From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.
Intraoperative and postprocedural complications are coded from the body system chapters unless the complication is specifically indexed to a T code.
Excludes1
Not coded here. The listed conditions generally should not be reported together.
Excludes2

Notes
Also from chapter/block level (1 note)
- All neoplasms, whether functionally active or not, are classified in Chapter 2. Appropriate codes in this chapter (i.e. E05.8, E07.0, E16-E31, E34.-) may be used as additional codes to indicate either functional activity by neoplasms and ectopic endocrine tissue or hyperfunction and hypofunction of endocrine glands associated with neoplasms and other conditions classified elsewhere.
