Filamentary keratitis, bilateral
ICD-10 H16.123 is a billable code used to indicate a diagnosis of filamentary keratitis, bilateral.
Filamentary keratitis is a condition characterized by the presence of fine, thread-like strands of epithelial tissue that can adhere to the corneal surface, leading to irritation and inflammation. This condition typically affects both eyes (bilateral) and is often associated with underlying dry eye syndrome, exposure keratopathy, or other ocular surface disorders. The cornea, which is the transparent front part of the eye, becomes compromised due to the presence of these filaments, resulting in symptoms such as foreign body sensation, redness, tearing, and blurred vision. The conjunctiva and sclera may also exhibit signs of irritation due to the inflammatory response. Disease progression can lead to corneal scarring or ulceration if not managed appropriately. Diagnosis is primarily clinical, relying on slit-lamp examination to visualize the filaments and assess the extent of corneal involvement. Additional diagnostic tests may include tear break-up time and ocular surface staining to evaluate the overall health of the anterior segment. Early recognition and treatment are crucial to prevent complications and preserve visual function.

H16.123 specifically covers filamentary keratitis affecting both eyes, which may arise from various underlying conditions such as dry eye syndrome, exposure keratopathy, or chronic ocular surface disease. It is important to differentiate this from other forms of keratitis that may not involve filamentary strands.
H16.123 should be used when the clinician confirms filamentary keratitis affecting both eyes. If the condition is unilateral, the appropriate unilateral codes (H16.121 or H16.122) should be utilized. Accurate documentation of bilateral involvement is essential for correct coding.
Documentation should include a detailed clinical examination report, noting the presence of filaments on the cornea, symptoms reported by the patient, and any underlying conditions contributing to the keratitis. Treatment plans and follow-up assessments should also be documented to support the diagnosis.
