Documentation Best Practices

Documentation Checklist
  • Elevated cholesterol, no specific type documented
  • Total cholesterol and LDL/HDL levels
  • Exclude familial hypercholesterolemia
  • Document lifestyle factors (diet, exercise)
  • Assess and document CHD risk factors

Coding and Audit Risks

Common Risks
  • Unspecified Code Use

    Coding High Cholesterol Unspecified (E78.9) when a more specific code is documented creates compliance risks and lost revenue.

  • Lack of Supporting Documentation

    Insufficient clinical documentation to support E78.9 diagnosis leads to denials and coding inaccuracies, impacting reimbursement.

  • Comorbidity Miscoding

    Failing to capture related conditions like hypertension or diabetes with E78.9 understates patient complexity and case mix index.

Mitigation Tips

Best Practices
  • Document LDL, HDL, triglycerides for accurate coding.
  • Query physician for specific type if possible (e.g., familial).
  • Review lipid panel for diagnosis confirmation per ICD-10 guidelines.
  • Code E78.5 only when type not documented per CDI best practices.
  • Ensure compliance with clinical indicators and payer policies.

Clinical Decision Support

Checklist
  • Review LDL, HDL, triglycerides levels
  • Document diet, exercise, FHx of dyslipidemia
  • Assess for secondary causes of hyperlipidemia
  • Consider statin therapy if indicated by guidelines
  • Patient education on lifestyle modifications

Documentation Templates

Patient presents with hypercholesterolemia, diagnosed as High Cholesterol Unspecified (ICD-10 E78.5).  Elevated cholesterol levels were noted during routine lipid panel screening.  The patient reports no specific symptoms related to high cholesterol such as chest pain or shortness of breath.  Family history is significant for hyperlipidemia and cardiovascular disease.  Current medications include (list medications).  Physical examination reveals no xanthoma or xanthelasma.  Dietary habits were reviewed, and the patient reports a diet moderate in fat.  Exercise habits consist of (describe patient's reported exercise).  Assessment includes high cholesterol, unspecified, likely familial combined hyperlipidemia given the family history.  Plan includes therapeutic lifestyle changes including dietary modifications with a focus on reducing saturated and trans fats, increasing soluble fiber intake, and increasing physical activity.  The patient was educated on the importance of cholesterol management for cardiovascular disease risk reduction.  Follow-up lipid panel in 3 months to assess response to lifestyle interventions.  Pharmacologic therapy with statins will be considered if lifestyle modifications are insufficient to achieve target lipid levels.  Patient education materials on cholesterol management and healthy lifestyle choices were provided.  Medical coding for this encounter includes E78.5 for high cholesterol unspecified, and additional codes may be added for relevant comorbidities or family history (e.g., Z82.4 for family history of ischemic heart disease).  Billing will reflect evaluation and management services provided.  The patient verbalized understanding of the diagnosis, treatment plan, and importance of follow-up.
