Neoplasm of unspecified behavior of brain
ValidICD-10-CM diagnosis code.
Valid for claims with a date of service in the current code year.
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.
- FY2007 Added to the draft code set draft Neoplasm of unspecified behavior of brain
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 D49 Neoplasms of unspecified behavior
Excludes2 - not included here
- neoplasms of uncertain behavior (D37-D44, D48)
Includes
- 'growth' NOS
- neoplasm NOS
- new growth NOS
- tumor NOS
Note
- Category D49 classifies by site neoplasms of unspecified morphology and behavior. The term 'mass', unless otherwise stated, is not to be regarded as a neoplastic growth.
