Excludes1 — never code together — inherited from J33
The conditions below can never be reported together with J33.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- adenomatous polyps (D14.0)
Use additional code — inherited from Chapter 10
Report an additional code alongside J33.1 to fully describe the condition. J33.1 is sequenced first.
