Marginal corneal ulcer, left eye
ICD-10 H16.042 is a billable code used to indicate a diagnosis of marginal corneal ulcer, left eye.
Marginal corneal ulcer of the left eye is characterized by localized inflammation and ulceration at the edge of the cornea, often resulting from infectious or non-infectious causes. Clinically, patients may present with symptoms such as redness, pain, photophobia, and decreased vision. The anatomy involved includes the cornea, which is the transparent front part of the eye, and its marginal zone where the cornea meets the sclera. Disease progression can lead to complications such as corneal scarring or perforation if left untreated. Diagnostic considerations include a thorough eye examination, slit-lamp biomicroscopy, and possibly cultures or staining to identify infectious agents. The condition may be associated with underlying systemic diseases, contact lens wear, or environmental factors, necessitating a comprehensive evaluation to determine the etiology and appropriate management.

H16.042 specifically covers marginal corneal ulcers of the left eye, which may arise from infectious agents, trauma, or underlying systemic conditions. It is essential to differentiate it from other corneal disorders such as central corneal ulcers or keratitis.
H16.042 should be used when the clinical presentation specifically indicates a marginal corneal ulcer in the left eye, distinguishing it from right eye conditions or other types of corneal ulcers.
Documentation should include a detailed clinical examination, patient history, diagnostic test results, and treatment plans. Specific notes on symptoms, visual acuity, and any interventions performed are crucial for supporting the use of this code.
