Decision Criteria
clinical Criteria
- Presence of simple partial seizures with preserved awareness.
Applicable To
- Simple partial seizures
Excludes
- Complex partial seizures
Clinical Validation Requirements
- EEG showing focal spikes in right frontal lobe
- Clinical description of left hand clonic movements with preserved awareness
Code-Specific Risks
- Risk of under-documenting the specific features of the seizure.
Coding Notes
- Ensure documentation specifies 'simple partial seizures' to avoid miscoding.

Use when the patient has focal symptomatic epilepsy with complex partial seizures.
Applicable To
- Complex partial seizures
Excludes
- Simple partial seizures
Clinical Validation Requirements
- Temporal lobe origin on MRI
- Clinical description of staring, lip-smacking, unresponsive for 60 seconds
Coding Notes
Ensure documentation specifies 'complex partial seizures' to avoid miscoding.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Focal Seizure to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G40.1xx.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with documentation standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Use templates to ensure all necessary details are captured.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of health data.
Mitigation Strategy
Query for more details to use specific codes like G40.1xx or G40.2xx.
Impact
Risk of audits due to non-specific seizure documentation.
Mitigation Strategy
Ensure detailed documentation of seizure characteristics and test results.
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.
