About coding eyelid dermatitis
The ICD-10-CM code for eyelid dermatitis is H01.9 (Unspecified inflammation of eyelid). The official index lists 18 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H01.9.
Within H01, choose H01.9 (Unspecified inflammation of eyelid) only when documentation doesn't support a more specific option: blepharitis (H01.0), noninfectious dermatoses of eyelid (H01.1) and other specified inflammations of eyelid (H01.8).
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.
