Unspecified sequelae of nontraumatic subarachnoid hemorrhage

This code describes the long-term effects or residual conditions resulting from a subarachnoid hemorrhage that was not caused by trauma. These sequelae can include a range of neurological deficits, cognitive impairments, or other persistent health problems that manifest after the acute phase of the hemorrhage has resolved. The "unspecified" nature indicates that the specific type of sequela is not documented or known.

Use this code when a patient presents with a chronic condition or deficit clearly attributed to a past nontraumatic subarachnoid hemorrhage, but the specific nature of that sequela is not detailed in the medical record. This is appropriate for follow-up visits or when managing long-term complications where the precise neurological or physical manifestation is not specified. Documentation should clearly link the current condition to a history of nontraumatic subarachnoid hemorrhage.

• Always attempt to code to the highest level of specificity; only use this code if the specific sequela (e.g., aphasia, hemiplegia) is truly unspecified.
• Do not use this code for the acute subarachnoid hemorrhage itself; this code is exclusively for the sequelae.
• Consider sequencing this code after any more specific codes describing the current manifestation of the sequela, if applicable and documented.
