Coding Notes for Section Q90-Q99
- Section Notes:
- Codes from this chapter are not for use on maternal or fetal records

Section Type-2 Excludes:
Type-2 Excludes
Type-2 Excludes means the excluded conditions are different, although they may appear similar. A patient may have both conditions, but one does not include the other. Excludes 2 means "not coded here." - Inborn errors of metabolism - instead, use Section E70-E88
