Which code would you use for a regular check-up appointment?

A regular check-up appointment is typically coded using a CPT (Current Procedural Terminology) code because this category specifically encompasses the codes for various medical procedures and services provided by healthcare professionals. These codes are essential for billing purposes, as they represent the services rendered during the appointment, which in this case involves a preventive health examination or evaluation.

In the context of a check-up, a CPT code for a preventive visit would be used to describe the specific services provided during that encounter. This allows healthcare providers to receive appropriate reimbursement from health insurance companies for the services rendered.

While ICD codes are used to describe diagnoses, modifier codes are used to indicate that a service has been altered in some way, and HCPCS codes cover items, supplies, and certain procedures not included in the CPT coding system, none of these codes are appropriate for describing the standard procedures performed during a routine check-up.
