About H40.04
H40.04 is the ICD-10-CM diagnosis code for steroid responder. It belongs to category H40 (glaucoma), block H40-H42 (glaucoma) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.
Within H40.0 (glaucoma suspect), H40.04 is specifically for steroid responder. Related codes cover Preglaucoma, unspecified (H40.00), open angle with borderline findings, low risk (H40.01), open angle with borderline findings, high risk (H40.02), anatomical narrow angle (H40.03), ocular hypertension (H40.05) and primary angle closure without glaucoma damage (H40.06).
To report this condition, pick the subcode that matches the documentation: H40.041 (right eye), H40.042 (left eye), H40.043 (bilateral) and H40.049 (unspecified eye).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
