Related ICD-10 Code Ranges

Complete code families applicable to Seizure Disorder

G40-G47Primary Range

Epilepsy and recurrent seizures

This range includes codes for epilepsy and recurrent seizures, which are primary for seizure disorders.

Convulsions, not elsewhere classified

This range is used for convulsions not classified under epilepsy, such as single seizures.

Dissociative and conversion disorders

Includes psychogenic non-epileptic seizures (PNES), which are important differential diagnoses.

CodeDescriptionWhen to UseKey Documentation
G40.909Epilepsy, unspecified, not intractable, without status epilepticusUse when epilepsy is confirmed but not further specified.
  • EEG showing epileptiform activity
  • Clinical history of ≥2 unprovoked seizures
R56.1Post traumatic seizuresUse for seizures directly following traumatic brain injury.
  • Seizure occurring ≤24h after trauma
  • No prior history of epilepsy
F44.5Conversion disorder with seizures or convulsionsUse for seizures with psychological origin confirmed by video-EEG.
  • Video-EEG showing no epileptiform activity during events

Clinical Decision Support

Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Key Information: ICD-10 code for seizure disorder

Essential facts and insights about Seizure Disorder

The ICD-10 code for unspecified seizure disorder is G40.909. For specific types, use codes like G40.219 for intractable epilepsy.

Billable Code

Decision Criteria

clinical Criteria

  • Confirmed diagnosis of epilepsy with unspecified type.

Applicable To

  • Unspecified epilepsy

Excludes

  • R56.9 (Unspecified convulsions)

Clinical Validation Requirements

  • EEG showing epileptiform activity
  • Clinical history of ≥2 unprovoked seizures

Code-Specific Risks

  • Overuse of unspecified codes can lead to audit risks.

Coding Notes

  • Ensure documentation specifies seizure type and frequency.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Unspecified abnormal involuntary movements

R25.9
Use for symptom management when specific seizure type is unclear.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Unspecified convulsions

R56.9
Use R56.9 for single seizures without a diagnosis of epilepsy.

Other generalized epilepsy and epileptic syndromes

G40.4
Use G40.4 for confirmed recurrent seizures post-trauma.

Epilepsy

G40.XXX
Use G40.XXX for confirmed epileptic seizures.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Seizure Disorder to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G40.909.

Impact

Clinical: Inaccurate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.

Mitigation Strategy

Use templates to ensure complete documentation., Regular training on seizure documentation.

Impact

Reimbursement: Incorrect coding can lead to lower reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data on epilepsy prevalence.

Mitigation Strategy

Use G40.XXX for confirmed epilepsy with recurrent seizures.

Impact

Frequent use of unspecified codes can trigger audits.

Mitigation Strategy

Ensure detailed documentation of seizure characteristics.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Example Documentation

Patient experiences complex partial seizures 2-3 times per month, despite medication.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Seizure disorder
Good Documentation Example
