ICD-10 code for left xanthelasma

The ICD-10-CM code for left xanthelasma is H02.66 (Xanthelasma of left eye, unspecified eyelid). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H02.66.

Within H02.6, choose H02.66 (left eye, unspecified eyelid) only when documentation doesn't support a more specific option: unspecified eye, unspecified eyelid (H02.60), right upper eyelid (H02.61), right lower eyelid (H02.62), right eye, unspecified eyelid (H02.63), left upper eyelid (H02.64) and left lower eyelid (H02.65).

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 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
