In simple words: This code describes weakness or paralysis on one side of the body that happened after a brain bleed (not caused by an injury). The bleed was in an area of the brain that doesn't control dominant functions like speech or writing.

This ICD-10-CM code classifies hemiplegia (paralysis affecting one side of the body) and hemiparesis (weakness affecting one side of the body) as sequelae of a nontraumatic subarachnoid hemorrhage (bleeding into the space between the brain and its surrounding membranes) specifically affecting the left non-dominant side of the brain.The condition is a result of cerebrovascular disease.

Example 1: A 65-year-old female presents with sudden onset of left-sided weakness and facial droop following a spontaneous subarachnoid hemorrhage.Neurological exam reveals hemiparesis.Imaging confirms a subarachnoid hemorrhage without evidence of trauma. The left side is non-dominant, meaning speech is not affected, consistent with I69.054., A 72-year-old male with a history of hypertension experienced a sudden, severe headache followed by weakness in his left arm and leg.CT scan revealed a subarachnoid hemorrhage, and neurological examination revealed left-sided hemiparesis involving the non-dominant hemisphere. His speech remained unaffected, making I69.054 the appropriate code., An 80-year-old woman is admitted with altered mental status and left-sided weakness.She had a prior history of uncontrolled hypertension.Brain imaging confirmed a nontraumatic subarachnoid hemorrhage, and subsequent neurologic examination revealed left-sided hemiparesis.She is left-handed which is why the left side would be her non-dominant side, leading to the use of I69.054.

Detailed neurological examination findings,imaging reports (CT scan or MRI) demonstrating the subarachnoid hemorrhage location and extent,description of the patient's functional deficits (e.g., weakness, paralysis),and assessment of the affected hemisphere (dominant vs. non-dominant) should be documented.Any risk factors (hypertension, anticoagulant use) must be included.

** This code specifically addresses hemiplegia and hemiparesis following a nontraumatic subarachnoid hemorrhage.It is crucial to distinguish this from conditions with similar presentations but different etiologies (e.g., stroke, traumatic brain injury).Accurate documentation of the laterality (left side) and hemispheric dominance is critical for correct coding.
