What CPT, HCPCS and revenue codes mean on a bill
The short codes next to each charge, explained.
Most itemized bills list a code next to each charge. These codes are how providers tell insurers what was done.
CPT codes are five-character codes for procedures and services, like an office visit or a lab test. HCPCS codes cover other items such as supplies, equipment and some drugs. Hospital bills also often show revenue codes — usually four digits — that say which department the charge came from, like pharmacy or emergency room.
You don't need to memorise codes. They are useful because they let you ask a precise question: "What is code X on this date, and why does it appear twice?"
A word of caution
A code that looks unfamiliar is not a sign that anything is wrong. Only the provider and your insurer can confirm what a code covered on your visit.
