H53.129Transient visual loss, unspecified eye

H53.129 is the ICD-10-CM diagnosis code for transient visual loss, unspecified eye. 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 H53.12, choose H53.129 (unspecified eye) only when documentation doesn't support a more specific option: right eye (H53.121), left eye (H53.122) and bilateral (H53.123).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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 is an unspecified code for which a more specific option (often laterality) exists, and the Medicare Code Editor flags it for review on inpatient claims.

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 368.12 (transient visual loss).
