Primary ICD-10-CM Code for gilbert's syndrome

Gilbert syndrome
Billable Code

Decision Criteria

clinical Criteria

  • Unconjugated hyperbilirubinemia with normal liver enzymes

coding Criteria

  • Ensure no mention of liver pathology

Applicable To

  • Gilbert's syndrome
  • Inherited disorder of bilirubin metabolism

Excludes

  • Crigler-Najjar syndrome (E80.5)
  • Dubin-Johnson syndrome (E80.6)

Clinical Validation Requirements

  • Unconjugated hyperbilirubinemia <6 mg/dL
  • Normal liver enzymes (ALT/AST <40 U/L)
  • Absence of hemolysis (normal LDH, haptoglobin)
  • Episodic jaundice triggered by fasting, stress, or illness

Code-Specific Risks

  • Confusion with other hyperbilirubinemias
  • Incorrect documentation of jaundice due to liver disease

Coding Notes

  • Always sequence E80.4 as primary for confirmed Gilbert’s.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Unspecified jaundice

R17
Use only if jaundice is present but Gilbert’s is not confirmed.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Crigler-Najjar syndrome

E80.5
Bilirubin >20 mg/dL, neonatal onset, neurologic symptoms

Dubin-Johnson syndrome

E80.6
Conjugated hyperbilirubinemia, dark liver on biopsy

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Gilbert's Syndrome to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E80.4.

Impact

Clinical: May lead to misdiagnosis., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials.

Mitigation Strategy

Always specify unconjugated vs. conjugated bilirubin., Ensure lab results are included.

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding standards., Data Quality: Inaccurate patient records.

Mitigation Strategy

Always code E80.4 when confirmed.

Impact

Risk of coding errors due to confusion with similar conditions.

Mitigation Strategy

Provide training on differentiating Gilbert syndrome from other hyperbilirubinemias.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Use these documentation templates to ensure complete and accurate documentation for Gilbert's Syndrome. These templates include all required elements for proper coding and billing.

Primary Care Visit

Specialty: Primary Care

Required Elements

  • Total bilirubin levels
  • Liver function tests
  • Absence of hemolysis

Example Documentation

Patient presents with mild jaundice. Total bilirubin 3.5 mg/dL (unconjugated 3.1 mg/dL). ALT 25 U/L, AST 20 U/L. Diagnosis: Gilbert syndrome.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has yellow eyes. Likely Gilbert’s.
Good Documentation Example
Total bilirubin 3.8 mg/dL (unconjugated 3.4 mg/dL), ALT 22 U/L, AST 18 U/L, normal CBC. No evidence of hemolysis. Consistent with Gilbert syndrome.
Explanation
The good example provides specific lab values and rules out other causes.
