0.000What This Code Means
A cancerous tumor of the left ciliary body, the muscular structure inside the eye that adjusts the lens and produces eye fluid.
Coding Tips
- •Verify left eye is documented; ensure no confusion with right eye coding
- •Ciliary body malignancies may present with secondary glaucoma; document any associated conditions
Clinical Significance
Left ciliary body malignancy carries the same urgent clinical implications as right-sided tumors, with identical treatment considerations and metastatic risk profile. Accurate laterality coding prevents wrong-site surgical errors and ensures proper follow-up surveillance protocols are applied to the correct eye.
Documentation Requirements
- ✓Clinical or pathological confirmation of ciliary body malignancy
- ✓Explicit documentation of left eye involvement
- ✓Tumor measurements and relationship to adjacent structures
- ✓Assessment of intraocular pressure and lens status
- ✓Systemic metastatic screening documentation
