E10.3 vs H36
E10.3 (Type 1 diabetes mellitus with ophthalmic complications) compared with H36 (Retinal disorders in diseases classified elsewhere), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. H36 carries an Excludes1 note covering E10.3: “diabetic retinopathy (E08.3-, E09.3-, E10.3-, E11.3-, E13.3-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
