H18.7
Other and unspecified corneal deformities
Clinical Classification Guidelines
Excludes Type 1
- congenital malformations of cornea (Q13.3-Q13.4)
Medical Intelligence & Overview
Corneal deformities refer to abnormal shapes or structures of the cornea, which is the clear, dome-shaped surface that covers the front of the eye. The ICD-10 code H18.7 categorizes a range of corneal deformities that do not fit into more specific diagnoses, including various unusual or unidentified changes to the corneal shape. These deformities can impact vision and eye health, depending on their severity and underlying cause. Recognizing these conditions is vital for ophthalmologists to determine appropriate management and treatment strategies.
Causes & Symptoms
Clinical Causes: Genetic factors or inherited conditions affecting corneal development Previous eye injuries or trauma leading to deformity Corneal infections that cause scarring or structural changes Degenerative diseases or progressive thinning of the cornea Post-surgical changes, especially after eye surgeries like keratoplasty or refractive procedures Unclear or idiopathic causes where no specific reason is identified
Key Symptoms: Blurry or distorted vision Sensitivity to light (photophobia) Blurred or double vision in some cases Visual discomfort or eye strain Possible corneal scarring or irregularities visible upon examination
Diagnostic & Treatment
Diagnosis Path: Visual acuity tests to assess the clarity of vision Slit-lamp examination to observe corneal shape and any irregularities Corneal topography or tomography to map the surface of the cornea precisely Pachymetry to measure corneal thickness Assessment of refraction to understand visual distortions
Treatment Protocols: Corrective lenses such as glasses or contact lenses designed for irregular corneas Specialized contact lenses like scleral or rigid gas-permeable lenses to improve visual acuity Surgical interventions, including corneal transplantation (keratoplasty), in severe cases Corneal collagen cross-linking to strengthen the corneal structure (when applicable) Regular monitoring to track progression and adjust treatment as needed

Billing Guidance
Is H18.7 a billable ICD-10 code?
Yes, H18.7 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report H18.7?
Clinical documentation must specify the nature of Other and unspecified corneal deformities and any associated comorbidities for accurate reporting.
