ICD-10 Code E67.3 – Hypervitaminosis D (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E67.3 – Hypervitaminosis D
What it is
Hypervitaminosis D means too much vitamin D in the body. Use this code when documentation states vitamin D excess, overdose, or toxicity from vitamin D intake.
Clinical signs
Clinical features vary; refer to documentation. Patients may have findings consistent with vitamin D excess, such as nonspecific gastrointestinal, neurologic, or kidney-related complaints, but you should code only what is documented.
When to use this code
Use E67.3 when the provider diagnoses hypervitaminosis D, vitamin D toxicity, or excess vitamin D without a more specific poisoning code. It may also apply when the record identifies accidental overuse of supplements and confirms vitamin D excess. Check documentation if the case is described as poisoning, adverse effect, or underdosing.
Do not use for
Do not use this code for routine vitamin D supplementation, deficiency, or unspecified abnormal vitamin D labs alone. If the record documents poisoning or adverse effect from a medication or supplement, use the appropriate code set instead.
Coding tip
Code E67.3 only when the chart clearly links the diagnosis to excess vitamin D, not just a supplement history.
