Home › Guides › Does Pet Insurance Cover ACL Surgery?
Updated August 2026Yes — pet insurance covers ACL (CCL) surgery for dogs, as long as the injury isn't pre-existing and happens after any applicable waiting period. A cruciate repair is one of the most common — and most expensive — dog surgeries, typically $3,000–$5,000. With an accident-and-illness plan reimbursing 80–90%, that becomes a few hundred dollars out of pocket.
What is ACL (CCL) surgery in dogs?
What people call the "ACL" in dogs is technically the cranial cruciate ligament (CCL) — the knee ligament equivalent to the human ACL. When it tears (partially or fully), the knee becomes unstable and painful, and most dogs need surgery to walk normally again. The most common repair is a TPLO (tibial-plateau-leveling osteotomy); other options include TTA and lateral suture. It's especially common in Labrador Retrievers, Rottweilers, Newfoundlands, and other large, active breeds.
When ACL surgery IS covered
An accident-and-illness policy covers cruciate surgery when:
- The tear is not pre-existing — no prior diagnosis, symptoms, or lameness in that knee before your coverage (and waiting period) began.
- The orthopedic/cruciate waiting period has passed (see below).
- The procedure is medically necessary, not elective.
Covered costs usually include diagnostics (X-rays, exams), the surgery itself, anesthesia, hospitalization, medication, and follow-up rehab — reimbursed at your plan's rate after the deductible. See the full picture of what surgery pet insurance covers.
When it is NOT covered
- Pre-existing tears. If your dog limped on that knee or was diagnosed before coverage began, the repair is excluded.
- During the waiting period. A cruciate tear that happens before the waiting period ends is generally not covered.
- The "other" knee, sometimes. Because dogs that tear one CCL often tear the other, some insurers treat a second-knee tear as related to the pre-existing first one. This bilateral condition rule varies by provider — it's worth checking before you buy.
The cruciate waiting period — the clause that catches people
This is the most important detail for ACL coverage. Many insurers apply a special waiting period for cruciate-ligament and orthopedic conditions — commonly around 6 months, versus the standard 14-day illness wait. Some providers waive or shorten it if you complete a vet exam within a set window of enrolling. The practical takeaway is simple: enroll while your dog is healthy, well before any knee trouble, so the waiting period is long behind you when you need it.
How much does ACL surgery cost — and what you'd actually pay
| Scenario | Typical vet bill | Your cost with 90% reimbursement* |
|---|---|---|
| Small dog, lateral suture repair | $1,500–$3,000 | ~$150–$300 + deductible |
| Large dog, TPLO (most common) | $3,500–$5,000 | ~$350–$500 + deductible |
| Both knees over time (bilateral) | $6,000–$9,000 | ~$600–$900 + deductible |
*Illustrative, after your deductible and assuming the condition is covered. Actual reimbursement depends on your plan.
