Coma scale, best motor response, abnormal flexion, admit

This code indicates a specific finding during a neurological assessment, representing a Glasgow Coma Scale (GCS) motor response of abnormal flexion to pain. This motor response, also known as decorticate posturing, suggests significant brain dysfunction, typically at the level of the cerebral hemispheres. It is documented specifically at the time of a patient's admission to the hospital.

Use this code when documentation clearly states a GCS motor score of 3, characterized by abnormal flexion (decorticate posturing) in response to a noxious stimulus, recorded upon the patient's arrival at the hospital. This is often seen in patients with severe traumatic brain injury, stroke, or other acute neurological insults. Supporting documentation would include GCS assessments from emergency department notes, admission orders, or initial neurological evaluations.

• Ensure the documentation specifies "abnormal flexion" and not merely "flexion withdrawal" (GCS motor score 4), as these are distinct findings.
• Verify that the GCS assessment was performed and documented at hospital admission to accurately apply this code.
• This code is a symptom code and should be sequenced after the definitive diagnosis for the underlying condition causing the altered mental status, if known.
