Billable Code

Decision Criteria

clinical Criteria

  • TRAb positivity and suppressed TSH without goiter specification.

coding Criteria

  • Absence of thyroid storm or specific goiter type in documentation.

Applicable To

  • Graves' disease unspecified

Excludes

  • Thyrotoxicosis with diffuse goiter (E05.00)
  • Thyrotoxicosis with thyrotoxic crisis or storm (E05.01)

Clinical Validation Requirements

  • TRAb positivity
  • Suppressed TSH levels
  • Elevated T4 levels

Code-Specific Risks

  • Misclassification if goiter type or crisis is documented but not coded.

Coding Notes

  • Ensure documentation supports the use of E05.90 by confirming the absence of specific goiter type or crisis.

Ancillary Codes

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

Exophthalmic conditions

H05.2-
Use if Graves’ orbitopathy is present.

Differential Codes

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

Thyrotoxicosis with diffuse goiter

E05.00
Use if documentation specifies diffuse goiter.

Thyrotoxicosis with thyrotoxic crisis or storm

E05.01
Use if documentation specifies thyrotoxic crisis.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Graves' Disease Unspecified to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E05.90.

Impact

Clinical: Potential misdiagnosis of thyrotoxicosis type., Regulatory: Non-compliance with documentation standards., Financial: Possible claim denials due to lack of specificity.

Mitigation Strategy

Ensure TRAb tests are ordered and results documented.

Impact

Reimbursement: Incorrect coding may lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Use E05.00 instead.

Impact

Frequent use of unspecified codes without supporting documentation.

Mitigation Strategy

Ensure detailed documentation of thyroid imaging and lab results.

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.

Endocrinology follow-up for Graves' disease

Specialty: Endocrinology

Required Elements

  • TRAb levels
  • Thyroid ultrasound results
  • CAS score

Example Documentation

52F with Graves’ disease (TRAb 8.2 IU/L, suppressed TSH <0.01 μIU/mL, diffusely enlarged thyroid on ultrasound). No thyroid storm. CAS score 2/7. Plan: Methimazole 10mg daily.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Hyperthyroidism, follow-up.
Good Documentation Example
Graves’ disease (TRAb+, no goiter on palpation), stable without crisis. TSH 0.02 μIU/mL, free T4 2.8 ng/dL.
Explanation
The good example specifies TRAb positivity and thyroid function, supporting the diagnosis.
