Why was my service not covered?
"Not covered" and "denied" aren't always the same thing.
One means your plan doesn't include this type of service at all. The other means a covered service's claim ran into a problem. They call for very different next steps.
Show me the difference ↓Excluded service vs. denied claim
Both can look similar on paper — a bill you weren't expecting — but they come from very different places.
Your plan's benefit design doesn't include this category of service at all — for anyone on the plan, regardless of circumstances.
- Generally listed in your plan documents as an exclusion
- Not usually about your specific situation
- Harder to appeal — though not always impossible
The service is generally included in your plan's benefits, but this specific claim hit a snag during processing.
- Reasons include coding errors, missing information, network status
- Directly about this specific claim
- Generally appealable, often successfully

What plans typically exclude
This varies significantly by plan — some plans do cover certain items on this list under specific circumstances.
Cosmetic procedures
Generally excluded unless medically necessary (e.g., reconstructive after injury).
Experimental or investigational treatment
Often excluded until a treatment meets a plan's evidence threshold.
Some alternative or complementary medicine
Coverage for acupuncture, chiropractic, etc. varies widely by plan.
Certain elective procedures
Some plans exclude specific elective surgeries, like some weight-loss procedures.
Fertility treatments
Coverage ranges from none to comprehensive, depending on the plan.
Care received outside the country
Often limited to emergencies only, depending on the plan.
What you can still do
Request a medical necessity exception
Some plans allow exceptions when a provider documents a compelling medical reason.
Ask about a covered alternative
An equivalent, covered treatment or approach may exist for your situation.
Ask the provider about financial assistance
Many providers offer payment plans or assistance programs for excluded services.
Double-check the categorization
If you believe the service was miscategorized as excluded rather than covered, that's worth appealing.
In Canada? "Not covered" usually means outside your provincial plan's scope.

Outside your provincial plan's scope
Prescription drugs, dental, and vision generally aren't part of the public plan at all — this isn't a denial, it's just a different layer of coverage. See how the two layers work →
Excluded even from public coverage
Some services — like most cosmetic procedures — are typically excluded from provincial coverage entirely, similar to U.S. plan exclusions.
Don't assume — confirm
Your provincial health ministry's schedule of benefits is the authoritative source for what's included in public coverage.
Common questions about non-covered services
Can an excluded service ever become covered?+
Sometimes — through a documented medical necessity exception, or if your plan changes at renewal. It's worth asking rather than assuming the answer is always no.
Where do I find my plan's exclusion list?+
Your Summary of Benefits and Coverage or full plan document typically lists exclusions — your insurer's member services line can also confirm a specific service.
Is it worth appealing an excluded service?+
It can be, especially if you believe it was miscategorized or if a strong medical necessity argument applies — but expectations should be realistic, since plan design exclusions are harder to overturn than processing errors.
Why did my provider say it would be covered, but my insurer said no?+
Providers aren't always aware of every plan's specific exclusions — your insurer's benefits determination is generally the authoritative answer for your plan.
Know which situation you're in.
That single distinction determines whether you're appealing, exploring alternatives, or looking at financial assistance.
