Which coding system is primarily used for hospital inpatient services?

• A. CPT
• B. ICD-10-CM
• C. HCPCS
• D. DSM-5

Answer: (B)

The coding system primarily used for hospital inpatient services is ICD-10-CM (International Classification of Diseases, Tenth Revision, Clinical Modification). This system provides a standardized way to report diagnoses and is essential for hospital inpatient settings because it helps in documenting the severity and complexity of patient conditions. ICD-10-CM codes are critical for determining the medical necessity of inpatient admissions, influencing reimbursement rates, and facilitating statistical data collection for public health and research purposes. Each code corresponds to a specific diagnosis, allowing healthcare providers and payers to understand the patient's health status and the level of care provided. In contrast, CPT (Current Procedural Terminology) is primarily used for reporting outpatient services and procedures, HCPCS (Healthcare Common Procedure Coding System) includes codes for supplies, equipment, and some services that are not covered by CPT, and DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) is used for classifying and diagnosing mental disorders, thus not relevant for coding hospital inpatient services.
