About H53.461

H53.461 is the ICD-10-CM diagnosis code for Homonymous bilateral field defects, right side. It belongs to category H53 (visual disturbances), block H53-H54 (visual disturbances and blindness) 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 H53.46 (Homonymous bilateral field defects), H53.461 is specifically for Homonymous bilateral field defects, right side. Related codes cover left side (H53.462) and unspecified side (H53.469).

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.

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 368.46 (Homonymous bilateral field defects).
