About H27.8

H27.8 is the ICD-10-CM diagnosis code for other specified disorders of lens. It belongs to category H27 (other disorders of lens), block H25-H28 (disorders of lens) 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 H27, choose H27.8 (Other specified disorders of lens) only when documentation doesn't support a more specific option: aphakia (H27.0), dislocation of lens (H27.1) and unspecified disorder of lens (H27.9).

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 379.39 (other disorders of lens).
