About H43.311

H43.311 is the ICD-10-CM diagnosis code for vitreous membranes and strands, right eye. It belongs to category H43 (disorders of vitreous body), block H43-H44 (disorders of vitreous body and globe) 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 H43.31 (vitreous membranes and strands), H43.311 is specifically for vitreous membranes and strands, right eye. Related codes cover left eye (H43.312), bilateral (H43.313) and unspecified eye (H43.319).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

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 379.25 (vitreous membranes and strands).
