CodeDescriptionWhen to UseKey Documentation
D17.9Benign lipomatous neoplasm, unspecifiedUse when angiolipoma is documented without site specificity.
  • Pathology report confirming mature adipocytes with capillary proliferation and fibrin thrombi
  • Imaging showing fat-density lesion with vascular components
D17.21Benign lipomatous neoplasm of skin and subcutaneous tissue of right armUse when angiolipoma is documented on the right arm.
  • Pathology report confirming mature adipocytes with capillary proliferation and fibrin thrombi
  • Imaging showing fat-density lesion with vascular components

Clinical Decision Support

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

Billable Code

Decision Criteria

clinical Criteria

  • Presence of mature adipocytes with vascular proliferation and fibrin thrombi.

documentation Criteria

  • Specific mention of 'angiolipoma' in clinical notes.

Applicable To

  • Angiolipoma

Excludes

  • Angiomyolipoma
  • Hemangioma

Clinical Validation Requirements

  • Pathology report confirming mature adipocytes with capillary proliferation and fibrin thrombi
  • Imaging showing fat-density lesion with vascular components

Code-Specific Risks

  • Risk of misclassification if vascular components are not documented.

Coding Notes

  • Ensure documentation specifies 'angiolipoma' and includes vascular components.

Differential Codes

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

Benign neoplasm of kidney

D30.0
Presence of smooth muscle components, typically in angiomyolipoma.

Hemangioma

D18.0
Pure vascular lesion without adipose tissue.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Angiolipoma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D17.9.

Impact

Clinical: Misrepresentation of the condition, Regulatory: Non-compliance with coding standards, Financial: Potential for incorrect billing

Mitigation Strategy

Educate providers on the importance of specificity, Implement checklists for documentation

Impact

Reimbursement: Potential underpayment due to incorrect code usage., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Query provider for confirmation of vascular components.

Impact

Using D17.9 without site specificity can trigger audits.

Mitigation Strategy

Ensure documentation includes specific site information.

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 Angiolipoma, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Angiolipoma

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

Excision of subcutaneous angiolipoma

Specialty: Surgery

Required Elements

  • Pre-operative diagnosis
  • Operative findings
  • Pathology confirmation

Example Documentation

Pre-op: 3 cm firm, mobile mass in left forearm subcutaneous tissue. MRI shows fat-density lesion with vascular components. Procedure: Excision of left forearm subcutaneous mass. Pathology: Angiolipoma with fibrin thrombi (see report #123). Post-op Diagnosis: Angiolipoma, left forearm (D17.22).

Examples: Poor vs. Good Documentation

Poor Documentation Example
Fatty mass excised from back.
Good Documentation Example
2.5 cm subcutaneous angiolipoma excised from right upper back (D17.1), pathology confirms mature adipose tissue with vascular proliferation and fibrin thrombi.
Explanation
The good example specifies the type of lipoma, location, and includes pathology confirmation.
