Complete code families applicable to Axillary Lymphadenopathy

R59Primary Range

Enlarged lymph nodes

This range includes codes for localized, generalized, and unspecified lymphadenopathy, which are applicable to axillary lymphadenopathy.

Acute lymphadenitis

This range is relevant when the lymphadenopathy is due to an acute infection.

Nonspecific lymphadenitis

This range is relevant for chronic lymphadenitis, which may present similarly to lymphadenopathy.

Code Comparison: When to Use Each Code

Compare key differences between these codes to ensure accurate selection

CodeDescriptionWhen to UseKey Documentation
R59.0Localized enlarged lymph nodesUse when lymphadenopathy is localized to the axillary region and specific laterality is documented.
  • Documentation of laterality (left/right)
  • Imaging findings such as cortical thickening >3mm
R59.9Enlarged lymph nodes, unspecifiedUse only when documentation does not specify the location or laterality of lymphadenopathy.
  • Lack of specific documentation regarding localization or laterality

Clinical Decision Support

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

Key Information: ICD-10 code for axillary lymphadenopathy

Essential facts and insights about Axillary Lymphadenopathy

The ICD-10 code for localized axillary lymphadenopathy is R59.0, used when the condition is confined to the axillary region with documented laterality.

Primary ICD-10-CM Codes for axillary lymphadenopathy

Localized enlarged lymph nodes
Billable Code

Decision Criteria

clinical Criteria

  • Presence of localized swelling in the axillary region with imaging confirmation.

documentation Criteria

  • Specific mention of 'localized axillary lymphadenopathy' with laterality.

Applicable To

  • Localized axillary lymphadenopathy

Excludes

Clinical Validation Requirements

  • Documentation of laterality (left/right)
  • Imaging findings such as cortical thickening >3mm

Code-Specific Risks

  • Confusion with lymphadenitis codes
  • Missing laterality documentation

Coding Notes

  • Ensure documentation specifies 'localized' and 'axillary' to avoid using unspecified codes.

Ancillary Codes

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

Encounter for immunization

Z23
Use when lymphadenopathy is related to recent vaccination.

Differential Codes

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

Generalized enlarged lymph nodes

R59.1
Use when lymphadenopathy is not confined to a specific region.

Localized enlarged lymph nodes

R59.0
Use when specific localization is documented.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Axillary Lymphadenopathy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R59.0.

Impact

Clinical: Leads to inaccurate clinical records., Regulatory: May trigger audits due to unspecified coding., Financial: Potential for denied claims.

Mitigation Strategy

Review documentation for specific details before coding., Query provider if documentation is unclear.

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: May result in compliance issues during audits., Data Quality: Affects the accuracy of clinical data.

Mitigation Strategy

Ensure documentation specifies 'lymphadenopathy' and not 'lymphadenitis'.

Impact

Using R59.9 without sufficient documentation.

Mitigation Strategy

Ensure documentation specifies location and laterality.

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 Axillary Lymphadenopathy

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

Localized Axillary Lymphadenopathy

Specialty: Radiology

Required Elements

  • Location and laterality
  • Size and characteristics of lymph nodes
  • Imaging findings

Example Documentation

Ultrasound shows a 2.5 cm node in the left axilla with cortical thickening of 4 mm.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Swollen nodes in armpit.
Good Documentation Example
2.5 cm firm, fixed node in left axilla level II, cortical thickness 4 mm on ultrasound.
Explanation
The good example provides specific location, size, and imaging details necessary for accurate coding.
