About coding Hemianopia
The ICD-10-CM code for Hemianopia is H53.47 (Heteronymous bilateral field defects). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H53.47.
Within H53.4 (visual field defects), H53.47 is specifically for Heteronymous bilateral field defects. Related codes cover unspecified visual field defects (H53.40), Scotoma involving central area (H53.41), Scotoma of blind spot area (H53.42), Sector or arcuate defects (H53.43), other localized visual field defect (H53.45), Homonymous bilateral field defects (H53.46) and generalized contraction of visual field (H53.48).
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 123 (Neurological Eye Disorders, relative weight 0.822), 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.
