Which coding system is used to classify diseases and conditions for health statistics and billing purposes?

• A. CPT codes
• B. HIPAA Privacy Rule
• C. OSHA Standards
• D. ICD-10-CM codes

Answer: (D)

Understanding how illnesses are categorized for statistics and billing is about ICD-10-CM. This coding system provides codes for diagnoses and health conditions, enabling consistent reporting of health statistics and accurate reimbursement. Clinicians document the diagnosis, and trained coders translate the medical record into ICD-10-CM codes to be used in claims and health data.

This is different from CPT codes, which describe procedures and services performed rather than diagnoses. The HIPAA Privacy Rule focuses on protecting patient information, not on coding diseases, and OSHA standards regulate workplace safety rather than medical classification.
