ICD-10 Code E67.0 – Hypervitaminosis A (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E67.0 – Hypervitaminosis A
What it is
E67.0 identifies excess vitamin A in the body, usually from overuse of supplements or other sources. It is used when documentation states vitamin A toxicity, overdose, or hypervitaminosis A.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include headache, nausea, vomiting, dizziness, skin changes, and other signs of vitamin A excess.
When to use this code
Use E67.0 when the clinician documents hypervitaminosis A, vitamin A toxicity, or a confirmed excess intake causing symptoms. It also fits follow-up encounters when the diagnosis remains active in the record. Check documentation if the chart only mentions supplement use without toxicity.
Do not use for
Do not use this code for normal vitamin supplementation or for nonspecific nutritional counseling. If the record does not clearly identify vitamin A excess, check documentation before assigning E67.0.
Coding tip
Look for explicit language such as “vitamin A toxicity” or “hypervitaminosis A” in the assessment, not just a history of supplement use.
