ICD-10 Code for Keratoglobus
The ICD-10-CM code for keratoglobus is H18.79 — Other corneal deformities. This is the code the Alphabetic Index gives for keratoglobus with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
H18.79 cannot be submitted on a claim. It is a header code, so a more specific code from the list below is required.
