ICD-10-CM Billable Code

H18.799

Other corneal deformities, unspecified eye

Clinical Classification Guidelines

Medical Intelligence & Overview

Corneal deformities refer to abnormalities or irregularities in the shape of the cornea, the clear, dome-shaped surface that covers the front of the eye. These deformities can affect vision and may be caused by various factors, leading to a condition classified under ICD-10 code H18.799 when the specific cause is unknown or not categorized elsewhere. Recognizing and understanding these deformities is essential for appropriate management and treatment planning, often involving eye specialists or ophthalmologists.

Causes & Symptoms

Clinical Causes: Congenital anomalies present at birth Scar formation from previous injuries or infections Keratoconus, a progressive thinning and bulging of the cornea Corneal dystrophies, inherited disorders causing corneal tissue abnormalities Previous eye surgeries or trauma leading to structural changes Prolonged contact lens wear causing corneal reshaping Inflammatory eye conditions that damage corneal tissue Degenerative conditions affecting corneal integrity

Key Symptoms: Blurry or distorted vision Increased sensitivity to light or glare Seeing halos around lights Difficulty with night vision Eye discomfort or irritation Redness or swelling around the eye On examination, irregular corneal shape with possible scarring

Diagnostic & Treatment

Diagnosis Path: Visual acuity testing to assess clarity of vision Slit-lamp examination to observe corneal shape and surface abnormalities Corneal topography or tomography for detailed mapping of corneal surface Pachymetry to measure corneal thickness Additional imagings or tests as needed based on suspected underlying cause

Treatment Protocols: Corrective lenses, such as glasses or rigid contact lenses, to improve vision Specialized contact lenses like scleral lenses for irregular corneas Medical management of underlying inflammatory or infectious causes Corneal cross-linking procedures to strengthen corneal tissue in cases like keratoconus Surgical options such as corneal transplant or keratoplasty for severe cases Emerging therapies including custom-made contact lenses and advanced surgical techniques

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
