Code Description

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

Key Diagnostic Point:

D23 encompasses a variety of benign skin neoplasms that do not fall under more specific categories. These include lesions such as dermatofibromas, seborrheic keratosis, and other non-malignant tumors of the skin. These neoplasms are typically characterized by their slow growth, well-defined borders, and lack of invasive behavior. Clinically, they may present as asymptomatic or cause mild discomfort, depending on their location and size. Diagnosis is often made through clinical examination, and in some cases, a biopsy may be performed to confirm the benign nature of the lesion. Management usually involves monitoring, and surgical excision may be indicated if the neoplasm is symptomatic or for cosmetic reasons. Follow-up care is generally minimal unless there are changes in the lesion's appearance or symptoms arise, which may warrant further evaluation.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of benign neoplasms included under this code
  • Need for accurate documentation of lesion characteristics
  • Differentiation from malignant skin conditions
  • Potential for overlapping codes with other skin conditions

Audit Risk Factors

  • Inadequate documentation of lesion characteristics
  • Misclassification of benign neoplasms as malignant
  • Failure to document the reason for excision
  • Inconsistent follow-up documentation

Specialty Focus

Medical Specialties

Dermatology

Documentation Requirements

Detailed descriptions of the lesion, including size, location, and characteristics.

Common Clinical Scenarios

Evaluation of asymptomatic skin lesions, management of symptomatic benign neoplasms.

Billing Considerations

Ensure clear differentiation between benign and malignant lesions to avoid coding errors.

Oncology

Documentation Requirements

Comprehensive history of the lesion, including any previous treatments or biopsies.

Common Clinical Scenarios

Follow-up of previously diagnosed benign neoplasms, assessment of changes in lesion appearance.

Billing Considerations

Documentation must clearly indicate the benign nature of the neoplasm to prevent misclassification.

Coding Guidelines

Inclusion Criteria

Use D23 When
  • According to official coding guidelines, D23 should be used when a benign neoplasm of the skin is diagnosed and should not be used for malignant neoplasms or neoplasms of uncertain behavior
  • Coders must ensure that the documentation supports the diagnosis and that the neoplasm is indeed benign

Exclusion Criteria

Do NOT use D23 When
No specific exclusions found.

Excision, benign skin lesion

Clinical Scenario

Used when a benign neoplasm is excised for symptomatic relief or cosmetic reasons.

Documentation Requirements

Document the size, location, and reason for excision.

Specialty Considerations

Dermatologists should ensure that the excised lesion is clearly documented as benign.

ICD-10 Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of benign skin neoplasms, improving the accuracy of data collection and reimbursement processes. D23 provides a clear categorization for various benign lesions that were previously grouped under broader codes in ICD-9.
