Bilateral condition exclusions

How the rule works

If your pet had a cruciate ligament problem in the left knee before coverage began, a plan with a bilateral exclusion will typically also exclude the right knee — even though it was entirely healthy at enrolment.

The reasoning is that a problem on one side is a strong indicator of risk on the other. Whether you find that fair or not, it's what many contracts say.

Where it bites hardest

• Cruciate ligament injuries, which frequently do affect the second knee in time
• Hip dysplasia, typically affecting both hips
• Elbow dysplasia
• Luxating patella
• Ear and eye conditions, in some contracts

Why cruciate cases are the classic

Cruciate ligament rupture in one knee is commonly followed by the other in due course, and each repair is a major expense. An owner who enrols after the first surgery, expecting the second to be covered, is frequently the person who discovers this rule.

If your pet has already had one side treated, ask specifically whether the other side would be covered before assuming it.

What to ask

• Does this plan apply bilateral exclusions?
• Which conditions are treated as bilateral?
• If one side was treated years ago and fully resolved, does the exclusion still apply?
• Does the curable pre-existing condition policy, if any, apply to the untreated side?
• Is there a plan tier or insurer that doesn't apply this?

The takeaway

Enrol before anything happens on either side. Once one side has a history, this rule can remove the coverage you most wanted, and no amount of shopping around fixes it afterwards.
