Clinical Classification Guidelines
Medical Intelligence & Overview
Simple chronic conjunctivitis is a persistent inflammation of the conjunctiva — the clear tissue covering the white part of the eye and the inside of the eyelids. When it affects only the right eye, it is classified under ICD-10 code H10.421. This condition often results in ongoing discomfort and redness, but it generally does not lead to more serious eye problems if properly managed. Recognizing the symptoms and understanding potential causes can help in seeking appropriate eye care and relief.
