ValidICD-10-CM diagnosis code.

What has happened to this code
Every change the publisher made, from 2007 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

Official coding rules
Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
Inherited from D44 Neoplasm of uncertain behavior of endocrine glands
Excludes1 - never coded here
- multiple endocrine adenomatosis (E31.2-)
- multiple endocrine neoplasia (E31.2-)
- neoplasm of uncertain behavior of endocrine pancreas (D37.8)
- neoplasm of uncertain behavior of ovary (D39.1-)
- neoplasm of uncertain behavior of testis (D40.1-)
- neoplasm of uncertain behavior of thymus (D38.4)
Inherited from the D37-D48 section Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48)
