About F0100EZ
F0100EZ is the ICD-10-PCS code for a motor and/or nerve function assessment procedure on the neurological system - head and neck using a muscle performance approach with orthosis (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 manual testing of muscle function, the ICD-9-CM procedure title it maps to (93.04).
For a different body part, codes include F0110EZ (neurological system - upper back / upper extremity), F0120EZ (neurological system - lower back / lower extremity), F0130EZ (neurological system - whole body), F01D0EZ (integumentary system - head and neck), F01F0EZ (integumentary system - upper back / upper extremity), F01G0EZ (integumentary system - lower back / lower extremity) and 6 more.
With a different device, use F0100FZ (assistive, adaptive, supportive or protective), F0100UZ (prosthesis), F0100YZ (other equipment) and F0100ZZ (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.
