D36.0Benign neoplasm of lymph nodes

D36.0 is the ICD-10-CM diagnosis code for benign neoplasm of lymph nodes. It belongs to category D36 (benign neoplasm of other and unspecified sites), block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within D36 (benign neoplasm of other and unspecified sites), D36.0 is specifically for benign neoplasm of lymph nodes. Related codes cover neoplasm of peripheral nerves and autonomic nervous system (D36.1), neoplasm of other specified sites (D36.7) and neoplasm, unspecified site (D36.9).

Don't report D36.0 together with the conditions in its Excludes1 note: lymphangioma (D18.1).

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 229.0 (benign neoplasm of lymph nodes).
