R94.12Abnormal results of function studies of ear and other special senses

R94.12 is the ICD-10-CM diagnosis code for abnormal results of function studies of ear and other special senses. It belongs to category R94 (abnormal results of function studies), block R90-R94 (abnormal findings on diagnostic imaging and in function studies, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within R94.1, choose R94.12 (ear and other special senses) only when documentation doesn't support a more specific option: eye (R94.11) and peripheral nervous system (R94.13).

To report this condition, pick the subcode that matches the documentation: R94.120 (study), R94.121 (study) and R94.128 (senses).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
