General information only — not a diagnosis or medical advice. Only a doctor can say what this code means for you. Seek medical help for anything urgent or worrying.
What it generally refers to
This code covers raised levels of fats (lipids) in the blood when the exact pattern is not specified. High cholesterol usually causes no symptoms but raises the long-term risk to the heart and blood vessels. It is managed with diet, activity and, when needed, medication.
Reading it in context
Codes like E78.5 are written for records and billing, so they are short by design. The same code can sit behind very different real situations, and the plan that matters — tests, treatment, follow-up — lives in the rest of your notes and in what your clinician tells you, not in the code alone.
