Upcoding

If your visit seemed straightforward but you see a high-level code, the provider may have billed for a more complex service than what was performed. Compare the code level to the time you actually spent with the doctor.

Duplicate charges

Check if this code appears more than once on the same date of service. Unless you had the same procedure performed twice (rare), a duplicate is likely a billing error.

Price check

If you're being charged more than 4,800 for this service, it's significantly above the typical range. Request an itemized bill and compare against the Medicare rate of $266.
