Primary angle-closure glaucoma

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 5 more specific codes instead:

H40.20 Unspecified primary angle-closure glaucoma (also a header)
H40.21 Acute angle-closure glaucoma (also a header)
H40.22 Chronic angle-closure glaucoma (also a header)
H40.23 Intermittent angle-closure glaucoma (also a header)
H40.24 Residual stage of angle-closure glaucoma (also a header)

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

FY2012 Added to the draft code set draft Primary angle-closure glaucoma
