Does pet insurance cover polycystic kidney disease (PKD)?
Yes, if no signs were on record before coverage started. Polycystic kidney disease is a hereditary condition, and the cat-insuring plans we review cover hereditary conditions when signs first appear after enrollment and any waiting period. Our breed data rates Persians high risk with PKD as the headline concern, so the entire claim hinges on enrolling before screening or symptoms document it.

Lemonade is the one insurer on this site we can send you to for a live quote. That does not make it the right plan for every pet. As of August 2026, Lemonade Pet is not available in Alaska, Idaho, Kansas, Kentucky, South Dakota, Vermont, West Virginia, or Wyoming.
Some links here are partner links. If you buy through one, the insurer may pay us a fee. It never changes your premium and it never changes a ranking.
Get a quote from LemonadeWhy PKD is an enrollment-timing disease
PKD causes fluid-filled cysts in the kidneys that grow over years before kidney function fails. Insurers cover it under the same hereditary rule that governs HCM in British Shorthairs: covered if signs first manifest after enrollment and after the waiting period, excluded if anything was documented first.
Because ultrasound screening can detect cysts early, a pre-enrollment vet note is the most common way this claim dies. Enroll a healthy kitten before any renal workup lands in the record.
Waiting periods and chronic-care design
Illness waiting periods run 14 days at Lemonade, Embrace, Spot, Figo and Pets Best, 15 days at Healthy Paws in most states, up to 15 days at Fetch, and 30 days at Trupanion. Official Lemonade waits are 0 days for accidents nationwide, 14 days for illness, and 30 days for orthopedic conditions, with no separate 6-month cruciate wait.
PKD is chronic, so no curable-condition reinstatement path ever applies. For lifelong claims, Trupanion unlimited payout with its deductible paid once per diagnosed condition for the pet life is the documented design fit. Annual-deductible plans reset that cost each year but often price lower month to month. Illustrative Persian premiums start near $34/mo in our catalog, which is an estimate rather than a quote.
