Which third-character value indicates the root operation of restriction in ICD-10-PCS?

The third-character value that indicates the root operation of restriction in ICD-10-PCS is represented by the letter V. In the context of the ICD-10-PCS coding system, each root operation has a designated character that helps to define the specific action taken in a medical procedure.

Restriction specifically refers to procedures that limit the function of a body part without completely removing or occluding it. For example, this could involve procedures designed to restrict movement in a joint or a narrowing of a passage within the body.

Understanding the coding conventions is crucial for accurate medical documentation and billing. Each root operation's assigned character allows coders to categorize and encode the procedure accurately, ensuring consistency and clarity in health records and claims processing.
