Curable Pre-Existing Conditions: The 180-Day Rule

Updated May 20266 min readCarrier policy schedules

The most-misunderstood term in pet insurance. A curable pre-existing condition is the one carve-out that lets a previously-excluded condition come back into coverage — but only for specific kinds of conditions, only after a strict symptom-free period, and only at carriers that publish the rule. This page covers which conditions qualify, the 180-day mechanics, and a carrier-by-carrier comparison.

The 30-second answer

Acute conditions that fully resolve (ear infection, UTI, kennel cough) can be covered again after typically 180 symptom-free days. Chronic conditions where the underlying cause persists (allergies, arthritis, diabetes) are excluded permanently — there's no curable carve-out for them.

How the 180-day rule actually works

Three conditions must all be true for a pre-existing exclusion to convert to coverable:

  1. The condition must be on the carrier's curable list. This is published in the policy schedule. Anything chronic or progressive (cancer, diabetes, kidney disease, allergies) is automatically off the list.
  2. 180 consecutive symptom-free days. No clinical signs in vet records, no medication, no follow-up visits referencing the condition. Even a single recheck note like "ear looks better but recommend continued cleaning" can reset the clock.
  3. The recurrence must be documented as a new acute event, not as a continuation. The vet's diagnosis wording matters: "new acute otitis externa" helps; "chronic recurring otitis" doesn't.

The curable list (typical, by category)

Usually CURABLE

  • Ear infections (acute)
  • Urinary tract infections
  • Kennel cough / acute respiratory
  • Acute vomiting / diarrhea
  • Mild gastroenteritis
  • Simple bacterial skin infections
  • Conjunctivitis (acute)
  • Minor lacerations / abrasions
  • Sprains and strains

Almost never curable

  • Allergies (atopic / food)
  • Arthritis
  • Diabetes mellitus
  • Heart disease
  • Kidney disease
  • Hyper-/hypothyroidism
  • IBD / chronic GI
  • Epilepsy
  • Any cancer
  • Cruciate ligament disease (typically bilateral-excluded)

The curable list is set by each carrier and varies year to year. Always confirm against the policy schedule attached to your declarations page.

Carrier policies update annually; verify the current schedule when quoting. Healthy Paws' and Trupanion's lifetime exclusion is offset by other plan features (no annual limit on Healthy Paws, lifetime per-condition deductible on Trupanion).

Florida-specific note

Florida's 2023 adoption of NAIC §633 requires carriers to publish their curable-condition list in plain language on the policy schedule, with the symptom-free window stated explicitly. Wrisor verifies the carve-out language for every Florida customer at quote time — if a condition's curable status is ambiguous, it gets resolved before policy purchase, not after a denial.

Documentation that gets the carve-out approved

Three records that turn a curable claim from "maybe" to "yes":

  1. The original resolution note. The vet visit where the original condition was declared resolved — "ears clean, no inflammation, infection cleared." This anchors day zero of the 180-day window.
  2. An interim wellness exam in the symptom-free window. Even a routine annual exam with the chart noting "no symptoms relevant to prior condition" — affirmative evidence beats absence of records.
  3. The new diagnosis worded as acute. When the recurrence happens, ask the vet to use "new acute" language in the chart, not "recurring" or "chronic." The wording is reviewable by the insurer when the claim is filed.

Frequently Asked Questions

A curable pre-existing condition is one that is fully resolved with no clinical signs for a specified period — typically 180 consecutive days, though some carriers use 12 months. After the symptom-free window, if the condition recurs, it can be treated as a new condition for coverage purposes. The list of conditions classified as "curable" varies by carrier and is usually published in the policy schedule.

Embrace, ASPCA Pet Insurance, MetLife, Pets Best, and modern carriers all maintain a curable carve-out, typically with a 180-day symptom-free requirement. Healthy Paws and Trupanion treat all pre-existing conditions as permanently excluded with no curable distinction. Always verify in writing — the carve-out is contract language and varies year to year.

The industry standard is 180 days (about 6 months) of no clinical signs, no treatment, and no medication for the specific condition. Some carriers extend this to 12 months for orthopedic and dermatological conditions. The clock starts on the last day of treatment or symptoms, whichever is later — and can be reset by even a single follow-up visit if the vet documents anything related.

Generally curable: ear infections (acute, not chronic otitis), urinary tract infections, kennel cough, vomiting episodes, mild gastroenteritis, simple skin infections, eye infections, and minor lacerations. Generally NOT curable: allergies, arthritis, diabetes, heart disease, kidney disease, hyperthyroidism, hypothyroidism, IBD, epilepsy, and any cancer. The non-curable list is essentially "any chronic condition where the underlying cause persists."

Probably yes, on most carriers — assuming (1) the original infection was fully resolved, (2) there have been no symptoms, treatments, or vet notes about ears for 180+ days, and (3) the new infection is in a different location or is documented as a new acute event rather than a chronic recurring condition. Chronic otitis (recurring 3+ times) is usually classified as a single ongoing condition, not separate curable events.

No. The curable rule applies to the condition as a whole, not to anatomical sides. An ear infection in the left ear does not reset the clock for the right ear; both are "ear infections" under the curable rule. Bilateral exclusions apply separately and can stack with the curable rule unfavorably — see the bilateral-exclusion glossary entry.

Keep all vet records and request a copy of any visit summaries. The most useful documentation is a routine wellness exam during the symptom-free window with explicit notes like "ears clean, no inflammation" or "no GI signs reported." Insurers prefer affirmative evidence of resolution over absence of records. If you switch vets during this window, transfer all records — gaps in chart history can be interpreted unfavorably.
