What is upcoding?

• A. Billing for a service at a lower level than provided
• B. Billing for a service without authorization
• C. Billing for a service twice
• D. Billing for a service at a higher level than provided

Answer: (D)

Upcoding is charging for a service at a higher level of complexity or intensity than what was actually performed or documented. In medical coding, every service has a code that reflects how involved the visit or procedure was; selecting a more expensive or comprehensive code than justified misrepresents the work done to obtain greater reimbursement. This practice is considered fraudulent or abusive billing and can trigger audits, repayments, and penalties. A relatable way to think about it is billing a simple office visit as a full, high-detail evaluation or billing a minor procedure as a much more extensive one.

This aligns with the idea of billing for a service at a higher level than provided. The other options describe different issues: undercoding means billing for less than was done, billing without authorization is separate from the coding level issue, and double billing means charging twice for the same service.
