ICD-10 code for degenerative malignant myopia

The ICD-10-CM code for degenerative malignant myopia is H44.20 (Degenerative myopia, unspecified eye). The official index lists 8 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H44.20.

Within H44.2, choose H44.20 (unspecified eye) only when documentation doesn't support a more specific option: right eye (H44.21), left eye (H44.22), bilateral (H44.23), with choroidal neovascularization (H44.2A), with macular hole (H44.2B), with retinal detachment (H44.2C), with foveoschisis (H44.2D) and with other maculopathy (H44.2E).

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.
