What is the significance of ICD-10-CM?

• A. It is used for classifying hospital departments.
• B. It is the standard for coding medical diagnoses and procedures for insurance claims.
• C. It is a budgeting tool.
• D. It is a clinical trial protocol standard.

Answer: (B)

ICD-10-CM provides a standardized language for capturing patient diagnoses in health records and billing. The expanded codes offer much greater specificity, allowing coders to detail exact conditions, laterality, severity, and related factors. This precision improves accuracy in claims processing, supports appropriate reimbursement, and enhances data quality for research, quality reporting, and public health tracking. In practice, it’s the primary reference hospitals and clinicians use when coding diagnoses for insurance claims, while separate coding systems handle inpatient procedures.
