Wiki Need help with diagnosis code-I am having

[coder25]

I am having difficulty finding a diagnosis code for a gastrocutaneous fistula with abscess. I can find other fistulas, but nothing talking about the cutaneous part. Would I just use the abscess code?

Thanks for your help.

I would use 537.4 as it covers all fistula of the stomach or duodenum
