# Holter Heart Monitor: Cost, Coverage, and What to Expect Source: https://ourhealthnetwork.com/procedure-costs/holter-heart-monitor Last reviewed: 2026-04-18 Data: CMS Hospital and Outpatient pricing, CPT/HCPCS code mapping ## Quick answer Medicare pays about $366 on average for an outpatient heart rhythm monitor across all wear lengths and device types. Commercial insurance and cash prices run two to four times higher. The monitor style (24-hour Holter, 14-day patch, or 30-day MCT) is the single biggest cost driver. ## What it is A heart rhythm monitor is a small, wearable device that records your heart's electrical activity outside of a doctor's office. Unlike a standard ECG in the clinic, which captures only 10 seconds, a monitor records for days or weeks so doctors can catch irregular rhythms that come and go. The goal is to link a symptom, like a fluttering chest, fainting spell, or skipped heartbeat, to what your heart is actually doing at that moment. There are several kinds, and the name you hear depends on the device style and how long you wear it. - **Fitting:** A technician places sticky electrodes on your chest or hands you a small adhesive patch. The visit usually takes 15 to 30 minutes. - **Wear time:** Ranges from 24 hours for a basic Holter to 30 days for a Mobile Cardiac Telemetry (MCT) monitor. Zio-style patches are typically worn for 7 to 14 days. - **Daily life:** You go about your routine. Most modern patches are waterproof or water-resistant, though you may need to keep older Holters dry. - **Data handling:** Some devices record continuously and are mailed back. Others transmit data wirelessly in real time to a monitoring center that flags dangerous rhythms. - **Report:** After the wear period, a cardiologist reviews the recording and sends a report to your doctor. The six Medicare codes on this page cover the main wear-length categories: short Holters (up to 7 days), extended patches (7 to 15 days), and long-term event or MCT monitors (up to 30 days). Which one your doctor orders depends on how often your symptoms show up. ## When it is done Doctors order a heart rhythm monitor when a standard office ECG looks normal but symptoms keep happening, or when they suspect an arrhythmia that only shows up occasionally. Your doctor may recommend this when: 1. You've had palpitations, skipped beats, or a fluttering sensation, and a standard ECG was inconclusive. 2. You've fainted or felt lightheaded and the cause is not clear. 3. You have known atrial fibrillation and your doctor wants to see how often it happens or how well a medication is working. 4. You've had a stroke with no clear cause, and the team wants to rule out silent afib. 5. You're on a heart rhythm medication that needs its effect measured over time. 6. A pacemaker or defibrillator decision is being considered and more data is needed first. The right wear length depends on how often your symptoms occur. Daily symptoms often call for a 24 to 48 hour Holter. Weekly symptoms are a better fit for a 14-day patch. Rare events, once a month or less, usually call for a 30-day event monitor or MCT. Alternatives your doctor might consider include an implantable loop recorder for very rare events, or, for straightforward rate checks, a consumer smartwatch as a rough screen (not a diagnostic replacement). ## What you pay Heart monitor pricing swings more on device type and wear length than on geography. A 24-hour Holter can cost under $200 cash-pay, while a 30-day MCT can run past $1,000. Commercial insurance typically pays an allowed amount of two to three times what Medicare pays for the same code, though your out-of-pocket depends entirely on your deductible and plan design. **If you're on Medicare (Part B):** - Medicare covers diagnostic heart monitors as outpatient services under Part B when ordered for a clinical reason. - You pay the annual Part B deductible first ($257 in 2025), then 20% coinsurance on the Medicare-allowed amount. - On a weighted average Medicare allowed amount around $465, your 20% share is $93, assuming you've already met your deductible. - A Medigap or Medicare Advantage plan usually covers the coinsurance portion, often leaving zero patient cost. **If you have commercial insurance:** - Most plans cover monitors when medically necessary, but the allowed amount is higher than Medicare, often in the $700 to $1,500 range for longer-wear devices. - Before your deductible is met, you may owe the full allowed amount. After it's met, coinsurance (usually 10% to 30%) applies. - Your out-of-pocket typically lands between $0 and $400. Plans with high deductibles can see the full device cost pass through. - Ask your plan if prior authorization is required. For 14-day patches and 30-day MCTs, it often is. **If you're uninsured or paying cash:** - Cash-pay and bundled prices vary widely by device. Negotiated rates for a 24 to 48 hour Holter typically run $200 to $400, a 14-day patch $400 to $900, and a 30-day MCT $800 to $1,500. - Many monitoring companies offer direct-to-consumer, cash-pay bundles with no insurance billing, and these are often cheaper than the itemized hospital price. - Ask whether a cash price buys the technical service only, or includes the physician's interpretation fee too. They are separate charges. - Hospitals are required to offer financial assistance; ask before committing to a hospital-based monitor. ## Anatomy of the bill A heart monitor bill almost always has at least two parts, and sometimes three or four. The technical service (the device and data processing) is billed separately from the physician who reads the report. You may also see a fitting-visit fee and any follow-up visit tied to the results. **Technical service fee:** The device, data capture, and analysis by the monitoring company or clinic. On a 14-day patch this runs about $193 Medicare and $400 to $900 cash-pay. On a 30-day MCT it runs about $688 Medicare and often more than $1,000 commercial. **Professional interpretation fee:** The cardiologist's review and report on the tracing. Medicare pays roughly $150 to $225 for the interpretation codes (93241, 93245). Some bills combine technical and professional into a single global charge (93241 or 93245). **Fitting or setup visit:** Usually a brief outpatient visit billed as an office visit (99213 or 99214). Medicare pays $90 to $140; commercial plans more. **Follow-up office visit:** After the results come back, you'll typically see your doctor to discuss. This is a separate office visit charge. **Coverage note:** Because these are diagnostic (ordered for a clinical reason) rather than screening, they generally bypass the preventive-services rules and are subject to your deductible and coinsurance. If the monitor finds nothing, you still pay; the fee is for the test, not the result. **Possible extras:** A chest X-ray, echocardiogram, stress test, or blood work is often ordered alongside or after the monitor. Each comes with its own bill. ## Cost by state State-by-state Medicare payments vary more than you might expect for a service that involves a small wearable device and a remote data review. Rhode Island tops the list at $819 per service, followed by New Hampshire ($811) and California ($730). Colorado sits at the low end at $139, though that reflects a single provider billing almost exclusively the lower-paying code 93271. Among higher-volume states, Maryland ($289) and the District of Columbia ($250) pay below the national average, while California, New Jersey, and Florida sit well above it. The highest-volume states are California, Illinois, Texas, New Jersey, and Florida, which together account for 18% of all services nationally. **Why costs vary by state:** - **Medicare geographic adjusters:** CMS applies a Geographic Practice Cost Index (GPCI) that raises rates in high-cost metros (California, the Northeast) and lowers them in rural states. - **Code mix:** States with more 30-day MCT billing (higher-paying 93229) show higher averages; states leaning on 93271 (30-day event) or 93243 (Holter analysis only) show lower averages. - **Commercial negotiation leverage:** In states with concentrated insurance markets, commercial payers negotiate monitor prices down; in fragmented markets, hospitals and monitoring companies hold the upper hand. - **Facility ownership:** States where cardiology practices own and bill the monitoring service directly often cost less than states where a hospital outpatient department bills it. ## Office vs facility This service is almost never performed in a facility setting. Medicare data shows 1,002,928 services billed in office-based settings compared to just 246 in facility settings, meaning hospitals bill this code well under 1% of the time. The real choice for most patients is not hospital versus office, but cardiology practice versus direct-to-consumer monitoring service. **When a cardiology practice makes more sense:** - You need the fitting visit, the monitoring, and the interpretation under one roof with one shared record. - Your symptoms are worrisome and you want a cardiologist managing the decision in real time. - You have traditional insurance that requires an ordering physician. **When a direct-to-consumer or mail-order service makes more sense:** - You're paying cash and want a transparent bundled price. - Your primary care doctor is comfortable ordering the monitor and reviewing results. - You want to avoid a separate office visit and prefer mail-in convenience. Hospital outpatient billing, when it does happen, is typically 30% to 100% more than an office-billed monitor for the same service. If a hospital is where your monitor was ordered, ask whether the monitoring company can bill the technical fee directly under office-based billing. ## Who performs the procedure Heart rhythm monitors are almost always ordered and interpreted by cardiologists. General cardiology accounts for 1,676 providers (the largest group), followed by interventional cardiology (396) and cardiac electrophysiology (257), the subspecialty that focuses specifically on heart rhythm disorders. Internal medicine shows up too (163 providers), but usually because an internist ordered the monitor and interpreted a straightforward tracing before referring anything complex to cardiology. - **Volume:** A cardiologist or EP who reads many monitors weekly will be faster and more accurate than one who reads a few a month. - **Subspecialty fit:** For recurrent palpitations, unexplained fainting, or suspected atrial fibrillation, an electrophysiologist is the right fit; for general screening, a cardiologist is fine. - **Board certification:** Verify through the American Board of Internal Medicine for cardiology and cardiac electrophysiology certification. - **Monitoring service used:** Ask which company processes the data. Established services (BioTelemetry, iRhythm, Preventice) have faster turnaround and better arrhythmia-detection algorithms. - **Turnaround:** Ask how long results take. A 14-day patch plus 3 to 7 days for analysis is typical; longer delays often signal a backlogged practice. - **Second opinion threshold:** If a monitor result leads to a recommendation for a pacemaker, defibrillator, or ablation, a second EP opinion is reasonable before proceeding. ## How to shop for the best price Monitors are one of the more shop-able services in cardiology because the device is the same whether it's mailed from a hospital or a monitoring company. 1. **Ask which CPT code will be billed.** The code (93229, 93247, 93243, 93271, 93241, or 93245) tells you exactly what you're buying and lets you compare prices head-to-head. Prices for different codes are not comparable. 2. **Request a Good Faith Estimate.** If you're uninsured or self-pay, federal law requires the provider to give you a written estimate in advance. Get it before you accept the monitor. 3. **Verify every billing party is in-network.** The ordering cardiologist, the monitoring service, and the interpreting physician can all be separate bills, and each must be in-network for full coverage. 4. **Compare cardiology-practice pricing to direct-to-consumer services.** Companies like iRhythm, BioTelemetry, and others will quote cash prices directly. Call two or three. 5. **Ask if a shorter monitor will work.** A 14-day patch costs less than a 30-day MCT. If your symptoms happen weekly, the patch is usually clinically appropriate and cheaper. 6. **Check if a global code will be billed.** A single global code (93241 or 93245) is often cheaper than separate technical and professional charges, and it reduces the number of bills you have to track. 7. **Ask about payment plans or financial assistance.** Hospitals are required to offer charity-care policies. Monitoring companies routinely offer installment plans without interest. Red flags to watch for: vague estimates that do not separate technical from professional fees, pressure to pick a 30-day MCT when your symptoms are frequent enough for a Holter, and any provider who cannot tell you upfront which CPT code will be billed. ## Surprise billing risks Heart monitors generate fewer shock bills than surgical procedures, but there are still traps. The most common is the split between the technical fee (the monitoring company) and the professional fee (the reading physician), where one is in-network and the other is not. Patients often assume both are covered because the cardiologist ordered it. **Most common surprise-billing sources:** - An out-of-network cardiologist interpreting a monitor ordered by your in-network primary doctor. - An out-of-network monitoring company used by an in-network cardiology practice; this is a real and common mismatch. - A separate, unexpected office-visit charge for the fitting or for the results discussion. - A hospital-based technical fee when you thought you were getting an office-based monitor (hospital billing runs higher). - Follow-on testing (echocardiogram, stress test) ordered from monitor results but billed as new services you did not preauthorize. **If you get a surprise bill:** - Do not pay until the bill is verified. Request an itemized bill with CPT codes, and match each line against your explanation of benefits. - If the bill is from an out-of-network provider you could not reasonably choose (like a remote reader), the federal No Surprises Act (in effect since January 2022) may protect you. File a complaint at cms.gov/nosurprises. - Call the billing office and ask if the charge can be reprocessed as in-network; for monitor services, this is often successful. - If that fails, file a complaint with your state insurance commissioner. ## Total recovery cost There is no recovery time for a heart monitor. You walk out of the fitting visit wearing it, and life continues normally. What patients don't always budget for is the workup and follow-up chain that often surrounds the monitor itself. The monitor is rarely the final step. **Add-on costs to budget for:** - **Cardiology consultation (if not already done):** $150 to $400 for a new-patient visit, depending on setting and insurance. - **Fitting or setup visit:** $90 to $250, usually billed as a level 3 or 4 office visit. - **Results follow-up visit:** Another $90 to $250, often billed separately from the monitor itself. - **Echocardiogram (if ordered):** $200 to $600 commercial, $175 to $300 Medicare. - **Stress test (if ordered):** $200 to $500 Medicare for basic exercise stress, more for nuclear or stress echo. - **Blood work:** $50 to $200 for thyroid panels, electrolytes, or other arrhythmia workup labs. - **Further testing or procedures:** If the monitor flags an abnormality, next steps may include an implantable loop recorder, an electrophysiology study, or ablation, each with its own major cost. - **Medication:** If the monitor confirms atrial fibrillation, lifelong blood thinners may follow. Generic apixaban or rivaroxaban costs $15 to $60 monthly with insurance; brand-name options run higher. Realistically, the monitor itself is often just 40% to 60% of the total episode cost when you add the cardiology visits and follow-on testing. Budget for the workup, not just the device. ## Variants of this procedure - 30-Day Mobile Cardiac Telemetry (MCT) - 7-Day Holter (Full Service) - Extended Holter, 3 to 7 Days - 14-Day Patch (Full Service) - 14-Day Continuous Patch Monitor - 30-Day Event Monitor ## Frequently asked questions ### How much does a heart monitor cost with insurance? Commercial insurance plans typically allow $700 to $1,500 for a 14-day patch or 30-day MCT monitor, and patient out-of-pocket lands between $0 and $400 depending on deductible status. Shorter Holters are less. Once your deductible is met, coinsurance of 10% to 30% applies on the allowed amount. ### Does Medicare cover heart monitors? Yes. Medicare Part B covers outpatient heart rhythm monitors when they're ordered for a clinical reason, such as palpitations, syncope, or suspected atrial fibrillation. You pay the Part B deductible ($257 in 2025) plus 20% coinsurance on the allowed amount, which Medigap often covers entirely. ### What's the difference between a Holter, a Zio patch, and an event monitor? A Holter is a traditional 24 to 48 hour (sometimes up to 7 day) recorder with wires and electrodes. A Zio-style patch is a small adhesive device worn 7 to 14 days continuously. An event monitor or MCT is worn 14 to 30 days and records longer, with MCT transmitting data in near-real time to a 24/7 center. Longer wear catches rarer symptoms but costs more. ### How long will I wear the monitor? Wear length is chosen based on how often your symptoms occur. Daily symptoms: 24 to 48 hour Holter. Weekly symptoms: 7 to 14 day patch. Monthly or less: 14 to 30 day event monitor or MCT. Your doctor matches the device to your symptom pattern. ### Is this outpatient or does it require a hospital stay? It's fully outpatient. There's no hospital stay. You visit a clinic for a brief fitting, wear the device at home during normal activities, and mail it back or attend a return visit at the end. Some patches you simply throw away after wear. ### How do I avoid a surprise bill? Ask in advance whether the monitoring company, the interpreting cardiologist, and the ordering practice are all in-network with your plan. Get the CPT code that will be billed in writing, and confirm whether the charge will be global (one bill) or split into technical and professional components. Request a Good Faith Estimate if you're paying cash. ### What's the cheapest way to get this procedure? For most patients, the cheapest path is a short 24 to 48 hour Holter through an in-network cardiology practice that bills a global code. If you're uninsured, direct-to-consumer monitoring services quote cash-pay bundled prices starting around $200 for short Holters, and often beat hospital-billed prices. ### Where does this cost data come from? Medicare figures come from the CMS Medicare Physician & Other Practitioners public data set, which reports average allowed amounts and payments across more than one million annual services nationally. Commercial and cash-pay ranges are estimates based on typical multiples of Medicare and published cash-pay rates from monitoring companies. ## Related - [All procedure cost concepts](https://ourhealthnetwork.com/procedure-costs) - [Find specialists who perform this procedure](https://ourhealthnetwork.com/find-doctors) - [Insurance plans that cover this procedure](https://ourhealthnetwork.com/tools/insurance-matcher)
