0.000What This Code Means
A type of cancer called Kaposi's sarcoma that develops specifically in the right lung.
Coding Tips
- •This code requires documentation of right lung involvement; ensure laterality is clearly stated in the medical record.
- •Link this diagnosis with any immunosuppression or HIV status codes for complete clinical picture.
Clinical Significance
Kaposi sarcoma specifically documented in the right lung represents the highest specificity code for right-sided pulmonary involvement. Laterality-specific coding supports more accurate disease tracking and demonstrates documentation quality, which is increasingly important in risk adjustment audits.
Documentation Requirements
- ✓Imaging confirming right lung involvement specifically
- ✓Biopsy or cytology confirming Kaposi sarcoma histology
- ✓Extent of right lung involvement (localized versus diffuse)
- ✓Associated respiratory symptoms and oxygen requirements
- ✓Human Immunodeficiency Virus status with CD4 count and viral load
Commonly Confused Codes
C46.50 (Kaposi sarcoma of unspecified lung) — use only when laterality cannot be determinedC46.52 (Kaposi sarcoma of left lung) — opposite lateralityC34.11 (Malignant neoplasm of upper lobe, right bronchus or lung) — primary lung carcinoma, not Kaposi sarcomaC78.01 (Secondary malignant neoplasm of right lung) — metastatic disease, not Kaposi sarcoma
