In neurological and primary care practice, patients with a personal history of seizures require thoughtful long-term care, risk stratification, and precise documentation. Whether the seizures are due to epilepsy, post-traumatic injury, or isolated febrile events, recognizing and coding their history accurately is essential for patient safety, continuity of care, and compliance.
In this article, we’ll cover:
-
What constitutes a personal history of seizures
-
Why it matters for long-term medical management
-
ICD-10 coding using Z86.69
-
Documentation strategies

How DocScrib supports seamless, neurologically relevant documentation
What Is Meant by a Personal History of Seizures?
A personal history of seizures refers to any past episodes of seizure activity, regardless of current seizure control or diagnosis. These episodes may include:
-
Generalized tonic-clonic seizures
-
Focal onset seizures (with or without awareness)
-
Febrile seizures (in childhood)
-
Status epilepticus
-
Seizures secondary to trauma, tumors, or metabolic causes
The key point is that the patient is not currently having a seizure, but their history influences clinical decisions, medication plans, driving restrictions, and more.
Why This History Matters Clinically
A patient’s seizure history can impact several areas of care:
Medication Safety
-
Avoid medications that lower seizure threshold
-
Adjust doses of AEDs (Anti-Epileptic Drugs) in renal/hepatic impairment
-
Monitor for drug interactions with antibiotics, antidepressants, etc.
Anesthesia and Surgery Risk
-
Higher risk of intra/post-operative seizures
-
Need for seizure prophylaxis during CNS surgeries
Driving and Licensing
-
Many regions require a seizure-free period for driver’s license eligibility
-
Accurate documentation affects legal standing and insurance forms
Pregnancy and Reproductive Health
-
Epilepsy history influences medication choices, folic acid dosing
-
Higher risks during pregnancy, including preeclampsia and fetal complications
ICD-10 Coding for Personal History of Seizures
Primary ICD-10 Code
Z86.69 – Personal history of other diseases of the nervous system and sense organs
This code includes:
➡️ Personal history of epilepsy or seizure disorders (no longer active or under control)
⚠️ Do not use this code if the patient is experiencing current seizures—that requires G40.x series codes for epilepsy.
Related ICD-10 Codes
ICD-10 Code | Description |
---|---|
G40.909 | Epilepsy, unspecified, not intractable |
R56.9 | Unspecified convulsions |
Z91.19 | Patient noncompliance with medication |
Z79.899 | Long-term current use of anti-epileptics |
Documenting Seizure History in the Medical Record
When charting a history of seizures, clarity and specificity help ensure:
✅ Proper coding
✅ Better risk stratification
✅ Optimized care coordination
✅ Legal protection (especially in cases involving driving, school/work clearance)
What to Include in the Note
-
Date or age at first seizure
-
Last seizure occurrence (if known)
-
Type of seizure(s) experienced
-
Ongoing medication and adherence
-
Comorbid conditions (e.g., TBI, stroke, alcohol use)
-
Known triggers (stress, sleep deprivation, photic stimuli)
Sample Documentation (SOAP Note Style)
Subjective:
“Patient reports history of generalized seizures during teenage years. Last episode was at age 22. Currently on lamotrigine, no recent events.”
Objective:
Normal neuro exam. Vitals stable. No seizure activity observed. Review of systems negative for aura or confusion.
Assessment:
Personal history of epilepsy, currently seizure-free for 8 years. Continues AED maintenance.
ICD-10 Code: Z86.69
Plan:
-
Continue lamotrigine 100mg BID
-
Routine EEG in 6 months
-
Educate patient on seizure triggers and medication adherence
Challenges in Seizure History Documentation
🚫 Overuse of current seizure codes (G40.x) for resolved cases
🚫 Missing detail about duration or remission status
🚫 No mention of current AED use
🚫 Uncoded prior seizure episodes in chronic care settings
These gaps can result in incorrect problem lists, denied claims, and incomplete clinical profiles.
Special Considerations by Patient Population
Pediatrics
-
Febrile seizures often resolve but still warrant documentation
-
Important for school forms, sports clearance, future anesthesia risk
Elderly
-
Stroke-related or post-traumatic seizures may not recur
-
Medication interactions and polypharmacy increase risks
-
Falls, dementia, and memory issues may obscure true seizure frequency
Pregnancy
-
AED monitoring essential
-
Multidisciplinary care with neurologist and OB-GYN

Quick Reference Table: Seizure-Related ICD-10 Coding
Scenario | ICD-10 Code(s) |
---|---|
Personal history of epilepsy | Z86.69 |
Active epilepsy (unspecified) | G40.909 |
Single seizure episode, resolved | Z86.69 |
Febrile seizure history | Z86.69 |
Seizure from head trauma, not recurring | Z86.69 |
Long-term AED use | Z79.899 |
Current seizure with hospitalization | G40.901 + R56.9 |
FAQs
Q1: Is Z86.69 appropriate for someone with well-controlled epilepsy?
Yes. If the patient has had seizures in the past and is currently not experiencing events, Z86.69 is correct—even if they’re on medications.
Q2: Should I also include the medication code (Z79.899)?
Yes, if the patient is on long-term anti-seizure meds. This reflects chronic disease management in billing and audit reports.
Q3: How can I make my seizure notes audit-ready?
Include seizure type, last episode date, medication adherence, and potential triggers. Tools like DocScrib automate these inserts.
Q4: Does seizure history affect procedural clearance (MRI, surgery)?
Absolutely. Personal seizure history can affect anesthesia planning and pre-procedure precautions.
Q5: Can DocScrib document neurologic exams and seizure control status?
Yes. DocScrib supports neurology templates, tracks seizure-free intervals, and syncs with follow-up reminders.
Conclusion
Seizure history documentation is more than a checkbox—it’s a vital signal in a patient’s longitudinal care journey. Using ICD-10 Z86.69 appropriately ensures better outcomes, risk mitigation, and compliance.
With tools like DocScrib, clinicians can automate seizure documentation, minimize errors, and maximize productivity.
