What This Code Means

Sjögren syndrome affecting the brain and spinal cord, which can cause cognitive problems, headaches, or neurological symptoms.

Coding Tips

•Document specific CNS manifestations such as encephalitis, myelitis, or cognitive dysfunction.
•MRI findings and cerebrospinal fluid analysis may support this diagnosis.

Clinical Significance

Sjögren syndrome with central nervous system involvement represents the most severe form of extra-glandular manifestations, potentially causing cognitive impairment, seizures, or other neurological deficits. This requires immediate neurological evaluation and aggressive treatment.

Documentation Requirements

✓Confirmed diagnosis of Sjögren syndrome
✓Neurological symptoms affecting brain or spinal cord
✓Brain MRI or other CNS imaging abnormalities
✓Cerebrospinal fluid analysis if performed
✓Neuropsychological testing results if cognitive involvement
✓Neurology consultation and recommendations
✓Exclusion of other causes of CNS symptoms
