Medicare LCD coverage for echocardiography and stress testing, by MAC.
"The LCD says" is close to meaningless in cardiac imaging, because Medicare Local Coverage Determinations for echocardiography and stress testing are written and maintained per Medicare Administrative Contractor, not nationally. We confirmed this directly against the CMS Coverage Database: echocardiography and TEE alone have separate, independently-dated billing-and-coding articles from at least six different MACs.
Key takeaways
- Cardiac echo LCDs are MAC-specific, confirmed directly. Palmetto GBA, CGS, Novitas, Noridian, Wellpoint Federal, and NGS each maintain separate articles.
- Find your MAC first, then pull that MAC's specific article — not a generic search result, which may surface a different jurisdiction entirely.
- These are Medicare Part B policy only — commercial payers publish and follow their own coverage bulletins.
Confirmed jurisdiction variance
Every article below was retrieved directly from the CMS Coverage Database. The article ID, MAC, and effective date differ across every row — this isn't a hypothetical, it's the actual current state of cardiac echo coverage policy.

⚠️ This build confirmed the article IDs, MACs, and effective dates above directly against the CMS Coverage Database. The full covered-diagnosis lists and frequency limits inside each article were not independently re-verified here — CMS's article pages blocked automated retrieval during this build — so pull and read the specific article text yourself before finalizing an order-set rule or coverage-check workflow against it.
Find your MAC before you search
The practical workflow: identify which MAC processes your Part B claims first — it's listed on your enrollment paperwork and remittance advice, and CMS publishes a jurisdiction map — then go to that MAC's specific published articles for the study in question. A generic web search for "echocardiography LCD" will surface whichever article ranks best, which is not necessarily your MAC's, and building an order-set rule off the wrong jurisdiction's policy is exactly how a genuinely covered diagnosis still ends up denied.
Medicare Part B only
These LCDs and articles govern Medicare Part B claims exclusively. They don't apply to Medicare Advantage plans, which often run their own medical policy even when administered alongside traditional Medicare, and they don't apply to commercial payers at all — those publish independent medical policy bulletins that sometimes reference Medicare criteria as a starting point but aren't bound by it. When a commercial payer denies a cardiac imaging claim, the relevant Medicare LCD is useful context for understanding typical coverage logic, but it is not the governing policy and shouldn't be cited as though it were.
Build your coverage-check step at order entry around your specific MAC's article, saved and reviewed on a set schedule — quarterly is reasonable — rather than a bookmark from whenever the practice last looked it up. Article effective dates in the table above range from 2023 to 2026 across different MACs, which shows how differently these get revised.
Not sure which MAC's coverage rules actually apply to your claims?
We'll identify your jurisdiction's specific LCDs for your highest-volume cardiac imaging studies and build the coverage check into your order workflow.
Frequently asked questions
How do I find out which MAC processes our Medicare Part B claims?
Your MAC is determined by your practice's state and is listed on your Medicare enrollment documentation and remittance advice; CMS also publishes a jurisdiction map. Once you know your MAC, search that MAC's specific published LCDs and billing-and-coding articles for the study in question rather than a generic search result that may return a different MAC's policy.
Do LCDs apply to commercial payers too?
No — Medicare LCDs are Medicare Part B policy only. Commercial payers publish their own medical policy bulletins, which sometimes reference Medicare coverage criteria as a starting point but are not bound by it and often diverge in frequency limits, covered diagnoses, or prior authorization requirements. Treat a Medicare LCD as context for a commercial claim, never as the governing policy.
How often do LCD articles change?
There's no fixed schedule — MACs revise their articles as clinical guidance, coding, or CMS national policy changes, and effective dates for the same topic vary MAC to MAC, sometimes by months or more than a year. Check the specific article's effective and last-updated dates each time you rely on it rather than assuming it's still current from a prior review.
Verify before billing. LCD articles are revised on an ongoing basis by each MAC. Article IDs, MACs, and effective dates above were confirmed against the CMS Coverage Database at the time of writing; re-verify current status and full article text before relying on any of them operationally.
