| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E04.1 | Nontoxic single thyroid nodule | Use when a single thyroid cyst is present without signs of hyperthyroidism. |

| E05.10 | Thyrotoxicosis with toxic single thyroid nodule without thyrotoxic crisis or storm | Use when a thyroid cyst is associated with hyperthyroidism. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for thyroid cyst
Decision Criteria
clinical Criteria
- Normal TSH and benign ultrasound findings
coding Criteria
- Absence of hyperthyroid symptoms
Applicable To
- Colloid cyst
- Thyroid cyst
Excludes
- Toxic thyroid nodule (E05.10)
Clinical Validation Requirements
- Normal TSH levels
- Ultrasound showing anechoic cystic nodule
- Benign FNA biopsy results
Code-Specific Risks
- Incorrectly coding as toxic when TSH is normal
Coding Notes
- Ensure documentation supports nontoxic status with normal thyroid function tests.
E05.10 - Thyrotoxicosis with toxic single thyroid nodule without thyrotoxic crisis or storm
Use when a thyroid cyst is associated with hyperthyroidism.
Applicable To
- Toxic thyroid nodule
Excludes
- Nontoxic thyroid nodule (E04.1)
Clinical Validation Requirements
- Suppressed TSH levels
- Elevated T3/T4 levels
- Symptoms of hyperthyroidism
Coding Notes
Document symptoms and lab results indicating hyperthyroidism.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Dysphagia
R13.1Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Thyroid Cyst to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E04.1.
Impact
Clinical: Misdiagnosis of thyroid condition., Regulatory: Non-compliance with coding guidelines., Financial: Potential claim denials.
Mitigation Strategy
Ensure lab results are reviewed and documented.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding standards., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Verify thyroid function tests and symptoms before coding.
Impact
Lack of documented thyroid function tests can lead to incorrect coding.
Mitigation Strategy
Implement a checklist for thyroid evaluations to ensure all necessary tests are documented.
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.
