Summary
Independence Blue Cross updated MA07.046h to add three new ICD-10 diagnosis codes (H40.841, H40.842, H40.843) for corneal pachymetry coverage, effective 10/01/2025. This is a reissue with no substantive policy changes—only a diagnosis code update. Billing teams must ensure these glaucoma-related codes are recognized as medically necessary when submitted with CPT 76514.
Action Required
By October 1, 2025: Billing team must update internal coding reference materials and billing system rules to recognize ICD-10 codes H40.841, H40.842, and H40.843 as medically necessary diagnosis codes when submitted with CPT 76514 (corneal pachymetry). No system workflow changes are required. Ensure that claims with these diagnosis codes and CPT 76514 are not denied as lacking medical necessity. Communicate this update to providers performing corneal pachymetry to ensure proper diagnosis code selection on claims.
