About coding immunoglobulin level elevated
The ICD-10-CM code for immunoglobulin level elevated is R76.89 (Other specified abnormal immunological findings in serum).
Within R76.8, choose R76.89 (Other specified abnormal immunological findings in serum) only when documentation doesn't support a more specific option: abnormal rheumatoid factor and anti-citrullinated protein antibody without rheumatoid arthritis (R76.81).
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 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.
