About F0DZ55Z

F0DZ55Z is the ICD-10-PCS code for a device fitting procedure on the none using an assistive listening device approach with hearing aid selection / fitting / test (qualifier: none). In ICD-10-PCS, device fitting means fitting of a device designed to facilitate or support achievement of a higher level of function.

In plain terms, this corresponds to fitting of hearing aid, the ICD-9-CM procedure title it maps to (95.48).

The same procedure with a different approach is coded F0DZ05Z (tinnitus masker), F0DZ15Z (monaural hearing aid) and F0DZ25Z (binaural hearing aid).

With a different device, use F0DZ51Z (audiometer), F0DZ52Z (sound field / booth), F0DZ5KZ (audiovisual), F0DZ5LZ (assistive listening) and F0DZ5ZZ (none).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 945 (Rehabilitation with CC/MCC) and DRG 946 (Rehabilitation without CC/MCC), under the surgical category “Rehabilitation”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
