About F013GZZ

F013GZZ is the ICD-10-PCS code for a motor and/or nerve function assessment procedure on the neurological system - whole body using a reflex integrity approach with none (qualifier: none). In ICD-10-PCS, motor and/or nerve function assessment means measurement of motor, nerve, and related functions.

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

For a different body part, codes include F010GZZ (neurological system - head and neck), F011GZZ (neurological system - upper back / upper extremity) and F012GZZ (neurological system - lower back / lower extremity).

The same procedure with a different approach is coded F0130ZZ (muscle performance), F0131ZZ (integumentary integrity), F0133ZZ (coordination/dexterity), F0134ZZ (motor function), F0135ZZ (range of motion and joint integrity) and F0136ZZ (sensory awareness/processing/integrity).

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.
