The VA rates atrial fibrillation under 38 CFR 4.104, Diagnostic Code 7010, at either 10 percent or 30 percent. You get 30 percent when your AFib is confirmed by ECG and you required five or more treatment interventions in a year, meaning IV medication adjustment, electrical cardioversion, or catheter ablation. You get 10 percent when the ECG-confirmed AFib required one to four such interventions, or when it is controlled with continuous oral medication or vagal maneuvers. A rating above 30 percent for AFib is possible, but only when the arrhythmia has produced measurable cardiac impairment rated under the General Rating Formula for the heart, or when a separate service-connected condition such as stroke residuals is rated alongside it.
AFib is the most commonly claimed condition under DC 7010. If you want the broader picture of how the VA rates all cardiac arrhythmias, including bradycardia under DC 7009 and ventricular arrhythmias under DC 7011, read the arrhythmia rating guide. This page covers what that guide left out: the AFib-specific evidence, the paperwork that decides whether you land at 10 or 30, and the secondary claims that attach to an AFib diagnosis.
The DC 7010 rating tiers for 2026
| Rating | Criteria |
|---|
| 30% | Confirmed by ECG, with five or more treatment interventions per year (intravenous pharmacologic adjustment, cardioversion, and/or ablation) |
| 10% | Confirmed by ECG, with one to four treatment interventions per year; or confirmed by ECG with either continuous use of oral medication to control the rhythm, or reliance on vagal maneuvers to control it |
These criteria took effect November 14, 2021, when the VA rewrote the cardiovascular portion of the rating schedule. Before that date, DC 7010 counted episodes documented by ECG or Holter monitor: more than four episodes a year earned 30 percent, and one to four episodes, or permanent AFib, earned 10 percent.
The change matters. Counting episodes favored veterans with frequent, self-terminating paroxysmal AFib. Counting interventions favors veterans who get actively treated. A veteran with 20 documented paroxysmal episodes a year who manages every one of them at home with a pill-in-the-pocket dose and vagal maneuvers now sits at 10 percent, where the old rules would have supported 30.
If your claim was received before November 14, 2021, the VA is required to evaluate you under both the old and new criteria and apply whichever produces the higher rating. If you already hold a DC 7010 rating assigned under the old episode-counting rules, that rating is not automatically reduced. The new criteria apply when you file for an increase or when a scheduled re-examination results in a new evaluation, and even then the VA cannot reduce a stabilized rating without evidence of actual improvement.
What counts as a treatment intervention
The regulation defines this precisely. A treatment intervention occurs whenever a symptomatic patient requires intravenous pharmacologic adjustment, cardioversion, and/or ablation for symptom relief. Three things, and only those three.
Counts as an intervention:
- Electrical (direct current) cardioversion, whether elective or emergent
- Chemical cardioversion with IV medication such as amiodarone, ibutilide, or procainamide
- IV rate control given in an ED or inpatient setting for a symptomatic episode (IV diltiazem, IV metoprolol)
- Catheter ablation, including pulmonary vein isolation, cryoablation, and pulsed field ablation
- Surgical or hybrid ablation such as a Maze or convergent procedure
- AV node ablation
Does not count as an intervention:
- Refilling or continuing a daily oral antiarrhythmic or rate-control prescription
- A routine cardiology or anticoagulation clinic visit
- Wearing a Holter monitor, event monitor, or loop recorder
- An echocardiogram, stress test, or lab draw
- Anticoagulation alone (warfarin, apixaban, rivaroxaban), which prevents stroke but does not treat the rhythm
- A self-administered pill-in-the-pocket dose taken at home
- Vagal maneuvers, which support the 10 percent tier but are not interventions
The practical consequence is that the 30 percent tier is hard to reach with well-controlled AFib. Five interventions in a twelve-month period usually means a bad year: multiple ED visits with IV rate control, one or more cardioversions, and possibly an ablation. Veterans whose AFib is genuinely that active often do not realize their ED records already document the five events, because those visits are scattered across different facilities and never compiled into a single list.
Paroxysmal, persistent, and permanent AFib in a VA claim
Cardiology classifies AFib four ways, and each type behaves differently inside DC 7010.
| Type | Clinical definition | Typical DC 7010 outcome |
|---|
| Paroxysmal | Episodes start and stop on their own, usually within 7 days | 10% if managed with daily medication or vagal maneuvers; 30% only if five or more interventions in a year |
| Persistent | Episodes last more than 7 days and require cardioversion or drugs to convert | Most likely path to 30%, because each conversion is an intervention |
| Long-standing persistent | Continuous AFib for more than 12 months, with rhythm control still being attempted | Often 30% in the year of an ablation plus cardioversions, 10% after |
| Permanent | Rhythm control has been abandoned; rate control and anticoagulation only | 10% under the continuous oral medication clause |
Permanent AFib is the counterintuitive one. A veteran in AFib every minute of every day, on a beta-blocker and an anticoagulant for life, with no further procedures planned, receives 10 percent, because the regulation measures intervention frequency rather than the constancy of the arrhythmia. This is where the General Rating Formula becomes the more important path, discussed below.
Documenting AFib: monitors, strips, and what the rater needs to see
DC 7010 begins with the words "confirmed by ECG." A rater who cannot find a tracing in the file has grounds to deny service connection entirely, no matter how many notes say "history of AFib."
Twelve-lead ECG. The strongest single piece of evidence. If you have ever been captured in AFib on a 12-lead, get that tracing and the interpreting physician's report into the record. One is enough to satisfy the confirmation requirement.
Holter monitor. A 24 or 48-hour continuous recording. The report's summary page, which lists total AFib burden as a percentage of recorded time and the longest episode duration, is the most useful single document for a paroxysmal AFib claim. Submit the summary page, not just the cardiologist's one-line note.
Event monitor or mobile cardiac telemetry. Worn for 14 to 30 days, and far more likely than a Holter to capture intermittent episodes. Request the full diagnostic report, which lists each detected episode with a date, time, duration, and rhythm strip.
Implantable loop recorder. If you have a Linq, Confirm Rx, or similar device, the interrogation reports contain a complete AFib burden history. These reports are usually stored in the device clinic's system rather than the general chart, so request them by name.
Consumer wearables. A single-lead reading from a smartwatch is suggestive, not confirmatory. It can prompt a provider to order proper monitoring, and the resulting clinical study is what the VA will rely on. Do not build a claim on watch data alone.
For an increase claim, the pairing that moves ratings is simple: rhythm documentation showing the AFib is real and active, plus a dated list of every intervention in the past twelve months.
Building the intervention log
Most 10 percent ratings that should have been 30 percent fail on record assembly, not on the merits. Interventions happen in emergency departments, at community care hospitals, and in outpatient EP labs, and those records do not automatically flow into the VA claims file.
Build a one-page log listing each intervention with the date, the facility, the procedure or drug, and the exact document that proves it. Then obtain those documents yourself and submit them with the claim.
- Cardioversion: the procedure note and the pre- and post-procedure rhythm strips
- ED IV rate control: the ED encounter note plus the medication administration record showing the IV push or drip
- Catheter ablation: the operative report, the pre-procedure ECG, and the discharge summary
- Community care treatment: request records directly from the private facility; do not assume the VA pulled them
If you had two cardioversions, three ED visits with IV diltiazem, and an ablation in the same twelve-month window, that is six interventions and squarely a 30 percent picture, but only if all six documents are in the file when the rater reads it.
Catheter ablation and what happens after
Ablation is a single treatment intervention on the date it is performed. A redo ablation is a second intervention. The three-month post-ablation blanking period, during which recurrent AFib is medically expected and not treated as failure, is a clinical concept and does not carry any special meaning in the rating schedule. Interventions performed during that window still count.
Ablation is also where AFib ratings most often fall. A successful ablation can end the intervention history and, if the veteran also comes off antiarrhythmic medication, remove the basis for even the 10 percent continuous medication tier. Two points worth knowing:
- A rating in effect for five years or more is protected under 38 CFR 3.951 against reduction unless the improvement is shown to be sustained under the ordinary conditions of life. A single good post-ablation echocardiogram is not sufficient.
- Many veterans remain on an anticoagulant indefinitely after ablation because their stroke risk score has not changed. Anticoagulation alone does not support the 10 percent tier, since it is not rhythm control. If the intervention history has ended and rhythm medication has been stopped, the durable claim value usually shifts to secondary conditions rather than to DC 7010 itself.
When AFib rates higher than 30 percent
DC 7010 stops at 30. Higher evaluations for a heart condition come from the General Rating Formula for Diseases of the Heart, which the VA applies when AFib has produced measurable cardiac impairment such as tachycardia-induced cardiomyopathy, reduced ejection fraction, or heart failure.
| Finding | Rating |
|---|
| Workload of 3.0 METs or less producing symptoms, or chronic congestive heart failure, or ejection fraction below 30% | 100% |
| Workload of 3.1 to 5.0 METs producing symptoms, or one or more episodes of congestive heart failure in the past year, or ejection fraction of 30 to 50% | 60% |
| Workload of 5.1 to 7.0 METs producing symptoms, or cardiac hypertrophy or dilatation on echocardiogram, ECG, or X-ray | 30% |
| Workload of 7.1 to 10.0 METs producing symptoms, or continuous medication required | 10% |
The VA assigns one evaluation for one heart disability, so you will not receive DC 7010 and a General Rating Formula evaluation stacked together for the same heart. The rater picks the code and criteria that produce the higher rating. If your echocardiogram shows left atrial enlargement, left ventricular hypertrophy, or a depressed ejection fraction, make sure that report is in the file. Cardiac hypertrophy or dilatation on imaging supports 30 percent on its own, and a reduced ejection fraction can support 60.
If you cannot complete an exercise stress test because of a medical contraindication, the examiner is permitted to provide an estimated METs level based on your reported activity tolerance. Describe specific activities: how far you can walk before you have to stop, whether you can climb a flight of stairs, whether you can carry groceries.
Getting AFib service connected
AFib is rarely diagnosed on active duty, which makes secondary service connection the main path for most veterans. A secondary claim needs three things: a current AFib diagnosis, an existing service-connected condition, and a medical nexus opinion stating it is at least as likely as not that the service-connected condition caused or aggravated the AFib.
Obstructive sleep apnea. The strongest and most widely used pathway. The medical literature on this is unusually solid: repeated nighttime oxygen desaturation, intrathoracic pressure swings, and autonomic surges promote atrial remodeling, and studies have reported roughly a four-fold higher odds of AFib in people with sleep-disordered breathing. Untreated or poorly adherent OSA is also associated with higher AFib recurrence after ablation, which supports aggravation as well as causation. A nexus letter here should cite the sleep study, the AHI, CPAP adherence data, and the temporal relationship between the OSA diagnosis and the AFib onset.
PTSD and other mental health conditions. Chronic sympathetic activation and elevated catecholamines are recognized contributors to arrhythmia risk. This pathway is weaker on its own than OSA, but it is stronger when combined with a documented history of AFib episodes triggered by acute stress.
Hypertension. Long-standing hypertension causes left atrial enlargement, and left atrial enlargement is the structural substrate for AFib. If you are service connected for hypertension and your echocardiogram shows an enlarged left atrium, that finding is the bridge.
Ischemic heart disease from toxic exposure. Ischemic heart disease is presumptive for Agent Orange exposure, and AFib secondary to established ischemic heart disease is a recognized progression. Note that AFib itself is not on any presumptive list, including the PACT Act lists.
Hyperthyroidism and medication side effects. Less common but legitimate, particularly where a service-connected thyroid condition or a medication prescribed for a service-connected condition is documented as the AFib trigger.
Secondary claims that flow from AFib
Once AFib is service connected, it can support additional claims of its own. These are frequently missed.
Stroke and TIA. AFib causes cardioembolic stroke, and a stroke secondary to service-connected AFib is compensable. Brain vessel embolism is rated under DC 8007 at 100 percent for six months from the date of the event, then re-evaluated with a minimum 10 percent for residuals. Residuals are rated separately by function affected: hemiparesis, aphasia, visual field loss, and cognitive impairment each get their own evaluation.
Anticoagulation complications. Gastrointestinal bleeding, anemia from chronic blood loss, and hemorrhagic complications caused by anticoagulants prescribed for service-connected AFib are compensable as secondary conditions.
Heart failure and cardiomyopathy. Poorly rate-controlled AFib can produce tachycardia-induced cardiomyopathy. This is usually captured by re-rating the heart under the General Rating Formula rather than as a separate award.
Pacemaker after AV node ablation. If AV node ablation left you pacemaker-dependent, DC 7009 provides 100 percent for one month following implantation, then evaluation under the General Rating Formula.
Mental health. Anxiety and depression secondary to a chronic cardiac condition are compensable when supported by a diagnosis and a nexus.
2026 compensation amounts
VA compensation rates rose 2.8 percent effective December 1, 2025. Monthly amounts for a veteran with no dependents at the ratings most relevant to AFib claims:
| Rating | Monthly Payment (veteran, no dependents) |
|---|
| 10% | $180.42 |
| 30% | $552.47 |
| 60% | $1,435.02 |
| 100% | $3,938.58 |
Ratings of 30 percent and above add compensation for a dependent spouse, children, or dependent parents. Ratings below 30 percent pay the same regardless of dependents.
Filing or increasing an AFib claim
- Get the ECG or monitor report that confirms the diagnosis and put it in the file yourself rather than relying on the VA to locate it.
- Assemble the twelve-month intervention log with supporting documents for each entry.
- Obtain a nexus letter if you are claiming secondary service connection, and make sure it addresses causation and aggravation separately. An opinion that only addresses causation is a common reason for remand.
- File VA Form 21-526EZ on VA.gov, by mail, or through an accredited Veterans Service Officer. Use Form 21-526EZ for an increase as well.
- Attend the Compensation and Pension exam. Bring your intervention log. Examiners complete a Heart Conditions Disability Benefits Questionnaire, and the intervention count is a field they must fill in.
- If the decision assigns 10 percent when your records show five or more interventions, file a Higher-Level Review. If interventions are missing from the file, file a Supplemental Claim with those records instead, since a Higher-Level Review does not accept new evidence.
Frequently Asked Questions
What is the VA disability rating for atrial fibrillation in 2026?
AFib is rated 10 percent or 30 percent under Diagnostic Code 7010. Thirty percent requires ECG-confirmed AFib with five or more treatment interventions in a year. Ten percent applies with one to four interventions, or with continuous oral medication or vagal maneuvers used to control the rhythm.
Does catheter ablation count toward the 30 percent rating?
Yes. Catheter ablation is explicitly listed in the regulation as a treatment intervention, alongside cardioversion and intravenous pharmacologic adjustment. Each ablation, including a redo procedure, counts as one intervention in the twelve-month count.
Can I get more than 30 percent for AFib?
Not under DC 7010 alone. Higher evaluations come from the General Rating Formula for Diseases of the Heart when AFib has caused measurable cardiac impairment, such as cardiac hypertrophy or dilatation on imaging (30 percent), an ejection fraction of 30 to 50 percent or an episode of congestive heart failure (60 percent), or an ejection fraction below 30 percent (100 percent). Separately ratable conditions such as stroke residuals combine on top under VA math.
Is blood thinner alone enough for a 10 percent rating?
No. Anticoagulants such as warfarin, apixaban, and rivaroxaban prevent stroke but do not control heart rhythm. The 10 percent continuous medication clause refers to medication used to control the arrhythmia itself, such as a beta-blocker, calcium channel blocker, or antiarrhythmic. Anticoagulation matters for secondary claims, not for the DC 7010 tier.
Can I get AFib service connected as secondary to sleep apnea?
Yes, and it is the most common successful pathway. The medical literature links obstructive sleep apnea to substantially higher AFib risk through nighttime oxygen desaturation and autonomic stress. You need a current AFib diagnosis, an existing service-connected OSA rating, and a nexus opinion stating it is at least as likely as not that the OSA caused or aggravated the AFib.
Is atrial fibrillation a presumptive condition under the PACT Act?
No. AFib is not on any VA presumptive list, including the PACT Act burn pit and Agent Orange lists. Ischemic heart disease is presumptive for Agent Orange exposure, so a veteran with presumptive ischemic heart disease may be able to connect AFib secondary to it.
What happens to my rating after a successful ablation?
If the ablation ends your intervention history and you stop taking rhythm-control medication, the VA can propose a reduction at the next scheduled examination. A rating that has been in effect for five years or more cannot be reduced without evidence of sustained improvement under the ordinary conditions of life, and a rating in effect for twenty years or more is protected from reduction below its established level entirely.
Does permanent atrial fibrillation get a higher rating than paroxysmal?
Usually not under the current criteria. Permanent AFib managed with rate-control medication and no further procedures typically rates 10 percent under the continuous medication clause. Persistent AFib requiring repeated cardioversions is more likely to reach 30 percent. If permanent AFib has caused structural heart changes or reduced ejection fraction, the General Rating Formula is the path to a higher evaluation.
