Chapter 6 guidelines
Diseases of the nervous system
G00-G99
Covers diseases of the nervous system, including epilepsy, migraine, and other neurological disorders.
Key coding points
- •Epilepsy codes distinguish between intractable and not intractable, and whether status epilepticus is present — documentation should be reviewed carefully for these qualifiers.
- •Pain-related neurological codes often need to be sequenced with the underlying condition per 'code first'/'use additional code' notes.
