What do the first five digits of a CPT code signify?

The first five digits of a CPT code signify the specific procedure or service performed. CPT, which stands for Current Procedural Terminology, was developed to provide a uniform language for describing medical, surgical, and diagnostic services. Each five-digit code corresponds to a particular procedure, allowing healthcare providers, insurers, and coders to communicate effectively about the medical services rendered.

For example, the number 99213 corresponds to a specific level of established office outpatient visit. This coding system ensures that there is a consistent method for identifying and billing for services, which is crucial for accurate record-keeping, reimbursement, and statistical purposes in healthcare.

Other options mentioned do not accurately capture the purpose of the five-digit code; they pertain to different aspects of healthcare operations and provider-patient interactions rather than the coding of specific services.
