2021 ICD-10-CM Code R94.09
Abnormal results of other function studies of central nervous system
Valid for Submission
R94.09 is a billable diagnosis code used to specify a medical diagnosis of abnormal results of other function studies of central nervous system. The code R94.09 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code R94.09 might also be used to specify conditions or terms like abnormal auditory evoked potential, abnormal auditory evoked potential, abnormal auditory evoked potential, abnormal auditory evoked potential, abnormal auditory evoked potential , abnormal auditory evoked potential, etc.
According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.
| ICD-10: | R94.09 |
| Short Description: | Abnormal results of function studies of cnsl |

Convert R94.09 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code R94.09 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
