Clinical Classification Guidelines
Clinical Notes
Assign a code from subcategory R40.24, when only the total coma score is documented
7th Character Definition
The following appropriate 7th character is to be added to subcategory R40.24-:
Medical Intelligence & Overview
The Glasgow Coma Scale (GCS) is a clinical tool used by healthcare professionals to assess a patient's level of consciousness after a brain injury or other medical conditions affecting brain function. When documenting a patient's neurological status, the total score from the GCS provides a quick and standardized measure of consciousness. The ICD-10 code R40.24 is specifically used when only the total GCS score is recorded, offering a concise way to categorize and communicate the patient's neurological state.
Causes & Symptoms
Clinical Causes: Traumatic brain injury (e.g., concussion, skull fracture, contusion) Stroke or cerebrovascular accident Brain tumors or masses Infections such as meningitis or encephalitis Metabolic disturbances (e.g., hypoglycemia, hepatic encephalopathy) Intoxication from substances like alcohol or drugs Seizures or post-ictal states Neurosurgical procedures
Key Symptoms: Altered level of consciousness ranging from mild confusion to coma Reduced responsiveness to stimuli Abnormal postures or muscle responses Pupillary changes indicating brain involvement Respiratory irregularities Impaired eye movements or pupil reflexes Swallowing difficulties in severe cases
Diagnostic & Treatment
Diagnosis Path: To determine the patient's GCS score, healthcare providers evaluate three aspects: eye opening, verbal response, and motor response. Each category has a scoring system, with points summed to give the total GCS score, which ranges from 3 (deep coma or death) to 15 (fully alert). When only the total score is documented, the ICD-10 code R40.24 is used to indicate this specific measurement. An accurate assessment helps in diagnosing the severity of brain impairment, monitoring progress, and planning treatment.
Treatment Protocols: Management of altered consciousness or brain injury depends on the underlying cause. Common approaches include:
