Hello Everyone,

I'm not sure which code better fits this situation. Normally I'd go for a regular debridement code since that would include the irrigation, but the doctor wants to code 27301, but I'm not sure it includes the debridement? And in that case, would 27310 be worthwhile to look at? Let me know what you think. Thank you in advance! :)

Pathology came back with no growth aerobic or anaerobic.

Here is the report:

POSTOPERATIVE DIAGNOSIS:
Right knee infection.

OPERATION PERFORMED:
Irrigation and debridement of right knee.

Findings:
Some necrotic tissue, purulent tissue, two FiberWire sutures were removed.

DESCRIPTION OF PROCEDURE:
The patient was brought to the operating room. General anesthesia was induced. He was positioned in the supine position. Care was taken to ensure all areas were well-padded. The right lower extremity was prepped and draped using standard technique. The previous incision was used 3 cm proximal and 2 cm distal. I did ellipse around the draining sinus. We came to the patella and made a medial soft tissue dissection following a sinus tract and this was carried back to a FiberWire suture from the medial retinacular repair. Two of these removed. There was no frank pus but some necrotic tissue. We did take some cultures from around this area, debriding necrotic tissue. I did not see any evidence of necrotic bone. There was no effusion in the knee. We did not enter the joint capsule. Once we had removed the sutures and adequately debrided the area, we thoroughly irrigated and then loosely closed the incision with the exception of a small area where we had debrided the draining sinus and this was packed with a wet to dray dressing. Sterile dressing was applied. The patient was awakened and taken to the recovery room and doing well.
 
The debridement codes in the Integumentary system are used for debriding open wounds. This is not an open wound. If the surgeon has to make an incision to get to the site, any code in the 110XX section will not be used.
 
I think 27310 is not appropriate due being the joint capsule was not entered. How far down was the dissection? (medial patella soft tissue) to debride the necrotic tissue? Check your coder desk reference to arrive to a correct cpt code.
 
I agree. The incision went past the sub-Q and stopped at the retinacula tissue, which is probably the tissue that was debrided, but the documentation does not state the specific tissue that was debrided. Since there is basically no medical necessity documented for the removal of the sutures I think your best code is 27301.
