About H33.8
H33.8 is the ICD-10-CM diagnosis code for other retinal detachments. It belongs to category H33 (retinal detachments and breaks), block H30-H36 (disorders of choroid and retina) and chapter 7 (diseases of the eye and adnexa). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within H33, choose H33.8 (Other retinal detachments) only when documentation doesn't support a more specific option: retinal detachment with retinal break (H33.0), retinoschisis and retinal cysts (H33.1), serous retinal detachment (H33.2), retinal breaks without detachment (H33.3) and traction detachment of retina (H33.4).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), in MDC 02 (Diseases and Disorders of the Eye), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 361.89 (other forms of retinal detachment).
