Solomon Copilot™What is upcoding?
Upcoding is one of the most expensive billing problems a patient can face, and one of the most disputable, because it leaves a paper trail in the codes themselves.
Coding, and miscoding
Every service is billed under a standardized code (CPT or HCPCS) that maps to a price. Upcoding is when a provider bills under a more intensive, higher-paying code than the actual service warranted.
A common example
Emergency visits are billed across acuity levels. A straightforward visit billed at the highest level (CPT 99285) instead of a lower one can multiply the charge, and that gap is exactly what a dispute letter can target.
How to spot it
- Compare the code billed against what actually happened during your visit.
- Check the billed amount against the Medicare benchmark for that code, a large gap is a red flag.
- Watch for the highest-acuity code on a routine visit.
You don't need to memorize the code set. Solomon checks each code on your bill against benchmarks and flags likely upcoding, then drafts the dispute citing the specific code and the gap.
Stop guessing. See your bill, line by line.
Solomon scans every charge against current benchmarks, flags the errors and overcharges, and writes the dispute letter they will answer.
Analyze My Bill →Common questions
Is upcoding always intentional fraud?
Not necessarily, some upcoding is clerical error. Either way, the result is the same overcharge, and either way you can dispute it by pointing to the mismatch between the code and the care.
How do I prove a charge was upcoded?
You point to the gap: the code billed versus the care you received, and the billed amount versus the benchmark for that code. A documented dispute letter puts the burden on the biller to justify it.
