ICD-10 Code F13.27 – Sedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced persisting dementia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.27 – Sedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced persisting dementia
What it is
This code identifies dependence on sedative, hypnotic, or anxiolytic drugs with a persisting dementia caused by those substances. Use it when documentation links the cognitive disorder to the drug use and dependence.
Clinical signs
Clinical features may include persistent memory loss, impaired judgment, and reduced ability to perform everyday tasks. Clinical features vary; refer to documentation for evidence of substance-induced dementia and ongoing dependence.
When to use this code
Use this code when the record states both sedative, hypnotic, or anxiolytic dependence and a persisting dementia attributed to that substance. It is appropriate when the dementia remains after intoxication or withdrawal has resolved. Check documentation for the causal relationship and whether the diagnosis is current.
Do not use for
Do not use this code for uncomplicated sedative dependence without dementia, or for dementia with another documented cause. If the chart does not clearly connect the dementia to the substance, check documentation.
Coding tip
Code the substance dependence and the persisting dementia only when the provider explicitly documents both conditions and their relationship.
