"Same or similar": why a claim can be denied
A common cause of surprise denials — and how we prevent it.
Key takeaways
- Medicare won't pay for a duplicate of equipment you already have within its useful life.
- It's a common surprise-denial cause — even when you switch suppliers.
- We check your history first and document any change in your condition.
What “same or similar” means
Medicare generally won't pay for a new item if you already have one that serves the same purpose and it's still within its useful lifetime (often about 5 years). This is the “same or similar” rule.
Why it causes denials
If you — or a previous supplier — already billed Medicare for, say, a walker or a wheelchair, a second one may be denied even if your situation changed. It can also happen if you switched suppliers.
How we prevent surprises
Before we deliver, we check your equipment history for same-or-similar conflicts. If there's a flag, we document the change in your condition, pursue an exception or upgrade where appropriate, or lay out a clear private-pay option — so you're never blindsided by a denial.
