What is the approach for injections in ICD-10-PCS?

In ICD-10-PCS, the approach for injections is classified as "Closed." This is because injections typically involve the use of a needle or cannula to access a site without making a surgical incision, which aligns with the definition of a closed approach. Closed procedures are those where there is no incision made into the skin or a body cavity, and the manipulation occurs externally or via a puncture.

This classification is essential for coding as it helps to accurately represent the nature and complexity of the procedure performed. Understanding the approach allows coders to classify procedures correctly within the ICD-10-PCS system, ensuring proper documentation and billing. Other approaches like open, percutaneous, and endoscopic involve different techniques that do not apply to standard injection practices.
