2026 ICD-10-CM Diagnosis Code G93.43 – Leukoencephalopathy with calcifications and cysts
What it is
G93.43 identifies a rare brain white-matter disorder marked by calcifications and cyst formation. Use it when documentation specifically names leukoencephalopathy with calcifications and cysts.
Clinical signs
Clinical features vary; refer to documentation. Reported findings may include neurologic deficits, seizures, headaches, or progressive cognitive changes, along with imaging evidence of calcifications and cysts.
When to use this code
Use this code when the provider diagnoses leukoencephalopathy with calcifications and cysts, or documents the condition by name in the assessment. It may also fit when imaging and specialist notes clearly support the diagnosis. Check documentation if the record only describes nonspecific white-matter changes.
Do not use for
Do not use G93.43 for general leukoencephalopathy, isolated intracranial calcifications, or brain cysts without this specific diagnosis. Check documentation if the condition is suspected but not confirmed.
Coding tip
Code only when the full named disorder is documented; otherwise, query for clarification.
