About coding spleen abscess
The ICD-10-CM code for spleen abscess is D73.3 (Abscess of spleen). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on D73.3.
Within D73 (diseases of spleen), D73.3 is specifically for abscess of spleen. Related codes cover Hyposplenism (D73.0), Hypersplenism (D73.1), chronic congestive splenomegaly (D73.2), cyst of spleen (D73.4), infarction of spleen (D73.5), other diseases of spleen (D73.8) and disease of spleen, unspecified (D73.9).
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 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.
