H10.522
BillableAngular blepharoconjunctivitis, left eye
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Angular blepharoconjunctivitis is an inflammation of the eyelid and conjunctiva (the clear membrane covering the white part of the eye) that typically occurs at the angles or corners of the eye, specifically affecting the left eye in this case. This condition often causes redness, irritation, and discharge in the affected eye.
Coding Tips
- •Ensure laterality is documented in the medical record as 'left eye' to support the use of the fifth character '2' in this code
- •Verify that the diagnosis specifies angular blepharoconjunctivitis rather than other forms of conjunctivitis, as different subtypes have distinct codes (H10.521 for right eye, H10.523 for bilateral)
