ICD-10 code for glands swelling

The ICD-10-CM code for glands swelling is R59.9 (Enlarged lymph nodes, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R59.9.

Within R59, choose R59.9 (unspecified) only when documentation doesn't support a more specific option: localized enlarged lymph nodes (R59.0) and generalized enlarged lymph nodes (R59.1).

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.
