The term "diagnostic coding" specifically refers to the assignment of codes for specific diagnoses. This process is integral to health care billing and record-keeping, as it translates a patient's medical condition into a standardized code that can be universally understood within the healthcare system.

Diagnostic coding typically involves using classification systems such as the ICD (International Classification of Diseases), which provide a systematic way to categorize and document diagnoses. This not only aids in billing and reimbursement processes but also plays a critical role in health data management, epidemiology, and research by allowing for the aggregation of health statistics related to specific conditions.

In contrast to other options, coding treatment outcomes, coding of insurance claims, and coding of laboratory results focus on different aspects of healthcare documentation. While these areas are important for complete medical coding, they do not specifically address the identification and coding of diagnoses, which is the primary focus of diagnostic coding.
