0.000What This Code Means
Epileptic spasms that can be controlled with medication, not currently in a prolonged seizure state.
Coding Tips
- •Use this code when spasms are responsive to treatment and status epilepticus is not present
- •Document the medication regimen to support the 'not intractable' designation
Clinical Significance
Epileptic spasms that respond to treatment without status epilepticus. This may represent successfully treated infantile spasms or ongoing spasm disorder in remission from status. Early treatment of epileptic spasms is critical to minimize developmental impact, and medication-responsive cases have a better long-term prognosis than intractable presentations.
Documentation Requirements
- ✓Documentation of epileptic spasms diagnosis
- ✓Confirmation spasms are controlled with medication (not intractable)
- ✓Absence of status epilepticus
- ✓Current treatment regimen (ACTH, vigabatrin, or other agents)
- ✓Developmental milestone tracking
- ✓EEG findings and seizure frequency
