Heart Monitor denials: what the review data shows
Independent reviewers have decided 44 published cases where an insurer denied Heart Monitor — and they overturned the insurer 25% of the time. A denial for Heart Monitor is a starting position, not a final answer.

Conditions behind heart monitor denials
What insurers denied — and how those fights ended.

What the insurer actually argued
Denials fall into different categories, and they don’t succeed equally — so the reason on your letter changes how you should answer it.
| Reason given | Decisions | Overturned |
|---|---|---|
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 34 | 17.6% |
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 10 | 50% |

What the reviewers wrote
Excerpts from the independent reviewers’ published findings — the actual reasoning, quoted, not summarised.
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for mobile cardiac outpatient telemetry. Mobile cardiac outpatient telemetry (MCOT) has emerged as a standard tool in the evaluation of patients with suspected cardiac arrhythmia. While traditional Holter monitors provide continuous electrocardiogram (ECG) monitoring, this modality is generally only available for 24 to 48 hours. Current MCOT systems with advanced technology permit nearly continuous, automatic, and, with some systems, real-time monitoring. These systems are often smaller and less intrusive to patients, leveraging patch-style devices rather than cumbersome, multi-lead systems.
A 64-year-old male enrollee has requested authorization and coverage for real-time remote heart monitoring for evaluation of the enrollee’s atrial fibrillation. Findings: Two physician reviewers found that the patient has a history of atrial fibrillation and atrial flutter. Per the patient, he has undergone electrical cardioversions previously as well as catheter ablation. He is being monitored for unclear reasons but presumably, given his extensive atrial tachyarrhythmias, for rhythm evaluation. His provider has recommended further monitoring with use of an ambulatory event monitor (also known as a memory loop recorder) with real-time capabilities, also known as auto-triggered memory loop recorders. The Health Plan has denied coverage stating that the requested device is considered investigational in the evaluation and treatment of this patient’s medical condition.
Where the denial was upheld
Worth reading too — these show what an appeal has to overcome.
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for mobile cardiac outpatient telemetry device. Findings: The physician reviewer found that non-real time, or off-line, monitoring devices such as extended 24-hour to 48-hour Holter monitoring, or off-line event monitoring, may detect symptomatic and asymptomatic dysrhythmias that occur frequently. Self-activated non-real time and non-continuous monitoring devices, or event recorders, are effective at recording symptomatic dysrhythmias during less frequent symptoms. In cases of infrequent asymptomatic dysrhythmias that require identification, non-real time, off-line, monitoring devices with auto-triggering capability may be used.
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for 30-day external mobile cardiac telemetry device. Non-real-time or off-line monitoring devices such as extended, 48-hour Holter or off-line event monitoring are sufficient for evaluating and identifying dysrhythmias. Continuous off-line 24 to 48-hour Holter monitoring can effectively identify frequent dysrhythmias. Likewise, self-activated and auto-activated non-real-time monitoring devices, or event recorders, are effective at recording dysrhythmias during less frequent symptoms. In this case, the records do not indicate that the patient cannot effectively manage these standard monitoring devices or that these have been previously obtained to evaluate the patient’s condition.
Figures and quotations on this page come from 42,749 published decisions in the California DMHC Independent Medical Review dataset. These are California outcomes — every state runs an equivalent external review, but the rates here are California’s. Excerpts are quoted verbatim from the public record and describe this treatment generally, not any individual case.
How to use this in your appeal
These are outcomes from California’s external review program — an independent physician panel that binds the insurer. Every state has an equivalent process, and internal appeals succeed even more often. Cite the outcome record for Heart Monitorwhen you appeal: reviewers routinely find that denials like yours didn’t hold up.
