About F00ZDNZ

F00ZDNZ is the ICD-10-PCS code for a speech assessment procedure on the none using a fluency approach with biosensory feedback (qualifier: none). In ICD-10-PCS, speech assessment means measurement of speech and related functions.

In plain terms, this corresponds to other speech training and therapy, the ICD-9-CM procedure title it maps to (93.75).

The same procedure with a different approach is coded F00ZBNZ (motor speech), F00ZFNZ (voice) and F00ZNNZ (non-invasive instrumental status).

With a different device, use F00ZDKZ (audiovisual), F00ZDPZ (computer), F00ZDQZ (speech analysis), F00ZDSZ (voice analysis), F00ZDTZ (aerodynamic function), F00ZDYZ (other equipment) and 1 more.

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.
