What has happened to this code
Every change the publisher made, from 2012 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.
- FY2012 Added to the draft code set draft Neoplasm of uncertain behavior of breast
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 D48 Neoplasm of uncertain behavior of other and unspecified sites
Excludes1 - never coded here
- neurofibromatosis (nonmalignant) (Q85.0-)
Inherited from the D37-D48 section Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48)
Excludes1 - never coded here
- neoplasms of unspecified behavior (D49.-)
Note
- Categories D37-D44, and D48 classify by site neoplasms of uncertain behavior, i.e., histologic confirmation whether the neoplasm is malignant or benign cannot be made.
How CDC's index refers to this code
Wording from the official alphabetic index. Much of it appears nowhere in the code description, which is why a search for the everyday phrase so often finds nothing.
