About coding Ixodiasis NEC
The ICD-10-CM code for Ixodiasis NEC is B88.8 (Other specified infestations).
Within B88, choose B88.8 (Other specified infestations) only when documentation doesn't support a more specific option: other acariasis (B88.0), Tungiasis [sandflea infestation] (B88.1), other arthropod infestations (B88.2), external hirudiniasis (B88.3) and infestation, unspecified (B88.9).
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.
