Oth sequelae following nontraumatic subarachnoid hemorrhage

This code signifies long-term neurological or physical deficits that persist after a patient has experienced a nontraumatic subarachnoid hemorrhage (SAH). These sequelae are not acute manifestations of the SAH but rather residual effects that develop or remain after the initial event has resolved. Examples include cognitive impairment, motor deficits, or speech difficulties.

Use this code when documenting chronic, residual conditions directly attributable to a nontraumatic SAH that occurred in the past. This applies when the patient is no longer in the acute phase of the hemorrhage. Documentation should clearly link the current sequelae to a previously diagnosed nontraumatic SAH and specify the nature of the residual deficit.

• Always sequence the specific neurological or physical sequela (e.g., hemiplegia, aphasia) first, followed by this code as a secondary diagnosis to indicate the etiology.
• Ensure documentation explicitly states "sequelae of" or "due to prior" nontraumatic subarachnoid hemorrhage to support code assignment.
• Distinguish from codes for acute or active subarachnoid hemorrhage (I60.-) or sequelae of traumatic subarachnoid hemorrhage (S06.6-, T90.5).
