- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
H59.092 is a billable ICD-10-CM diagnosis code for other disorders of the left eye following cataract surgery. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 919 through 921. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 34 closely related codes. Coders also document this condition as disorder of left eye following cataract surgery. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Postprocedural or postoperative eye complication.

Cataract
A cataract is a clouding of the clear lens inside your eye. This cloudiness blocks light from reaching the back of the eye, making it harder to see clearly. A cataract can affect one or both eyes, but it doesn't spread from one eye to the other.

What MS-DRG does H59.092 group to?

Is H59.092 a CC or MCC?
CMS lists H59.092 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 34 closely related codes in its exclusion list.

Not as a rule. The Excludes1 note at H59, which applies to H59.092, lists "mechanical complication of intraocular lens (T85.2)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
