For skin biopsies that come back "granuloma" without an mention of a foreign body, or "granulomatous changes" without mention of foreign body - which code do you use? The book says that for "Granuloma NEC" use 686.1. I was interested if ICD-10 was any more specific. For "Granuloma, skin" ICD-10 uses L92.9 which converts to 701.5 (Granulation tissue) in ICD-9. So, I'm thinking, for my given cases, should I use 686.1 or 701.5, or something else to best describe it?
