ICD-10 Code F06.7 – Mild neurocognitive disorder due to known physiological condition (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F06.7 – Mild neurocognitive disorder due to known physiological condition
What it is
Use this code for a mild decline in cognition caused by a known medical condition. It describes measurable problems with memory, attention, or other thinking skills that do not meet criteria for a major neurocognitive disorder.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include mild cognitive impairment with preserved independence, though the patient may need extra effort or compensatory strategies to manage daily tasks.
When to use this code
Assign F06.7 when the record links mild cognitive decline to a documented physiological cause, such as a neurologic, systemic, or other medical condition. Use it when the provider specifically identifies the disorder as mild and does not document a major neurocognitive disorder. Confirm the underlying condition is also documented and coded as instructed.
Do not use for
Do not use this code for normal age-related forgetfulness or for cognitive symptoms without a documented physiological cause. Check documentation if the record supports major neurocognitive disorder instead.
Coding tip
Code the underlying medical condition first or as directed, and verify that the provider explicitly supports the mild neurocognitive diagnosis.
