What is ICD-10 coding used for, according to the material?

• A. Online training course on how diagnoses should be made.
• B. Used for billing purposes by insurance companies.
• C. A system to track patient satisfaction.
• D. A method for calculating physician salaries.

Answer: (B)

ICD-10 coding is the standardized way to classify and code diagnoses and medical conditions, with the main purpose being billing and reimbursement. Insurers rely on these codes to determine payment for services, process claims, and track what care was provided. The codes also support data collection for epidemiology, quality measurement, and health system planning. It isn’t a training course for how diagnoses are made, it doesn’t track patient satisfaction, and it isn’t used to calculate physician salaries.
