Autoimmune thyroiditis

This range includes Hashimoto's disease and is used for coding autoimmune thyroiditis.

Key Information: Hashimoto's disease ICD-10 code

Essential facts and insights about Hashimoto's Disease

Hashimoto's disease is coded as E06.3 in ICD-10, which includes autoimmune thyroiditis.

Primary ICD-10-CM Code for hashimoto's disease

Autoimmune thyroiditis
Billable Code

Decision Criteria

clinical Criteria

  • Presence of elevated TPO antibodies and hypothyroidism symptoms.

coding Criteria

  • Do not pair with E03.9 when Hashimoto's is documented.

Applicable To

  • Hashimoto's thyroiditis
  • Chronic lymphocytic thyroiditis

Excludes

  • Acute thyroiditis (E06.0)
  • Subacute thyroiditis (E06.1)

Clinical Validation Requirements

  • Elevated TPO antibodies
  • TSH >10 mIU/L
  • Ultrasound showing hypoechoic thyroid

Code-Specific Risks

  • Misuse with E03.9 for hypothyroidism due to Hashimoto's

Coding Notes

  • Ensure documentation specifies autoimmune nature to use E06.3.

Ancillary Codes

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

Long-term (current) use of insulin

Z79.4
Use when patient is on long-term thyroid hormone replacement.

Differential Codes

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

Hypothyroidism, unspecified

E03.9
Use E03.9 only if hypothyroidism is documented without an autoimmune cause.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Hashimoto's Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E06.3.

Impact

Clinical: Misdiagnosis of thyroid condition., Regulatory: Non-compliance with ICD-10 coding standards., Financial: Potential claim denials.

Mitigation Strategy

Ensure thorough documentation of lab results., Educate providers on coding guidelines.

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate data on thyroiditis prevalence.

Mitigation Strategy

Use E06.3 alone as it encompasses hypothyroidism due to autoimmune thyroiditis.

Impact

Inadequate documentation of TPO antibodies and thyroid ultrasound.

Mitigation Strategy

Implement regular training on documentation standards.

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.

Frequently Asked Questions

Common questions about ICD-10 coding for Hashimoto's Disease, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Hashimoto's Disease

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

Routine Endocrinology Visit

Specialty: Endocrinology

Required Elements

  • Diagnosis of Hashimoto's thyroiditis
  • TSH and TPO antibody levels
  • Ultrasound findings

Example Documentation

Patient presents with elevated TSH and TPO antibodies. Diagnosis: Hashimoto's thyroiditis. Plan: Adjust levothyroxine dosage.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Thyroid disorder, monitor TSH.
Good Documentation Example
Autoimmune hypothyroidism (Hashimoto's) with TSH 15.2 mIU/L and TPO antibodies >600 IU/mL, on levothyroxine 75mcg daily.
Explanation
The good example specifies the autoimmune nature and provides lab values.
