Does Pet Insurance Cover ACL (Cruciate) Surgery in Dogs?
Short answer: yes — most accident & illness plans cover ACL (cruciate ligament) surgery, as long as the injury isn’t pre-existing and you’ve cleared the waiting period. The catch is the waiting period: it ranges from 14 days to a full 12 months depending on the insurer. With surgery costing $1,500–$7,000, this is one of the most important things to get right before you enroll.

What counts as ACL surgery in dogs?
In dogs, the “ACL” is really the cranial cruciate ligament (CCL) — the same knee ligament humans call the ACL. When it tears, the knee becomes unstable and painful, and most dogs need surgery to walk normally again. The three common procedures are TPLO, TTA, and lateral suture. They all cost real money, and pet insurance treats them the same way: as an orthopedic claim.
How much does ACL surgery cost without insurance?
This is why people insure their dogs in the first place. Out of pocket, you’re typically looking at:
- Lateral suture: $1,500–$3,000 (smaller dogs)
- TPLO: $3,500–$7,000 (the gold standard for medium/large dogs)
- Both knees: many dogs blow the second ACL within a year or two — double the bill
The waiting period is everything
Every insurer makes you wait before cruciate claims are covered. This stops people from buying a policy the day after their dog starts limping. The waiting period varies a lot:
| Insurer | Cruciate / orthopedic waiting period |
|---|---|
| ASPCA, Pumpkin, Spot | 14 days |
| Trupanion | 30 days |
| Embrace | 6 months (waivable with an orthopedic exam) |
| Lemonade | 6 months |
| Nationwide, Healthy Paws | 12 months |
If your dog is a breed prone to cruciate tears (Labrador, Rottweiler, Newfoundland, Bulldog), a short waiting period is worth more than a few dollars of monthly savings.
When ACL surgery is NOT covered
Insurance won’t pay if any of these apply:
- Pre-existing: your dog already limped, was diagnosed, or showed lameness before you enrolled — even on the other leg, many insurers consider it related.
- Inside the waiting period: the tear happened or showed symptoms before the period ended.
- Accident-only plan: these only cover a tear caused by a specific accident (a fall, a car), not gradual degeneration.
How reimbursement actually works
You almost always pay the vet first, then get reimbursed. You submit the invoice, the insurer applies your deductible and reimbursement rate (usually 70–90%), and pays you back. On a $5,000 TPLO with a $250 deductible and 80% reimbursement, you’d get back about $3,800.

Frequently Asked Questions
Can I get insurance after my dog tears its ACL?
You can still buy a policy, but the existing tear — and often the other knee — will be excluded as pre-existing. Insurance only protects future, unexpected problems. This is why enrolling while your dog is young and healthy matters so much.
Does pet insurance cover the second ACL if the first was pre-existing?
It depends on the insurer. Some treat bilateral cruciate disease as one pre-existing condition and exclude both knees; others may cover the second knee if enough time passes symptom-free. Always ask the insurer in writing before you buy.
Is TPLO covered the same as other ACL surgeries?
Yes. TPLO, TTA, and lateral suture are all covered under accident & illness plans as long as the cruciate condition isn’t pre-existing and the waiting period has passed.
How fast can I get coverage for ACL surgery?
With ASPCA, Pumpkin, or Spot you’re covered for cruciate issues after just 14 days — the fastest in the market. Insurers like Nationwide and Healthy Paws make you wait a full year.
