H18.712 is a billable ICD code used to specify a diagnosis of corneal ectasia, left eye. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code H187 is used to code Pellucid marginal degeneration

Pellucid marginal degeneration (PMD; keratotorus), is a degenerative corneal condition, often confused with keratoconus. It is typically characterized by a clear, bilateral thinning (ectasia) in the inferior and peripheral region of the cornea, although some cases affect only one eye. The cause of the disease remains unclear (idiopathic).

Specialty: Ophthalmology
ICD 9 Code: 371.48
