Does pet insurance cover luxating patella (kneecap dislocation)?

What luxating patella means for insurance

Insurers usually file luxating patella / patellar luxation under illness or bone-and-joint / inherited, not accident, even when the skip looks sudden. That puts kneecap disease on the illness clock and, at carriers that isolate joint conditions, on a longer bone-and-joint waiting period.

Bills stack: exams and imaging, pain protocols, weight management, and for Grade 3–4 cases, surgery to deepen the groove or reposition soft tissue, then rehab. Wellness add-ons pay routine care on a schedule; they are not a substitute for illness / bone-and-joint coverage when a kneecap needs surgical repair.

A quote can still come back for a dog that already has a Grade note or intermittent skip. That does not mean kneecap care will be paid back.

See problems already in the record for the general rule, ACL / cruciate when the other common knee bill rides alongside, both-sides conditions when one knee may take the other, and bone-and-joint waiting periods when the clock is longer than ordinary illness.

Carrier-by-carrier (public pages)

Facts below come from official public pages fetched or re-checked in September 2026. They are not personalized underwriting.

Label anything operational stale-prone: verify on the quote form and the issued policy.

• Lemonade:
  • Luxating-patella explainer (updated Jun 2026).
  • Lemonade covers bone-and-joint conditions like luxating patellas when not pre-existing, including eligible tests, surgery, and follow-up care; physical therapy is called out as often needing the optional Physical Therapy add-on.
  • Waiting-period guide, luxating patella is named with hip dysplasia as a inherited example that becomes excluded if noted or diagnosed before the wait ends (public framing: 0 days accidents, 14 days illness, 30 days bone-and-joint). pre-existing guide.
  • Medial Luxating Patella (MLP) diagnosed as a puppy stays pre-existing even if surgery is years later; knee / ligament conditions cannot use the 12-consecutive-month “cured” path.
  • Breed predisposition alone is not pre-existing, signs before the wait ends are.
  • Verify on the quote form.
• Embrace:
  • Genetic / breed-specific coverage page names patellar luxation among common genetic disorders Embrace covers when not pre-existing (tests, surgery, rehab on that marketing page).
  • Accident-and-illness help likewise lists Patellar Luxation among breed-specific examples. bone-and-joint waiting-period help article lists Luxating Patella among dog bone-and-joint conditions that, when they occur or show symptoms before the illness wait ends or during the first ~180 days, are excluded for the life of the policy (sometimes reducible with a vet bone-and-joint exam / bone-and-joint Report Card, state-specific).
  • Sample / v6 terms language we mapped also lists Patellar Luxation among the canine bone-and-joint conditions subject to that longer window. both-sides FAQ language for related conditions (examples include cruciate tears): if one side is pre-existing, the other side is not covered.
  • Verify on the quote form.
• Fetch:
  • Pre-existing page lists torn ligament among lifelong examples and applies bone-and-joint bilateral rules, a prior bone-and-joint bilateral condition on one side typically excludes the same condition on the other.
  • Luxating patella is knee / joint disease in that practical bucket once it is on the chart.
  • Fetch markets inherited / born-with / breed-specific coverage when not pre-existing; illness wait of up to 15 days on public coverage pages; no accident wait in the public framing we use.
  • Breed predisposition alone is not pre-existing, signs before signup or during the wait are.
  • Verify on the quote form.
• Pets Best:
  • Inherited / born-with coverage pages say Accident & Illness plans can cover inherited conditions when symptoms are not present before the effective date or during applicable waits.
  • Sample policy booklets we previously mapped treat both-sides conditions as already there if present before the effective date or wait end.
  • Waiting periods are state-specific; a MN sample we previously mapped uses 14 days illness, 3 days injury, and a longer cruciate clock, do not assume patellar luxation shares that exact cruciate number.
  • Confirm how your state’s Pets Best policy clocks kneecap disease.
  • Verify on the quote form.
• Spot:
  • Chronic / pre-existing not covered on Spot’s public pre-existing pages.
  • Spot’s CA insurer disclosure we previously mapped uses a 14-day accident and illness wait on the first policy period; ligament and knee also 14 days on that notice, and that notice treats ligament and knee conditions as bilateral (both sides) and related regardless of cause.
  • Luxating patella is kneecap / joint disease in that family; confirm how your state’s Spot policy clocks it.
  • Spot’s 180-day path for problems that can clear up (examples like broken bones) does not apply to ligament and knee on that CA notice; do not assume patellar luxation can use a “cured” path.
  • Verify.
• Trupanion:
  • US pre-existing FAQ (language we previously mapped; a direct re-fetch was CDN-blocked on some attempts), conditions with signs before the effective date / waits stay excluded; eligibility for a specific condition cannot be determined until a claim is submitted.
  • Marketing often puts inherited bone-and-joint disease in scope when not pre-existing, with Trupanion’s per-condition deductible / uncapped payout structure mattering for lifelong joint pathways.
  • That is marketing framing.
  • It is not a promise every kneecap claim pays.
  • Waiting periods are state-specific.
  • Verify on the quote form.

Skipping, intermittent limp, and Grade notes count as signs

A formal surgical Grade diagnosis is not required for an exclusion. Chart notes about skipping steps, holding up a hind leg, kicking to “reset” the kneecap, intermittent limp, “rule out luxating patella,” MPL / LPL Grade language on a puppy exam, or surgery already done before the applicable wait ended can be enough for carriers to date pre-existing from signs.

Lemonade’s public pre-existing framing is explicit that signs, diagnosis, or treatment before the waiting period ends make a condition pre-existing, and knee / ligament conditions cannot later become “cured” under the 12-month rule.

If the dog is sound today and you are still shopping, especially for Chihuahuas, Pomeranians, Yorkshire Terriers, French bulldogs, toy poodles, and other small or high-risk breeds, do not wait for the first bad skip before you look at illness and bone-and-joint waits. See bone-and-joint waiting periods.

If luxating patella (or a suspicious knee workup) is already in the record, assume that pathway, and often both knees, is carved out, then decide whether a policy still makes sense for unrelated accidents and illnesses.
