If you or someone you love has been told they need a pacemaker — or is being evaluated for one — the first practical question after the diagnosis is almost always the same: will Medicare cover this?
The short answer is yes, Medicare does cover pacemaker surgery. But the complete answer involves understanding which part of Medicare pays, what your out-of-pocket costs will actually be, how prior authorization works in 2026, and whether a Medicare Advantage plan in Washington State changes anything about your coverage or your wallet.
As a licensed Washington State health insurance broker, I work with Medicare beneficiaries navigating exactly these kinds of high-stakes coverage questions. This article gives you a straight, detailed answer — not a vague summary — so you can walk into a conversation with your cardiologist and your insurance plan knowing exactly where you stand.
Pacemaker implantation is a covered Medicare benefit when it is medically necessary. That medical necessity standard is the key phrase — and in practice, for patients with documented arrhythmias, heart block, or other qualifying cardiac conditions, it is almost always met. Let’s walk through exactly how each part of Medicare handles this procedure.
Pacemaker surgery is almost always performed in a hospital setting — either as an inpatient procedure or, increasingly, as an outpatient procedure at a hospital outpatient department. This distinction matters significantly for your coverage and your costs.
Inpatient pacemaker surgery is covered under Medicare Part A. Part A covers your hospital stay, the operating room, nursing care, anesthesia administered by hospital staff, and the pacemaker device itself when you are formally admitted as an inpatient. In 2026, Medicare Part A inpatient coverage works as follows:
The vast majority of pacemaker implantations do not require a lengthy hospital stay. Most patients are discharged within one to two days, meaning the primary out-of-pocket exposure under Part A is the inpatient deductible — not extended daily coinsurance.
Outpatient pacemaker surgery — which is becoming more common as surgical techniques improve — is covered under Medicare Part B rather than Part A. This is a critical distinction because the cost-sharing structure is entirely different. Under Part B, you pay 20% of the Medicare-approved amount after your annual Part B deductible of $257 in 2026. For a procedure as significant as pacemaker implantation, that 20% coinsurance with no out-of-pocket cap under Original Medicare can be substantial.
This is precisely why understanding whether your procedure will be classified as inpatient or outpatient — and what your specific Medicare plan covers — matters before your surgery date, not after. For a full breakdown of how Parts A and B interact for Washington State beneficiaries, see our guide: Medicare Parts A, B, C & D in Washington State Explained.
Even when pacemaker surgery is classified as inpatient under Part A, Medicare Part B handles several related costs. Part B covers:
Under Part B, you pay 20% of the Medicare-approved amount for each of these services after your annual deductible. If your cardiologist does not accept Medicare assignment — meaning they charge more than Medicare’s approved rate — you may also face excess charges of up to 15% above the Medicare rate. In Washington State, most major cardiac centers and cardiologists do accept Medicare assignment, but it is worth confirming before your procedure.
Yes. The pacemaker device — the pulse generator and leads — is covered as part of the inpatient or outpatient procedure. Medicare does not require you to separately obtain or purchase the device. It is bundled into the facility’s covered costs for the procedure.
Modern pacemakers range considerably in sophistication. Single-chamber, dual-chamber, and biventricular devices (used for cardiac resynchronization therapy) are all covered when medically indicated. Leadless pacemakers — a newer implant-only device without traditional leads — are also covered by Medicare when appropriate criteria are met. Your cardiologist recommends the device type; Medicare coverage applies to the medically appropriate choice.
Under Original Medicare (Parts A and B), pacemaker surgery does not require prior authorization. CMS does not mandate prior authorization for this procedure under the traditional Medicare program. Your cardiologist determines medical necessity, documents it appropriately, and the procedure proceeds.
Under Medicare Advantage plans in Washington State, the answer is different — and this is where many beneficiaries are caught off guard. Medicare Advantage plans are permitted to require prior authorization for surgical procedures, and many do require it for pacemaker implantation. In 2026, new CMS rules provide stronger protections around how quickly plans must respond to prior authorization requests and what documentation they can demand — but the requirement itself can still apply.
If you are enrolled in a Medicare Advantage plan in Washington State and your cardiologist has recommended a pacemaker, contact your plan before scheduling surgery to confirm whether prior authorization is required and what the submission process looks like. A denial or delay in prior authorization should never delay emergency care — but for scheduled procedures, this step protects you from unexpected billing. Our detailed guide covers exactly how this works: Medicare Prior Authorization in Washington 2026.
If a pacemaker is implanted on an emergency basis — for example, following a sudden cardiac event or complete heart block — Medicare covers the procedure regardless of prior authorization status. Emergency care is always covered under Medicare, and no plan can require advance authorization for a genuine medical emergency. Both Original Medicare and Medicare Advantage plans must cover emergency services under federal law.
Pacemaker surgery is one of the most significant procedures Medicare beneficiaries face. These guides help you understand exactly how your plan works — before you need it.

Medicare covers pacemaker surgery — but “covered” does not mean “free.” Understanding your realistic out-of-pocket exposure before the procedure gives you time to plan, to review your supplemental coverage, and to make sure your plan is the right fit for the care you need.
Original Medicare (Parts A and B) has no annual out-of-pocket maximum. That means your cost exposure, in theory, is uncapped. For pacemaker surgery, here is what the realistic cost picture looks like:
This is where Medicare Supplement plans — Medigap — provide their most obvious value. Washington State Medigap plans are standardized, which means Plan G in Spokane covers the same benefits as Plan G in Seattle. For a pacemaker procedure, here is what the most common Washington Medigap plans cover:
For Washington State Medicare beneficiaries who are managing a cardiac condition — or who have risk factors that suggest they may need significant medical care — a comprehensive Medigap plan is worth taking seriously. The premium you pay monthly is predictable. The cost of an uncovered major procedure is not. Our full comparison of Washington Medicare plan options is here: Washington Medicare Plan Options for 2026.
If you are enrolled in a Medicare Advantage plan in Washington State, your pacemaker surgery coverage depends on your specific plan’s structure rather than Original Medicare’s cost-sharing rules. Medicare Advantage plans must cover everything Original Medicare covers — including pacemaker surgery — but they apply their own deductibles, copays, coinsurance, and out-of-pocket maximums.
Key things to know about Medicare Advantage and pacemaker surgery in Washington:
For Washington State beneficiaries on Medicare Advantage, comparing your plan’s inpatient cost-sharing and out-of-pocket maximum against your actual financial exposure is the most important step you can take before a scheduled procedure. See our full Medicare Advantage guide for Washington: Medicare Advantage Plans in Washington State.
A pacemaker is not a one-time procedure. Pacemaker batteries typically last seven to twelve years, at which point the pulse generator requires replacement — a separate surgical procedure that Medicare also covers under the same Part A and Part B framework. The leads, which connect the device to the heart, may last decades but can also require replacement or revision over time.
Ongoing costs that Medicare Part B covers after implantation include:
Factoring in these long-term costs when evaluating your Medicare plan — not just the immediate surgical coverage — is part of making a genuinely informed plan decision.
A note from a Washington Medicare broker: Pacemaker surgery is one of those moments where the gap between a well-chosen Medicare plan and a poorly-chosen one becomes very real, very fast. The difference between Original Medicare with no Medigap and a comprehensive Plan G for a procedure like this can be thousands of dollars out of pocket. If you have a cardiac condition and haven’t reviewed your Medicare coverage recently, that review is overdue — and it costs you nothing to do it with a licensed broker.
These are the questions Washington State Medicare beneficiaries ask most often about pacemaker coverage, costs, and plan choices. Answered directly — no boilerplate, no runaround.
Yes Medicare covers pacemaker implantation when it is medically necessary — and for patients with documented arrhythmias, heart block, or other qualifying cardiac conditions, that standard is almost always met. The procedure is covered under Medicare Part A when performed on an inpatient basis, and under Medicare Part B when performed in a hospital outpatient setting. The pacemaker device itself — including the pulse generator and leads — is included in the covered procedure costs. You do not purchase the device separately.
Medicare Part A covers your inpatient hospital costs when you are formally admitted for pacemaker surgery. This includes the operating room, nursing care, anesthesia administered by hospital staff, and the pacemaker device. In 2026, the Part A inpatient deductible is $1,676 per benefit period. After that deductible, Medicare covers 100% of approved inpatient costs through day 60 of your stay. Since most pacemaker implantations require only one to two days in the hospital, the deductible is typically your primary out-of-pocket exposure under Part A.
This distinction matters more than most people realize. Inpatient surgery is covered under Part A — your main exposure is the $1,676 inpatient deductible. Outpatient surgery, which is increasingly common as techniques improve, falls under Part B instead. Under Part B you pay 20% of the Medicare-approved amount with no out-of-pocket cap under Original Medicare. For a procedure as significant as pacemaker implantation, that uncapped 20% coinsurance can add up to a meaningful dollar amount.
The hospital — not you — typically determines the admission status based on clinical criteria. It is worth asking your care team before surgery whether you will be formally admitted as inpatient, because the answer directly affects your bill.
It depends Under Original Medicare (Parts A and B), pacemaker surgery does not require prior authorization. Your cardiologist documents medical necessity and the procedure proceeds. Under Medicare Advantage plans in Washington State, most plans do require prior authorization for pacemaker implantation. If you are on a Medicare Advantage plan, contact your plan before scheduling the procedure — not after. A prior authorization denial for a scheduled surgery is one of the most stressful and avoidable coverage problems Washington beneficiaries face.
Under 2026 CMS rules, Medicare Advantage plans must respond to standard prior authorization requests within 7 calendar days and expedited requests within 72 hours. Emergency pacemaker surgery is covered immediately regardless of authorization status.
Under Original Medicare with no supplemental coverage, your realistic out-of-pocket costs for pacemaker surgery include:
Original Medicare has no annual out-of-pocket maximum. For a major procedure like pacemaker surgery, that unlimited exposure is the strongest argument for carrying a Medicare Supplement (Medigap) plan.
Yes A Medicare Supplement (Medigap) plan significantly reduces your out-of-pocket exposure for pacemaker surgery. Plan G — the most comprehensive option available to new Medicare enrollees in Washington State — covers the Part A inpatient deductible, Part A coinsurance, Part B coinsurance, and Part B excess charges. After your $257 annual Part B deductible, Plan G covers essentially everything Medicare approves for the procedure.
Washington State has stronger Medigap guaranteed-issue protections than most other states, which means your options for obtaining supplemental coverage may be broader than you expect. For a comparison of Washington Medigap plans in 2026, see Washington Medicare Plan Options for 2026.
Medicare Advantage plans must cover everything Original Medicare covers — including pacemaker surgery. But the cost-sharing structure is different. Instead of the Part A deductible and uncapped Part B coinsurance, you pay your plan’s specific copays or coinsurance for inpatient hospital stays. All Washington Medicare Advantage plans have an annual out-of-pocket maximum — set at no more than $9,350 for in-network services in 2026 — which caps your total exposure in a way Original Medicare alone does not.
Key things to verify with your Advantage plan before pacemaker surgery:
Yes Pacemaker batteries typically last seven to twelve years, after which the pulse generator requires replacement surgery. Medicare covers this procedure under the same Part A and Part B framework as the original implant — it is treated as a separate covered surgical procedure when medically necessary. The leads connecting the pacemaker to the heart can also require replacement or revision over time, and Medicare covers those procedures as well when medically indicated.
Yes Medicare Part B covers all pacemaker-related follow-up care, including regular cardiology visits, in-office device interrogation and programming, and remote monitoring. Most modern pacemakers transmit data wirelessly to your cardiologist’s office — Medicare pays for the physician review of that transmitted data as an ongoing covered service. You pay 20% of the Medicare-approved amount for these services under Original Medicare, subject to your annual Part B deductible.
It depends Both pathways cover the procedure — but each comes with tradeoffs that matter for a cardiac patient specifically.
Original Medicare + Plan G Medigap gives you the broadest provider access — any cardiologist or cardiac center that accepts Medicare, anywhere in the country — with minimal out-of-pocket exposure after your annual deductibles. There are no network restrictions and no prior authorization requirements. For someone managing a serious cardiac condition who values freedom of provider choice, this combination is hard to beat.
Medicare Advantage offers a capped annual out-of-pocket maximum and often lower monthly premiums — but comes with network restrictions, prior authorization requirements, and cost-sharing that varies significantly by plan. An HMO Advantage plan that doesn’t include your cardiologist in-network is a serious problem when a procedure is on the table.
The right answer depends on your specific health situation, your doctors, and your county’s available plans. A licensed Washington broker can model both scenarios against your actual circumstances at no cost to you.
