ICD-10-CM Code H11.001
Unspecified pterygium of right eye
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.H11.001 is a billable ICD code used to specify a diagnosis of unspecified pterygium of right eye. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code H110 is used to code Pterygium (conjunctiva)
Pterygium (Surfer's Eye) most often refers to a benign growth of the conjunctiva. A pterygium commonly grows from the nasal side of the conjunctiva. It is usually present in the palpebral fissure. It is associated with and thought to be caused by ultraviolet-light exposure (e.g., sunlight), low humidity, and dust. The predominance of pterygia on the nasal side is possibly a result of the sun's rays passing laterally through the cornea, where it undergoes refraction and becomes focused on the limbic area. Sunlight passes unobstructed from the lateral side of the eye, focusing on the medial limbus after passing through the cornea. On the contralateral (medial) side, however, the shadow of the nose medially reduces the intensity of sunlight focused on the lateral/temporal limbus.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code H11.001 and a single ICD9 code, 372.40 is an approximate match for comparison and conversion purposes.
