ICD-10 code for Lymphoreticulosis

The ICD-10-CM code for Lymphoreticulosis is A28.1 (Cat-scratch disease).

Within A28 (other zoonotic bacterial diseases, not elsewhere classified), A28.1 is specifically for Cat-scratch disease. Related codes cover Pasteurellosis (A28.0), Extraintestinal yersiniosis (A28.2), other specified zoonotic bacterial diseases, not elsewhere classified (A28.8) and zoonotic bacterial disease, unspecified (A28.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 814 (Reticuloendothelial and Immunity Disorders with MCC, relative weight 2.0729), DRG 815 (Reticuloendothelial and Immunity Disorders with CC, relative weight 1.0444) and DRG 816 (Reticuloendothelial and Immunity Disorders without CC/MCC, relative weight 0.7381), in MDC 16 (Diseases and Disorders of the Blood and Blood Forming Organs and Immunological Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
