changes move the most volume for a typical Tennessee practice.

The dominant commercial payers in Tennessee include BlueCross BlueShield of Tennessee, Amerigroup and UnitedHealthcare Community Plan. Regional payers often carry the largest share of a local practice's volume while being the least standardized, which makes payer-specific claim edits more valuable here than generic scrubbing.

Tennessee has not expanded Medicaid. Because Tennessee has not expanded Medicaid, practices here carry a higher share of uninsured and self-pay patients than neighbouring expansion states, which makes point-of-service collection and financial counselling a larger part of the revenue cycle. It also changes which denials dominate: expansion states see more Medicaid plan authorization denials, while non-expansion states carry more uncompensated care and patient-responsibility balances that never reach a payer at all.

Yes. We work with practices across Tennessee — Nashville, Memphis, Knoxville and Chattanooga, and rural and independent practices outside them. Billing is performed remotely, so location within the state does not affect service. Payer mix does: outside the Nashville area, TennCare and UnitedHealthcare Community Plan typically carry a larger share of volume than they do in the metro.

Billing TennCare Tennessee runs Medicaid as managed care, so an MCO adjudicates the claim while the state sets policy. That decides the payer ID, the appeal route and the filing deadline — how Medicaid billing differs state by state covers what changes and why.

Billing Medicare in Tennessee Palmetto GBA adjudicates Part B claims for JJ, and publishes its own local coverage determinations for that jurisdiction. That is why an identical claim can pay in one state and deny in another. See what your MAC decides and how LCDs and NCDs work.
