ICD-10 code for axillary gland lymph infection

The ICD-10-CM code for axillary gland lymph infection is L04.2 (Acute lymphadenitis of upper limb).

Within L04 (acute lymphadenitis), L04.2 is specifically for acute lymphadenitis of upper limb. Related codes cover of face, head and neck (L04.0), of trunk (L04.1), of lower limb (L04.3), of other sites (L04.8) and unspecified (L04.9).

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 791 (Prematurity with Major Problems, relative weight 4.1075), DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), 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 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and 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.
