About F13Z83Z
F13Z83Z is the ICD-10-PCS code for a hearing assessment procedure on the none using a tone decay approach with tympanometer (qualifier: none). In ICD-10-PCS, hearing assessment means measurement of hearing and related functions.
In plain terms, this corresponds to other auditory and vestibular function tests, the ICD-9-CM procedure title it maps to (95.46).
The same procedure with a different approach is coded F13Z03Z (hearing screening), F13ZD3Z (tympanometry), F13ZF3Z (eustachian tube function), F13ZG3Z (acoustic reflex patterns), F13ZH3Z (acoustic reflex threshold) and F13ZJ3Z (acoustic reflex decay).
With a different device, use F13Z84Z (electroacoustic immitance / acoustic reflex) and F13Z8ZZ (none).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
