Understanding Familial Hypercholesterolemia (FH)? This resource provides essential information for healthcare professionals on diagnosing and documenting FH, also known as Hereditary Hypercholesterolemia. Learn about relevant medical coding terms, clinical documentation best practices, and the importance of accurate FH diagnosis for effective patient care.
Also known as
Pure hypercholesterolemia
Elevated cholesterol levels without other lipid abnormalities.
Mixed hyperlipidemia
Elevated cholesterol and triglycerides.
Hyperlipidemia, unspecified
Elevated lipids without further specification.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the hypercholesterolemia familial/hereditary?
Yes
Is there tendon xanthoma?
No
Do NOT code as familial hypercholesterolemia. Code the underlying cause of the hypercholesterolemia if known.
When to use each related code
| Description |
|---|
| High cholesterol passed down through families. |
| High cholesterol not due to genetics. |
| Mixed high cholesterol with both genetic and lifestyle factors. |
Coding FH requires definitive genetic or clinical confirmation. Coding without sufficient documentation leads to overcoding and compliance risks.
Distinguishing between clinical FH and genetically confirmed FH is crucial for accurate coding and reimbursement.
Misdiagnosis of secondary causes (e.g., diet, hypothyroidism) as FH can lead to incorrect coding and treatment.
Q: What are the most effective strategies for diagnosing Familial Hypercholesterolemia (FH) in asymptomatic pediatric patients with a positive family history?
A: Diagnosing Familial Hypercholesterolemia (FH) in asymptomatic pediatric patients with a positive family history requires a multi-pronged approach. First, obtain a detailed family history focusing on premature cardiovascular disease and elevated cholesterol levels. Second, perform a lipid panel, specifically looking for elevated LDL-C levels. For children aged 2-10 years with a positive family history of FH, an LDL-C level >130 mg/dL is suggestive, while in those aged 10-19, a level >160 mg/dL is concerning. Genetic testing can be considered to confirm the diagnosis and identify the specific mutation, especially in ambiguous cases or for cascade screening purposes. Physical examination should assess for xanthomas, which are cholesterol deposits, though these are less common in children. It's crucial to differentiate FH from other causes of hyperlipidemia. Early diagnosis is critical for initiating timely lifestyle interventions and potential pharmacotherapy to minimize long-term cardiovascular risk. Explore how genetic testing can be integrated into your pediatric FH diagnostic workflow.
Q: How can I differentiate between Familial Hypercholesterolemia (FH) and other causes of significantly elevated LDL cholesterol in adults, especially when considering potential secondary causes?
A: Differentiating Familial Hypercholesterolemia (FH) from other causes of significantly elevated LDL cholesterol requires careful consideration of clinical presentation, family history, and laboratory findings. While a significantly elevated LDL-C is a hallmark of FH, secondary causes such as hypothyroidism, nephrotic syndrome, and certain medications (e.g., corticosteroids, protease inhibitors) must be ruled out. Obtain a thorough medical history, including medication use, and conduct laboratory tests to evaluate thyroid function and renal function. A detailed family history of premature cardiovascular disease or elevated cholesterol levels strongly suggests FH. Physical examination for tendon xanthomas and corneal arcus can provide additional clues. Genetic testing is the gold standard for confirming FH and differentiating it from other forms of hypercholesterolemia. Consider implementing a clinical diagnostic score, such as the Dutch Lipid Clinic Network Criteria or the Simon Broome Register criteria, to aid in risk stratification.

Patient presents with concerns regarding familial hypercholesterolemia (FH), also known as hereditary hypercholesterolemia. The patient reports a family history of high cholesterol and premature coronary artery disease. Physical examination reveals xanthelasmas and corneal arcus, raising suspicion for FH. Lipid panel demonstrates significantly elevated LDL cholesterol levels exceeding 190 mgdL in an adult or 160 mgdL in a child, further supporting the diagnosis. Diagnostic workup may include genetic testing for FH mutations such as LDLR, APOB, and PCSK9. The patient's clinical presentation, family history, and laboratory findings meet the diagnostic criteria for probable familial hypercholesterolemia. Treatment plan focuses on aggressive lipid-lowering therapy to reduce cardiovascular risk. This includes statin therapy at the maximum tolerated dose, with consideration for additional medications such as ezetimibe or PCSK9 inhibitors. Lifestyle modifications, including dietary changes focusing on a low saturated fat and low cholesterol diet, and regular exercise, are also emphasized. Patient education regarding the genetic basis of FH and the importance of cascade screening for family members is provided. Follow-up appointments are scheduled to monitor lipid levels, assess treatment efficacy, and adjust medications as needed. ICD-10 code E78.01 is used for this diagnosis. The patient will be counseled on the long-term management of FH and the need for ongoing monitoring and adherence to the prescribed treatment plan.
