What does the approach 'open' mean in the context of ICD-10-PCS?

In the context of ICD-10-PCS, the term 'open' signifies that the procedure involves accessing a body part through an incision made in the skin or a body cavity. This approach provides direct visualization and access to the area being treated, which is critical for many surgical procedures that require precision and thoroughness. Open procedures are typically more invasive than minimally invasive techniques, which are designed to minimize tissue damage and recovery time.

This definition aligns with the coding guidelines where an open approach is characterized distinctly to differentiate it from other methods, such as minimally invasive or endoscopic approaches. Proper understanding of this term is essential for accurate coding and reporting of procedures in the medical records.
