CCS ICD-10-PCS Inpatient Procedure Coding 2

Question 1

In ICD-10-PCS, what distinguishes the root operation 'Fusion' from 'Repair'?

Accepted Answer

Fusion joins body parts rendering them immobile; Repair restores normal structure

Answer

Fusion (value G) joins portions of a body part to render them immovable (e.g., spinal fusion). Repair (value Q) restores a body part to its normal anatomic structure without fusing it.

Question 2

A patient undergoes a right total knee replacement. Which ICD-10-PCS root operation is used?

Accepted Answer

Replacement

Answer

Total joint arthroplasty uses root operation Replacement (value R) - putting in or on biological or synthetic material that physically takes the place of a body part.

Question 3

How does ICD-10-PCS handle bilateral procedures?

Accepted Answer

Separate codes are assigned for each side, as body part values are side-specific

Answer

ICD-10-PCS assigns side-specific body part values (right, left) or a bilateral value where it exists. When bilateral values are available, one code captures both. When not available, two codes are required.

Question 4

In ICD-10-PCS, what is the approach value for a procedure performed entirely through a natural body orifice using an endoscope (e.g., colonoscopy)?

Accepted Answer

8 - Via Natural or Artificial Opening Endoscopic

Answer

Approach 8 (Via Natural or Artificial Opening Endoscopic) is used for endoscopic procedures performed through a natural orifice using an endoscope - such as colonoscopy, upper GI endoscopy, or cystoscopy.

Question 5

A patient has a pacemaker generator implanted in the subcutaneous tissue of the chest wall along with insertion of pacing leads into the right ventricle. How many ICD-10-PCS codes are needed?

Accepted Answer

Two codes - one for the generator insertion and one for the lead insertion

Answer

ICD-10-PCS guidelines require separate codes for pacemaker generator insertion (into subcutaneous tissue) and lead insertion (into the cardiac chamber), as they involve different body parts.
