Wiki Amputation revision coding

[Bethvoce]

Is the removal of nonviable tissue from the below knee amputation site for necrotic tissue considered a "Revision of right below knee amputation" codeable as 27884 or just a "Secondary closure of a surgical wound or dehiscence, extensive or complicated" codeable as 13160? The Physicians description in the Operative Note is as follows: "A 15 blade was used to cut the nonviable tissue from the suture line. Was dissected until healthy bleeding tissue was identified..".
Thank you for any feedback you can provide.

I was always taught to code this as just a debridement code 11042-11047 depending on how deep he went. It wouldn't be a revision or a secondary closure. Or use cpt code 27301 if they have an abscess etc.. Sometimes for an infection I've even used the arthrotomy code 27310 depending on the Dr's op report.
