New diagnosis codes can help prove medical necessity In the June 2006 issue of Ophthalmology Coding Alert we introduced you to the new ICD-9 codes that take effect Oct. 1. Now's the time to make sure your superbill, your providers, your coding and billing staff, and your electronic system are all updated with the new codes. Here's a quick review of what you need to add: • 377.43--Optic nerve hypoplasia • 379.60--Inflammation (infection) of postprocedural bleb, unspecified • 379.61--Inflammation (infection) of postprocedural bleb, stage 1 • 379.62--Inflammation (infection) of postprocedural bleb, stage 2 • 379.63--Inflammation (infection) of postprocedural bleb, stage 3.
