In the ICD-10-PCS Medical and Surgical section, what does the third-character value M represent?

The third-character value 'M' in the ICD-10-PCS Medical and Surgical section signifies "Reattachment." This value indicates procedures involving the reattachment of parts of the body that may have been severed or separated, emphasizing the surgical complexity involved in reconnecting tissues or limbs. It reflects not just the physical act of reattachment but the critical interpretation of restoring anatomical continuity, often following trauma or surgical intervention.

In the context of coding, using the correct third-character value is essential for accurately describing the procedure performed. Each character in the code provides specific information about the nature of the surgical intervention, helping ensure that health records reflect exactly what occurred during treatment. Understanding these values is crucial for coders to communicate effectively and to support billing and reimbursement processes accurately.
