Indirect Mitral Valve Repair via Coronary Sinus
CPT 0345T
Reported when a cardiologist places a coronary-sinus annuloplasty device to indirectly reduce mitral valve leakage in a heart-failure patient.
No national payment amount
Carrier-priced: no national payment amount.
Did Medicare pay separately for CPT 0345T in Q1 2026?
Not at a published national rate. CPT 0345T carries status C (carrier-priced) in the Q1 2026 release. Your Medicare Administrative Contractor prices this code case by case, usually after reviewing documentation. Treat the blank amount as unpriced, not as $0.
Common questions
Why is there no payment amount for 0345T?
Its status indicator is C (carrier-priced). Your Medicare Administrative Contractor prices this code case by case, usually after reviewing documentation. The blank is deliberate: the amount is either unknown or paid under another provision, so reading it as $0 would be wrong.
Why would a Medicare claim for 0345T be denied or paid less?
Each item below comes from a CMS indicator on this page — not general billing advice.

Payer-specific coverage and documentation rules live outside these files, so a claim that clears every check here can still be denied on other grounds.
When does this rate change?
CMS publishes a fee schedule release every quarter (January, April, July, October), and each is versioned here. See what changed each release, or get an email when a new release moves rates.

What is a 0345T visit in patient-friendly terms?
In plain terms: A catheter-based treatment for a leaky mitral heart valve that works indirectly - rather than clipping or repairing the valve's leaflets directly, a device is placed in the coronary sinus, a vein that runs along the back of the mitral valve's supporting ring, and cinched to reshape and tighten that ring from the outside. It is a different technique from the more commonly known leaflet-clipping procedures, and is generally used in patients with heart failure whose mitral leak stems from a stretched, weakened heart rather than a damaged valve itself. Think of a patient with heart failure whose heart chamber has stretched enough to pull the mitral valve open and let blood leak backward, but who is not a good candidate for open surgery. Rather than fixing the valve leaflets themselves, a catheter delivers a device into a vein behind the valve and tightens it like a cinch, indirectly closing the leak. You'll typically see CPT 0345T on a bill or explanation of benefits (EOB) when a clinician performs or bills for this service.
How this amount is computed
amount = (work RVU × work GPCI + PE RVU × PE GPCI + MP RVU × MP GPCI) × conversion factor. National amounts use GPCI = 1.000. To price an RVU figure of your own, use the RVU-to-dollars converter.
| Component | RVU |
|---|---|
| Work RVU | blank |
| Practice expense RVU (non-facility) | blank |
| Practice expense RVU (facility) | blank |
| Malpractice RVU | blank |
Every rate combines three parts: work (the clinician’s time, skill and effort), practice expense (office overhead — higher when the service is done in a doctor’s own office), and malpractice (the share of liability-insurance cost). A blank means CMS publishes no national number for that part. Read it as unknown, and never as zero.

Source & method
This is computed from CMS's Medicare Physician Fee Schedule Q1 2026 release (schedule pfs, effective January 2026). National amounts apply a GPCI of 1.000 and leave sequestration off. The status indicator decides payability, never the RVU values, so a blank RVU stays blank. Releases are immutable: a rate retrieved for a past quarter always reflects that release. Commercial and cash-pay figures anywhere on this page are arithmetic on the Medicare amount, using commonly cited reimbursement ranges. They're illustrative, and no nationwide claims database stands behind them.
