Code Description

ICD-10 D23.5 is a billable code used to indicate a diagnosis of other benign neoplasm of skin of trunk.

Key Diagnostic Point:

D23.5 refers to other benign neoplasms of the skin located on the trunk, which includes the chest, abdomen, and back. These neoplasms can manifest as various types of skin lesions, such as dermatofibromas, lipomas, or other benign tumors that do not fit into more specific categories. Clinically, these lesions are typically asymptomatic and may be discovered incidentally during physical examinations. While benign, they can sometimes cause cosmetic concerns or discomfort depending on their size and location. Management often involves monitoring for changes in size or appearance, and surgical excision may be considered if the lesion becomes bothersome or if there is uncertainty regarding its nature. Follow-up care is generally minimal unless there are changes in the lesion that warrant further investigation. Accurate coding requires careful documentation of the lesion's characteristics, including size, location, and any symptoms reported by the patient.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of benign skin lesions that can be coded under this category
  • Need for precise documentation to differentiate from malignant lesions
  • Potential for overlapping symptoms with other skin conditions
  • Variability in clinical presentation and management approaches

Audit Risk Factors

  • Inadequate documentation of lesion characteristics
  • Misclassification of benign lesions as malignant
  • Failure to document the patient's symptoms or lack thereof
  • Inconsistent follow-up notes regarding lesion changes

Documentation Requirements

Document the size, location, and type of lesion excised.

Specialty Considerations

Dermatologists should ensure that the excision is justified based on clinical findings.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of benign skin lesions, improving the accuracy of data collection and reimbursement processes. D23.5 provides a clear classification for lesions that do not fall into more specific categories, enhancing the granularity of patient records.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of benign skin lesions, improving the accuracy of data collection and reimbursement processes. D23.5 provides a clear classification for lesions that do not fall into more specific categories, enhancing the granularity of patient records.

Reimbursement & Billing Impact

Frequently Asked Questions

What types of lesions are classified under D23.5?

D23.5 includes various benign skin lesions such as dermatofibromas, lipomas, and other non-cancerous tumors located on the trunk.

How should I document a benign skin lesion for coding purposes?

Documentation should include the lesion's size, shape, color, location, and any symptoms. It is also important to note any changes over time.
