Answer to #1 – 0PSM0ZZ: Reposition right carpal
To locate: PCS Index > Reposition > Bone > Carpal > Right > 0PSM > go to table 0PS and then go across the row to assign the remaining characters: Reposition right carpal, open approach
Reposition, a new term in PCS, replaces reduction. Repair of a displaced fracture is the root operation of Reposition. The pisiform bone is one of the carpal bones. No device was inserted to hold the bone in its correct anatomical position and there no qualifier is appropriate.
Open Approach: Procedures performed directly on the skin or mucous membrane and procedures performed indirectly by the application of external force through the skin or mucous membrane.
Answer to #2 – 0RRK00Z: Replacement of left shoulder joint with reverse ball and socket synthetic substitute, open approach
To Locate: PCS Index > Replacement > Joint > Shoulder > Left > 0RRK > locate table 0RRK and go across the row to assign the remaining characters: Replacement of left shoulder joint with reverse ball and socket synthetic substitute, open approach
Replacement is putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.
Reverse Prosthesis: The left shoulder joint is replaced with a reverse prosthesis (ball on glenoid and socket on humerus).
The synthetic substitute, the “glue” that holds the alignment in place is metal on polyethylene. However, for coding purposes you need to code the device to a synthetic substitute, but the material utilized for the device is not incorporated in this as well as most fracture repair codes using some type of cement or glue.
The removal of the native shoulder joint is included in the replacement procedure and is not coded separately.
Answer to #3 – 0R9W00Z: Drainage of right finger phalangeal joint with drainage device, open approach
To Locate: PCS Index > Drainage > Joint > Finger Phalangeal > Right > 0R9W > locate table 0R9 and then go across the row to assign the remaining characters:
Guideline B6.1a/Drainage Device: Drainage is defined as “Taking or letting out fluid and/or gases from a body part. A separate procedure to insert a drainage device is coded to the root operation, Drainage, with the device value of 0 for Drainage Device. Per PCS coding guidelines, devices that remain in place after the procedure/operation is completed, are to be coded.
