Pure hypercholesterolemia

This code signifies an isolated elevation of low-density lipoprotein (LDL) cholesterol in the blood, without significant elevation of triglycerides. It represents a primary lipid disorder characterized by high cholesterol levels, often due to genetic predisposition or dietary factors.

Apply this code when documentation clearly indicates hypercholesterolemia as the primary or sole lipid abnormality. This is appropriate for patients diagnosed with familial hypercholesterolemia or diet-induced hypercholesterolemia where triglyceride levels are within normal limits.

• Ensure documentation specifies "pure" or "isolated" hypercholesterolemia, or explicitly states normal triglyceride levels.
• Do not use if hypertriglyceridemia or mixed hyperlipidemia is also present; consider codes for mixed dyslipidemia instead.
• This code is often sequenced as a primary diagnosis when managing the patient's hypercholesterolemia.
