ICD-10 Code H40.049 – Steroid responder, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.049 – Steroid responder, unspecified eye
What it is
This code identifies an eye that responds abnormally to steroid use, usually with increased intraocular pressure. Use it when documentation states steroid responder and does not specify which eye.
Clinical signs
Clinical findings often include elevated intraocular pressure after steroid exposure, sometimes without early symptoms. Clinical features vary; refer to documentation.
When to use this code
Use H40.049 when the provider documents steroid response in an unspecified eye and links it to steroid use. It is appropriate when the record does not identify right, left, or bilateral eye involvement. Check documentation if glaucoma or another eye disorder is also recorded.
Do not use for
Do not use this code for glaucoma without documented steroid response. Do not assume the eye laterality; use a more specific code if the record identifies the affected eye.
Coding tip
Confirm both steroid exposure and eye laterality in the note before assigning the code.
