Abnormal vestibular function study
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 Abnormal vestibular function study
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 R94 Abnormal results of function studies
Includes
- abnormal results of radionuclide [radioisotope] uptake studies
- abnormal results of scintigraphy
Inherited from the R90-R94 section Abnormal findings on diagnostic imaging and in function studies, without diagnosis (R90-R94)
Excludes1 - never coded here
- abnormal findings on antenatal screening of mother (O28.-)
- diagnostic abnormal findings classified elsewhere - see Alphabetical Index
Includes
- nonspecific abnormal findings on diagnostic imaging by computerized axial tomography [CAT scan]
- nonspecific abnormal findings on diagnostic imaging by magnetic resonance imaging [MRI][NMR]
- nonspecific abnormal findings on diagnostic imaging by positron emission tomography [PET scan]
- nonspecific abnormal findings on diagnostic imaging by thermography
- nonspecific abnormal findings on diagnostic imaging by ultrasound [echogram]
- nonspecific abnormal findings on diagnostic imaging by X-ray examination
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.
