C69.90
BillableMalignant neoplasm of unspecified site of unspecified eye
HCC Category Mapping
What This Code Means
Cancer of the eye when the specific location within the eye cannot be determined and the side is not specified.
Coding Tips
- •Use only when specific site and laterality are unknown or unspecified
- •Query provider for more specific anatomical location and side
Clinical Significance
This doubly unspecified code (neither the anatomical site within the eye nor the laterality is known) represents the lowest level of documentation specificity for ocular malignancy. While it still captures the cancer diagnosis for risk adjustment, it signals significant documentation gaps that should be addressed through provider queries, as virtually all ocular malignancies can be localized through ophthalmologic examination.
Documentation Requirements
- ✓Confirmed diagnosis of malignancy of the eye
- ✓Documentation that more specific site and laterality information was sought but unavailable
- ✓Provider query documenting attempts to obtain specificity
- ✓Clinical staging if available
- ✓Referral to ophthalmology for definitive localization
