Code Description

ICD-10 D17.1 is a billable code used to indicate a diagnosis of benign lipomatous neoplasm of skin and subcutaneous tissue of trunk.

Key Diagnostic Point:

D17.1 refers to a benign lipomatous neoplasm, commonly known as a lipoma, located in the skin and subcutaneous tissue of the trunk. Lipomas are soft, movable lumps that are typically painless and composed of adipose (fat) tissue. They can vary in size and may be solitary or multiple. While lipomas are generally considered benign and do not have malignant potential, they can occasionally cause discomfort or cosmetic concerns, leading to surgical removal. Diagnosis is primarily clinical, often confirmed through imaging studies such as ultrasound or MRI if the lipoma is deep-seated. The management of lipomas usually involves observation unless they become symptomatic or the patient requests removal for aesthetic reasons. Regular surveillance is not typically required unless there are changes in size, shape, or symptoms, which may warrant further evaluation to rule out atypical presentations.

Code Complexity Analysis

Complexity Rating: Low

Low Complexity

Complexity Factors

  • Clear clinical definition of the condition
  • Well-established diagnostic criteria
  • Standard treatment protocols
  • Low likelihood of coding errors due to straightforward nature

Audit Risk Factors

  • Inconsistent documentation of size and location
  • Failure to specify if the lipoma is symptomatic
  • Lack of imaging documentation when necessary
  • Misclassification of lipomas as malignant neoplasms

Specialty Focus

Medical Specialties

Dermatology

Documentation Requirements

Detailed description of the lipoma, including size, location, and any symptoms.

Common Clinical Scenarios

Evaluation of a patient presenting with a new lipoma or follow-up of previously diagnosed lipomas.

Billing Considerations

Ensure that the documentation clearly states the benign nature of the neoplasm to avoid misclassification.

Surgery

Documentation Requirements

Operative reports should detail the procedure performed, including excision and pathology results.

Common Clinical Scenarios

Surgical removal of symptomatic or cosmetically concerning lipomas.

Billing Considerations

Document the rationale for surgical intervention, especially if the lipoma is asymptomatic.

Coding Guidelines

Inclusion Criteria

Use D17.1 When
  • According to ICD
  • 10 guidelines, D17
  • 1 should be used when the lipomatous neoplasm is confirmed as benign and located specifically in the trunk

Exclusion Criteria

Do NOT use D17.1 When
  • Exclusion criteria include any malignant transformation or atypical features that would necessitate a different code

Documentation Requirements

Operative report detailing the excision and pathology results.

Specialty Considerations

Ensure the procedure is documented as excision of a benign lesion.

Frequently Asked Questions

What is the typical treatment for a lipoma?

The typical treatment for a lipoma is surgical excision, especially if it is symptomatic or the patient desires removal for cosmetic reasons.
