0.000What This Code Means
Cancer of the conjunctiva, the clear membrane covering the white part of the right eye.
Coding Tips
- •The fifth character specifies laterality; ensure correct eye is documented (right vs. left)
- •Obtain ophthalmology reports confirming conjunctival involvement and histological type
Clinical Significance
Right conjunctival malignancy requires laterality-specific coding for accurate clinical tracking and treatment planning. Conjunctival cancers, though uncommon, can be vision-threatening and may indicate systemic conditions such as immunosuppression (especially with squamous cell carcinoma related to human immunodeficiency virus) or genetic predisposition.
Documentation Requirements
- ✓Pathology confirming malignancy with specific histological type
- ✓Documentation clearly stating right eye involvement
- ✓Ophthalmologic examination with detailed description of tumor location on the conjunctiva
- ✓Tumor dimensions, depth of invasion, and clinical stage
- ✓Any associated conditions (human immunodeficiency virus status, immunosuppression)
Commonly Confused Codes
C69.02 — Left conjunctiva: verify laterality carefully; documentation sometimes references the image side rather than patient sideC69.00 — Unspecified conjunctiva: use C69.01 when right eye is documentedC69.11 — Right cornea: conjunctiva covers the white of the eye; cornea is the clear front surface — different structuresD09.21 — Carcinoma in situ of right conjunctiva: invasive versus in situ distinction is critical
