Tennessee Part A Buy-In: How QMB Covers the Premium Without 40 Work Quarters

Most Medicare beneficiaries get Part A for free because they or their spouse paid Medicare taxes for at least 40 quarters of employment. But for immigrants who arrived later in life, people who worked in jobs not covered by Social Security, or those who simply didn't accumulate enough credits, the Part A premium in 2026 is $311 per month (30–39 quarters) or $565 per month (fewer than 30 quarters). On a fixed income of $950 a month, that's not a gap — it's a wall.

Tennessee has a mechanism that brings the wall down entirely.

What Part A Buy-In Means

Tennessee is classified as a Part A Buy-In State under Section 1818(g) of the Social Security Act. The practical effect: a low-income Tennessee resident who qualifies for QMB can enroll in Medicare Part A at any time during the calendar year, with TennCare paying the entire Part A premium.

In "Group Payer States" — states without a buy-in agreement — someone without premium-free Part A can only sign up during the General Enrollment Period (January 1 through March 31). If they miss that window, they wait until the next year, and late enrollment penalties stack up.

Tennessee's buy-in agreement eliminates both constraints. No enrollment window. No penalties.

How the Process Works

The process begins with SSA and TennCare, with CMS handling the buy-in record:

Step 1: Conditional application at Social Security. Your parent visits a local SSA field office and files an application for Medicare Part A (and Part B if not already enrolled). They sign a statement indicating they want Part A enrollment only if approved for QMB by the state. This is called a "conditional application" and is documented in SSA's Program Operations Manual System (POMS) at HI 00801.140.

Step 2: MSP application at TennCare. Your parent (or you, as authorized representative) submits a Medicare Savings Program application through TennCare Connect — online, by phone at 1-855-259-0701, or at a county DHS office.

Step 3: Automatic buy-in. When TennCare approves QMB, it transmits a buy-in record to CMS. CMS activates Part A coverage and Tennessee assumes direct financial liability for the premium. Your parent is never billed by CMS or Social Security for the Part A premium.

The timing of Part A activation depends on the agency steps. Follow up with SSA or TennCare if the enrollment or premium status does not update.

What to Say at the SSA Office

Local Social Security field office staff don't process QMB conditional Part A applications every day. If the clerk attempts to restrict filing to the General Enrollment Period or demands upfront premium payment, reference POMS HI 00801.140 by name. This is the SSA procedure that authorizes year-round conditional Part A enrollment in buy-in states.

Having the POMS reference and a written statement that your parent is applying conditionally pending QMB approval in Tennessee usually resolves any confusion at the counter.

QMB Covers Both Premiums

Once QMB is approved with Part A buy-in, TennCare pays:

• The Part A premium ($311 or $565/month depending on work quarters)
• The Part B premium ($202.90/month)
• All Medicare deductibles, copays, and coinsurance

For someone who was paying $565 for Part A and $202.90 for Part B out of a $950 monthly income, QMB with buy-in turns $767.90 in monthly premiums into $0. The full monthly income stays in the household.

Who This Helps

Part A buy-in primarily serves:

• Long-term legal immigrants who worked fewer than 40 quarters in the U.S.
• People who spent careers in state or local government jobs not covered by Social Security
• Spouses who don't qualify on their own work record and whose spouse hasn't filed for benefits yet

Eligibility follows the same QMB limits: gross income up to $1,350/month for an individual, with the $20 disregard reflected in that published limit, and countable resources at or below $9,950.

The Tennessee Medicare Savings Programs & Extra Help Guide covers the conditional application process in detail, including what documents to bring to the SSA office, how to track the buy-in through both agencies, and what to do if the conditional application stalls.
