I27.20 — Pulmonary Hypertension
Denied68M · investigation — Echocardiography
Insurer Rationale
ECG and chest X-ray have not shown acute structural abnormality. Echocardiography can be deferred to routine outpatient review.
Clinical Contradiction
Insurer states
“Echocardiography is not indicated given stable clinical presentation”
Clinical evidence shows
New murmur with exertional dyspnoea requires echocardiography to differentiate valvular from pulmonary causes
Patient risk
Undiagnosed severe aortic stenosis carries risk of sudden cardiac death
Reasoning Chain
Breathlessness, chest pain, syncope, and oedema are shared between pulmonary hypertension and aortic valve disease. The discriminator is valve-focused structural assessment, and echocardiography is the graph-linked investigation that resolves that uncertainty. Deferring it risks missing severe valve disease at a decompensating boundary.
Reasoning Chain
Findings
Breathlessness, Exertional chest pain, Near-syncope, Ankle oedema, Ejection systolic murmur
Differential
Pulmonary Hypertension (working diagnosis) vs Aortic Valve Disease (not excluded)
Shared findings
Blackouts/faints, Breathlessness, Chest pain, Peripheral oedema
Discriminating investigation — DENIED
Echocardiography
Directly visualises valve pathology, gradients, and right-heart strain to separate the two pathways
Verdict
Denial is clinically unsafe. Routine outpatient deferral leaves a structurally actionable cause of exertional syncope unresolved.
Clinical Evidence
ESC/EACTS Guidelines for the Management of Valvular Heart Disease (2021)
Diagnostic evaluation
Echocardiography is first-line when symptoms raise concern for haemodynamically significant valve disease.
ESC/ERS Guidelines for Pulmonary Hypertension (2022)
Initial diagnostic strategy
Echocardiography is the essential gatekeeping test when pulmonary hypertension is in the differential.
