Appeal a French Bulldog BOAS denial

Brachycephalic Obstructive Airway Syndrome (BOAS) is the single most-denied condition for French Bulldogs, Pugs, Bostons and English Bulldogs. Insurers almost always reach for "congenital" or "pre-existing" language. The winning lever is clinical-sign timing vs the policy effective date.

Why insurers deny BOAS

• Congenital exclusion: insurer argues the anatomy was present at birth.
• Pre-existing: any breed predisposition note in early records is treated as a diagnosis.
• Waiting period: claim filed inside the breed-specific waiting window.

The clinical-sign timing argument

A breed predisposition is not a diagnosis. What matters is the first clinical sign — stertor at rest, exercise intolerance, regurgitation, syncope, cyanosis. If the first clinical sign is dated after the policy effective date by the treating vet, the claim is not pre-existing.

Evidence checklist

• Policy declarations page with effective date.
• Vet letter dating the first clinical sign (not the breed note).
• Full SOAP notes from the diagnosing visit.
• Surgical estimate or invoice for staphylectomy / rhinoplasty.
