Cruciate Ligament Injury: Why Some Pet Insurance Waiting Periods Run 6 Months
Cruciate ligament injuries carry 6-month waiting periods at several insurers because they are expensive claims that often stem from slow degeneration predating the policy — an easy target for adverse selection. Lemonade (6 months for cruciate specifically), Pets Best and Figo (both waivable with a timely vet exam) and Embrace (cut to 14 days with an orthopedic exam) impose the long hold; Spot applies only its standard 14-day wait but links both knees, so a prior injury on one excludes the other; Trupanion uses its flat 30-day illness wait.

- Several insurers impose a 6-month waiting period specifically on cruciate ligament events — Lemonade (30 days for orthopedic conditions generally, 6 months for cruciate), Pets Best and Figo (6 months, both waivable with a qualifying vet exam) and Embrace (6 months covering cruciate, IVDD and hip dysplasia, cut to 14 days with an exam).
- The reason is adverse selection: cruciate ruptures often involve slow degeneration, so dogs already limping get enrolled and claim within weeks unless carriers add a longer hold.
- Spot has no separate orthopedic or cruciate wait — its standard 14-day illness period applies — but treats both knees as linked, so a prior injury on one side excludes the other.
- Trupanion has no separate orthopedic track either; its flat 5-day accident / 30-day illness waits govern cruciate claims.
- Healthy Paws runs 15 days generally but links knees bilaterally too — hurt one cruciate before enrollment and the other knee is excluded as well.
The Direct Answer
Insurers impose 6-month waiting periods on cruciate ligament injuries because these are among the most expensive, most predictable claims in pet insurance — and among the easiest to game. A cranial cruciate rupture frequently follows months of gradual degeneration rather than a single dramatic twist. That means a dog already intermittently limping can be enrolled on Monday and scheduled for a $3,000-plus repair within the standard illness window, with the degeneration predating the policy. The extended hold exists to push that scenario out of coverage.
The specifics across our catalog: Lemonade applies 30 days to orthopedic conditions generally but 6 months for cruciate events specifically. Pets Best imposes 6 months on cruciate ligament events unless a participating veterinarian certifies the pet (exam up to 3 days before or 7 days after the effective date, form back within 30 days of the exam). Figo runs 6 months on orthopedic conditions, waivable with a vet exam completed and submitted within the enrollment window. Embrace applies 6 months to cruciate injuries, IVDD and hip dysplasia together.
How to Beat or Avoid the Long Wait
Three insurers make the 6-month hold avoidable. Embrace cuts it to 14 days if your vet performs an orthopedic exam and submits it within your first two weeks of coverage — arguably the best waiver in our catalog because it covers cruciate, IVDD and hip dysplasia in one exam. Pets Best waives via a participating vet certification inside its enrollment window. Figo waives with an exam submitted during enrollment. If you are enrolling a healthy dog, doing this paperwork in week one converts a half-year exposure into two weeks.
Two carriers skip the long wait entirely. Spot applies no separate orthopedic or cruciate period — the standard 14-day illness wait governs everything. Trupanion likewise has no special orthopedic track; its 5-day accident and 30-day illness periods apply. But read the linked-exclusion fine print before celebrating: Spot treats both knees as one risk, so a prior cruciate injury on either side excludes the opposite knee too, even though the initial wait is shorter than competitors'. Healthy Paws links knees the same way on top of its general 15-day wait.
Why Cruciate Claims Worry Insurers So Much
Look at breed data and the carrier caution makes sense. Our Labrador entry — moderate risk tier, roughly $46/mo illustrative starting premium — lists cruciate tears first among its defining risks, alongside hip and elbow dysplasia. Large, athletic breeds stress the knee joint constantly, and partial tears that respond to rest can progress to full ruptures months later, blurring exactly when the condition began. From an underwriting desk, that ambiguity is expensive: a claim filed at day 40 may trace to degeneration visible at day minus-60.
The bilateral problem compounds it. When one cruciate goes, the opposite knee carries extra load and fails at elevated rates — which is why Healthy Paws' pre-existing wording explicitly extends an earlier cruciate injury to the other knee, and Spot does the same. For owners, the practical consequence is stark: the knee you enroll matters. A policy bought while both knees are clean covers whichever fails; a policy bought after one failure may leave you self-funding both.
What This Means for Your Enrollment Timing
Enroll before any limp appears — that remains the entire strategy. Once a vet note mentions knee sensitivity, strain or intermittent lameness, most carriers will classify cruciate issues as pre-existing regardless of which knee eventually ruptures, and Lemonade additionally bars knee/ligament conditions from its curable pre-existing pathway permanently. The 14-day and waiver windows reward acting fast: book the orthopedic exam when you buy the policy, not after something goes wrong.
Match the mechanism to your situation honestly. Puppy or young large-breed owner with clean records: Embrace's exam waiver or Spot's short standard wait give fastest protection, while Trupanion's flat structure avoids orthopedic complexity altogether at higher cost (about $62/mo starting). Dog already showing knee signs: no insurer here will cover that trajectory, so weigh whether a policy for everything else still justifies the premium — for many households it does, but go in clear-eyed about what is excluded.
