About coding bleb
The ICD-10-CM code for bleb is R23.8 (Other skin changes). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R23.8.
Within R23, choose R23.8 (Other skin changes) only when documentation doesn't support a more specific option: Cyanosis (R23.0), Pallor (R23.1), Flushing (R23.2), spontaneous ecchymoses (R23.3), changes in skin texture (R23.4) and unspecified skin changes (R23.9).
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.
