About F13Z8ZZ

F13Z8ZZ is the ICD-10-PCS code for a hearing assessment procedure on the none using a tone decay approach with none (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 F13Z0ZZ (hearing screening), F13Z1ZZ (pure tone audiometry, air), F13Z2ZZ (pure tone audiometry, air and bone), F13Z3ZZ (bekesy audiometry), F13Z4ZZ (conditioned play audiometry), F13Z5ZZ (select picture audiometry) and 16 more.

With a different device, use F13Z83Z (tympanometer) and F13Z84Z (electroacoustic immitance / acoustic reflex).

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.
