Mobile Cardiac Outpatient Telemetry denials: what the review data shows
Independent reviewers have decided 15 published cases where an insurer denied Mobile Cardiac Outpatient Telemetry — and they overturned the insurer 20% of the time. A denial for Mobile Cardiac Outpatient Telemetry is a starting position, not a final answer.

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. | 12 | 16.7% |
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 3 | 33.3% |

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.
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for wearable mobile cardiovascular telemetry services. This high-risk patient was hospitalized for sudden onset chest pain, focal unilateral numbness, and palpitations. The selection of appropriate technology for heart rhythm monitoring is based on factors including diagnostic power, risk stratification accuracy, patient acceptance, degree of automaticity, local availability, symptom frequency, overall clinical condition, and probability of life-threatening arrhythmia. In one study that evaluated patients who underwent outpatient electrocardiogram (ECG) monitoring, the authors concluded that diagnostic yield and anti-arrhythmic therapy initiation rates were both significantly higher in patients who underwent mobile cardiac outpatient telemetry (MCOT) compared to event monitors or Holter monitors.
Where the denial was upheld
Worth reading too — these show what an appeal has to overcome.
Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested reimbursement for mobile cardiac outpatient telemetry (MCOT) services. Non-real time (off-line) monitoring devices such as extended (48-hour) Holter monitoring or off-line event monitoring should have been sufficient for the identification of both symptomatic and asymptomatic dysrhythmias. There is a lack of documentation indicating that the patient was not able to effectively manage standard monitoring devices to evaluate the patient’s condition during the time period under review. Current expert consensus guidelines consider patient-activated event recorders and other off-line monitoring devices appropriate initial tests for the evaluation of supraventricular dysrhythmias including atrial fibrillation.

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 Mobile Cardiac Outpatient Telemetrywhen you appeal: reviewers routinely find that denials like yours didn’t hold up.
