Compare key differences between these codes to ensure accurate selection

CodeDescriptionWhen to UseKey Documentation
E04.9Nontoxic goiter, unspecifiedUse when the type of goiter is not specified in the documentation.
  • Physical exam findings of thyroid enlargement without specific type documented
E04.2Nontoxic multinodular goiterUse when multiple nodules are confirmed by imaging.
  • Ultrasound report showing multiple nodules

Clinical Decision Support

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

Decision Criteria

documentation Criteria

  • Documentation lacks specific type of goiter.

Applicable To

  • Simple goiter
  • Thyroid enlargement NOS

Excludes

  • Toxic goiter (E05.-)

Clinical Validation Requirements

  • Physical exam findings of thyroid enlargement without specific type documented

Code-Specific Risks

  • Risk of under-coding if specific type is not documented.

Coding Notes

  • Ensure documentation specifies 'nontoxic' to avoid misclassification.

Ancillary Codes

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

Dysphagia, unspecified

R13.10
Use if patient presents with swallowing difficulties due to goiter.

Differential Codes

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

Nontoxic multinodular goiter

E04.2
Use when ultrasound confirms multiple nodules.

Nontoxic goiter, unspecified

E04.9
Use when type of goiter is not specified.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Enlarged Thyroid to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E04.9.

Impact

Clinical: Leads to generic treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims or reduced reimbursement.

Mitigation Strategy

Use structured templates for documentation, Ensure all diagnostic tests are recorded

Impact

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

Mitigation Strategy

Ensure documentation specifies 'nodule' or 'goiter' explicitly.

Impact

Inadequate documentation of thyroid enlargement specifics.

Mitigation Strategy

Implement thorough documentation practices.

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.

Documentation Templates for Enlarged Thyroid

Use these documentation templates to ensure complete and accurate documentation for Enlarged Thyroid. These templates include all required elements for proper coding and billing.

Patient with thyroid enlargement

Specialty: Endocrinology

Required Elements

  • Patient symptoms
  • Physical exam findings
  • Ultrasound results
  • Thyroid function tests

Example Documentation

**Subjective:** Patient reports neck swelling and difficulty swallowing. **Objective:** Thyroid palpable, 3cm enlargement noted. **Assessment:** Nontoxic multinodular goiter confirmed by ultrasound.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Thyroid enlarged, follow up in 6 months.
Good Documentation Example
3cm right thyroid lobe nodule, TI-RADS 3, TSH 2.1 mIU/L → E04.1.
Explanation
The good example provides specific measurements and diagnostic criteria, allowing for accurate coding.
