About H44.2C2

H44.2C2 is the ICD-10-CM diagnosis code for degenerative myopia with retinal detachment, left eye. It belongs to category H44 (disorders of globe), 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 H44.2C (degenerative myopia with retinal detachment), H44.2C2 is specifically for degenerative myopia with retinal detachment, left eye. Related codes cover right eye (H44.2C1), bilateral (H44.2C3) and unspecified eye (H44.2C9).

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 was added in FY2018, effective October 1, 2017.

Before ICD-10, this condition was coded in ICD-9-CM as 360.21 (progressive high (degenerative) myopia) and 361.9 (unspecified retinal detachment).
