About F13ZD4Z

F13ZD4Z is the ICD-10-PCS code for a hearing assessment procedure on the none using a tympanometry approach with electroacoustic immitance / acoustic reflex (qualifier: none). In ICD-10-PCS, hearing assessment means measurement of hearing and related functions.

In plain terms, this corresponds to Audiometry, the ICD-9-CM procedure title it maps to (95.41).

The same procedure with a different approach is coded F13Z84Z (tone decay), F13ZF4Z (eustachian tube function), F13ZG4Z (acoustic reflex patterns), F13ZH4Z (acoustic reflex threshold), F13ZJ4Z (acoustic reflex decay) and F13ZP4Z (aural rehabilitation status).

With a different device, use F13ZD3Z (tympanometer) and F13ZDZZ (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.
