Code Description

ICD-10 D03.11 is a billable code used to indicate a diagnosis of melanoma in situ of right eyelid, including canthus.

Key Diagnostic Point:

Melanoma in situ of the right eyelid, including the canthus, is a localized form of skin cancer characterized by the presence of atypical melanocytes confined to the epidermis. This condition is considered a precursor to invasive melanoma and is typically asymptomatic in its early stages. Clinically, it may present as a pigmented lesion or a non-pigmented area that may be mistaken for other skin conditions. The eyelid, being a delicate area, requires careful monitoring and management due to the potential for cosmetic and functional impairment. Diagnosis is usually confirmed through a biopsy, which reveals atypical melanocytes without invasion into the dermis. Surveillance protocols for patients diagnosed with melanoma in situ include regular dermatological examinations and patient education on self-monitoring for changes in skin lesions. The risk of progression to invasive melanoma is present, particularly if the lesion is not adequately treated, making early intervention crucial.

  • Potential for progression to invasive melanoma

Audit Risk Factors

  • Inadequate documentation of biopsy results
  • Failure to specify the exact location of the lesion
  • Misclassification of the lesion type
  • Lack of follow-up documentation

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of melanoma in situ, improving the accuracy of data collection and treatment tracking. This specificity aids in better patient management and research outcomes.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of melanoma in situ, improving the accuracy of data collection and treatment tracking. This specificity aids in better patient management and research outcomes.

Reimbursement & Billing Impact
