Personal history of dis of the nervous sys and sense organs

This code indicates a patient's past medical history of a neurological or sensory organ disease that is no longer active and is not a sequela of a cerebrovascular disease. It signifies that the patient previously had a condition affecting the nervous system or senses, but it has resolved or is in remission.

Use this code when documenting a patient's history of conditions such as resolved migraines, past Bell's Palsy, or a history of optic neuritis, where these conditions are not currently active and are not related to a stroke or TIA. It is appropriate for follow-up visits where the historical condition is relevant to current care but not the primary reason for the encounter.

• Always sequence this code as a secondary diagnosis, as it represents a historical condition, not an active problem.
• Ensure the specific neurological or sensory condition is not better represented by a more specific history code (e.g., history of CVA).
• Verify that the condition is truly resolved or in remission and not an ongoing, active disease process.
