What This Code Means
H40.5 is the ICD-10-CM diagnosis code for glaucoma secondary to other eye disorders. H40.5 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering glaucoma (h40-h42).
Header codes like H40.5 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H40.5 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
