About coding retina change
The ICD-10-CM code for retina change is H35.9 (Unspecified retinal disorder). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on H35.9.
Within H35, choose H35.9 (Unspecified retinal disorder) only when documentation doesn't support a more specific option: background retinopathy and retinal vascular changes (H35.0), retinopathy of prematurity (H35.1), other non-diabetic proliferative retinopathy (H35.2), degeneration of macula and posterior pole (H35.3), peripheral retinal degeneration (H35.4), hereditary retinal dystrophy (H35.5), retinal hemorrhage (H35.6), separation of retinal layers (H35.7) and 1 more.
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.
