About H01.129

H01.129 is the ICD-10-CM diagnosis code for Discoid lupus erythematosus of unspecified eye, unspecified eyelid. It belongs to category H01 (other inflammation of eyelid), block H00-H05 (disorders of eyelid, lacrimal system and orbit) 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 H01.12, choose H01.129 (unspecified eye, unspecified eyelid) only when documentation doesn't support a more specific option: right upper eyelid (H01.121), right lower eyelid (H01.122), right eye, unspecified eyelid (H01.123), left upper eyelid (H01.124), left lower eyelid (H01.125) and left eye, unspecified eyelid (H01.126).

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.

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 373.34 (Discoid lupus erythematosus of eyelid).
