About F00ZNTZ

F00ZNTZ is the ICD-10-PCS code for a speech assessment procedure on the none using a non-invasive instrumental status approach with aerodynamic function (qualifier: none). In ICD-10-PCS, speech assessment means measurement of speech and related functions.

In plain terms, this corresponds to functional evaluation, the ICD-9-CM procedure title it maps to (93.01).

The same procedure with a different approach is coded F00ZBTZ (motor speech), F00ZDTZ (fluency), F00ZFTZ (voice) and F00ZJTZ (instrumental swallowing and oral function).

With a different device, use F00ZNNZ (biosensory feedback), F00ZNPZ (computer), F00ZNQZ (speech analysis), F00ZNSZ (voice analysis) and F00ZNYZ (other equipment).

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.
