Upcoding

Also called: Overcoding

In plain English

A billing practice (which can be fraud) where a provider bills for a more expensive service than what was actually performed. This results in higher charges to you and your insurance.

Real-world example

You have a routine 15-minute follow-up visit (should be CPT 99213, ~$92 Medicare rate) but get billed as a complex visit (CPT 99215, ~$175 Medicare rate). The difference might cost you an extra $100+ in coinsurance.

Why this matters for your bill

Upcoding is one of the most common medical billing errors/abuses. It's hard to catch unless you know what the codes mean. The biggest red flag: your ER visit being coded at Level 5 (99285) when you walked in with something minor.
