What is the first body system detailed for medical procedures in the CPT manual?

The Integumentary System is indeed the first body system discussed in the CPT (Current Procedural Terminology) manual. This system encompasses the skin and its associated structures, such as hair, nails, and glands. It plays a crucial role in various medical procedures, including those related to surgery, dermatology, and other medical treatments that involve skin and soft tissue.

By beginning with the Integumentary System, the CPT manual sets the stage for coding procedures that are commonly performed and understood within the context of medical practice, considering that many procedures often start with assessments and treatments concerning the skin. This ordering is logical from a procedural standpoint, as the integumentary procedures frequently set the foundation for more complex interventions that might involve deeper body systems. Understanding the nuances within this chapter helps practitioners accurately document and bill for a wide array of procedures related to skin, which is vital for both clinical practice and administrative purposes.
