Code Description

ICD-10 D04.72 is a billable code used to indicate a diagnosis of carcinoma in situ of skin of left lower limb, including hip.

Key Diagnostic Point:

Carcinoma in situ (CIS) of the skin represents a localized, non-invasive form of skin cancer where abnormal cells are present but have not invaded deeper tissues. Specifically, D04.72 refers to CIS located on the skin of the left lower limb, including the hip. This condition is characterized by atypical keratinocytes confined to the epidermis, with no evidence of invasion into the dermis. Commonly associated with sun exposure, CIS can manifest as various lesions, including actinic keratosis or squamous cell carcinoma in situ. Early detection and treatment are crucial to prevent progression to invasive cancer. Treatment options may include surgical excision, cryotherapy, or topical chemotherapy. Regular surveillance is essential to monitor for any changes in the lesions and to manage any potential progression effectively. Patients with a history of skin cancer or significant sun exposure should be particularly vigilant in their follow-up care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Specificity of the anatomical location (left lower limb, including hip)
  • Differentiation from other skin conditions
  • Need for precise documentation of lesion characteristics
  • Potential for progression to invasive carcinoma

Audit Risk Factors

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

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for greater specificity in coding skin conditions, including carcinoma in situ. D04.72 provides detailed information about the location and type of carcinoma, which is essential for treatment planning and epidemiological tracking.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding skin conditions, including carcinoma in situ. D04.72 provides detailed information about the location and type of carcinoma, which is essential for treatment planning and epidemiological tracking.

Frequently Asked Questions

What is carcinoma in situ?

Carcinoma in situ is a localized form of cancer where abnormal cells are present but have not invaded surrounding tissues. It is considered non-invasive and can often be treated effectively.
