Trupanion's definition of a bilateral condition names elbow dysplasia and then spells out all three of its forms, which is unusually specific for a policy document and tells you how often the claim comes up. Because it presents young, there is a real chance the first lameness happens inside a 30 day orthopedic waiting period. That is the difference between a covered joint and one excluded for life.
What is badly formed elbow joints, in plain terms?
Elbow dysplasia is a group of developmental faults in one joint: a fragmented coronoid process, an ununited anconeal process, or a flap of loose cartilage. Any of them leaves the joint surfaces mismatched, and the mismatch grinds. Large breeds show it young, often as a foreleg lameness that worsens after exercise and eases with rest. Arthritis follows early and permanently, and the dog usually needs management for the rest of its life.
At what age does it usually appear?
Early, usually between four and ten months, and usually in a large-breed puppy that has just started to look grown up. The first sign is a foreleg lameness that is worse after a long walk and better after rest, which owners often put down to overdoing it. Because it lands squarely in the window when a new policy is being arranged, elbow dysplasia is one of the conditions most likely to be recorded during a waiting period rather than after it.
Which clause should you check before you buy?
Check whether the bilateral definition names elbow dysplasia specifically or only refers to joints generally, because the three separate faults grouped under this name are sometimes argued about individually. One insurer here lists all three by their clinical names, which removes the argument. Then check the orthopedic waiting period against your puppy's age: if the dog is under a year, the odds of a first lameness inside a 30 day window are not small, and a lameness recorded in that window converts the joint into a pre-existing condition for life.
Do insurers treat both sides of the body as one condition?

Elbow dysplasia: how long before an insurer will pay for it?
Also called badly formed elbow joints. Each insurer's waiting period and second-side rule below, from its own policy document.
Which insurer covers badly formed elbow joints soonest, and which makes you wait?
Elbow dysplasia falls under the orthopedic class at most US insurers. The table below gives each insurer's waiting period and its rule for the second side of the body, taken from the insurer's own policy document.
| Insurer | Waiting period | Second side of the body | Hereditary and congenital | Where it says so |
|---|---|---|---|---|
| Spot | 14 days | Does not reach this condition This policy does name a second-side rule, but by naming specific conditions rather than a whole class, and this condition is not among them. | Covered | Definitions, Ligament and Knee Conditions, page 2, which names ligament, patella, meniscus and soft tissue disorders of the knee and calls them bilateral and related regardless of cause; Definitions, Bilateral Condition, page 2; Exclusions c and o |
| Lemonade | 30 days 30 days for orthopedic conditions, which this policy defines as including elbow dysplasia, hip dysplasia, intervertebral disc degeneration, patellar luxation and ruptured cranial cruciate ligaments. The second-side rule comes from the definition of a Bilateral Condition rather than from the orthopedic clause: it is a test on the condition, which has to be chronic and affect both sides, and not on the class. | Second side counts as pre-existing | Covered | Waiting periods; Definitions, Orthopedic Conditions, page 14, which names elbow dysplasia, hip dysplasia, intervertebral disc degeneration, patellar luxation and ruptured cranial cruciate ligaments; Definitions, Bilateral Condition, page 14: "a chronic condition that affects both sides of your pet's body, even if clinical signs or symptoms do not present at the same time"; Pre-existing conditions, which excludes bilateral conditions whose signs were present before the start date or before the end of a waiting period |
| Trupanion | 30 days No separate orthopedic waiting period is stated in this specimen; orthopedic illness falls under the general 30 day illness waiting period. | Second side counts as pre-existing | Not stated in the document | Waiting period at 5.b(2), page 3 of 9; bilateral exclusion at 5.c(2), page 3 of 9, which names luxating patella by example; definition of a bilateral condition at 7.c, page 6 of 9, which names elbow dysplasia including fragmented coronoid process, ununited anconeal process and osteochondritis dissecans, cruciate issues, luxating patella, hip dysplasia, cherry eye, entropion/ectropion, panosteitis and cataracts |
| Figo | 180 days | Does not reach this condition This policy does name a second-side rule, but by naming specific conditions rather than a whole class, and this condition is not among them. | Covered | Definitions 44, Waiting Period, page 3 of 13, which sets the orthopedic waiting period for dogs at six months; Definitions 28, Orthopedic; General Conditions 6, page 4 of 13, on the Orthopedic Waiver Form |
The waiting period for badly formed elbow joints is the number that decides whether a claim in the first year is paid at all, and it is the figure insurers vary most quietly. Each row below states the section of the policy it came from.
