Does Pet Insurance Cover Hereditary and Congenital Conditions? Hip Dysplasia, Cherry Eye, and Liver Shunts Compared
Cavaliers are prone to mitral valve disease before age five. Frenchies are born with narrowed airways. Shepherds carry a genetic predisposition to hip dysplasia. None of that is caught later -- it's baked in from birth. So when a claim comes in, does insurance pay, or does it treat a hereditary trait like a pre-existing illness?
Hereditary vs. Congenital
Congenital means present at birth, inherited or not -- a liver shunt is the classic example. Hereditary means genetically passed down, like hip dysplasia. The NAIC's 2022 Model Act defines both and requires disclosure of exclusions, but doesn't force anyone to cover them.
The Short Answer: Usually Covered, With a Catch
Trupanion, Healthy Paws, and ASPCA Pet Health Insurance all say these conditions are covered on standard plans, provided no symptoms showed before the effective date. Coverage starts after a wait -- days for injuries, 14-30 for illness, though ASPCA runs a flat 6-month wait on these claims. Check that before assuming a typical monthly premium buys blanket protection.
Where It Blurs Into "Pre-Existing"
A hereditary condition doesn't announce itself at birth -- a dog can carry hip dysplasia genes for years before a limp shows. Symptoms noted before enrollment get filed as pre-existing, a permanent exclusion, not a temporary wait; our waiting-period breakdown covers how insurers read vet records. Some also apply a bilateral exclusion: diagnose one knee, the other gets excluded too.
What These Conditions Cost in Cash
Hip replacement runs $3,500-$7,000 per hip, an FHO $1,200-$2,500 -- see our hip dysplasia cost comparison. Patellar luxation repair is $1,500-$4,500 per knee, cherry eye surgery $300-$2,500. Liver shunt surgery is the outlier: $2,000-$7,500 extrahepatic, up to $12,000 for an intrahepatic coiling procedure.
Breed Riders and Age Cutoffs
Healthy Paws won't cover hip dysplasia if a dog enrolled at six or older, plus a 12-month wait regardless of age. ASPCA covers it at any age but applies its own 6-month wait instead. Some carriers attach riders capping airway surgery for Frenchies -- read the policy, not a comparison chart.
State Rules Are Catching Up
Pet insurance has been lightly regulated compared to auto or health coverage. The NAIC model act requires plain-language disclosure of these exclusions, plus agent training minimums. States adopt it individually, so disclosures still vary. Ask for the sample policy first.
Bottom Line
Insuring a breed with known hereditary risk means enrolling before any symptom hits a vet record; that separates "covered" from "excluded." Check the hereditary/congenital wait, and ask if the breed carries a rider.
