Final answer:
The ICD-10-PCS code for arthroscopic surgical repair of a rotator cuff tear with repair of the glenohumeral joint in the right shoulder requires identifying the root operation 'Repair'.
Step-by-step explanation:
The correct ICD-10-PCS code for the surgical repair of a right rotator cuff tear with repair of the glenohumeral joint, done arthroscopically, would be constructed based on the specific details of the procedure. The root operation for repairing the right rotator cuff tear is often considered to be 'Repair' because the objective is to restore the torn rotator cuff to its normal anatomical structure.
About the complexity of this process: To specifically find the ICD-10-PCS code, you may use the ICD-10-PCS reference books or the electronic coding tool to navigate through the tables starting from the section identifier for 'Medical and Surgical,' followed by the body system (which would be upper muscles for the rotator cuff), to the root operation 'Repair'.
