About coding right blepharitis
The ICD-10-CM code for right blepharitis is H01.003 (Unspecified blepharitis right eye, unspecified eyelid). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H01.003.
Within H01.00, choose H01.003 (right eye, unspecified eyelid) only when documentation doesn't support a more specific option: right upper eyelid (H01.001), right lower eyelid (H01.002), left upper eyelid (H01.004), left lower eyelid (H01.005), left eye, unspecified eyelid (H01.006), unspecified eye, unspecified eyelid (H01.009), right eye, upper and lower eyelids (H01.00A) and left eye, upper and lower eyelids (H01.00B).
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.
