About F13ZK7Z
F13ZK7Z is the ICD-10-PCS code for a hearing assessment procedure on the none using an electrocochleography approach with electrophysiologic (qualifier: none). In ICD-10-PCS, hearing assessment means measurement of hearing and related functions.
In plain terms, this corresponds to Electrocochleography, the ICD-9-CM procedure title it maps to (20.31).
The same procedure with a different approach is coded F13ZL7Z (auditory evoked potentials).
With a different device, use F13ZKZZ (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.
