About I89.8

I89.8 is the ICD-10-CM diagnosis code for other specified noninfective disorders of lymphatic vessels and lymph nodes. It belongs to category I89 (other noninfective disorders of lymphatic vessels and lymph nodes), block I80-I89 (diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within I89, choose I89.8 (Other specified noninfective disorders of lymphatic vessels and lymph nodes) only when documentation doesn't support a more specific option: lymphedema, not elsewhere classified (I89.0), lymphangitis (I89.1) and noninfective disorder of lymphatic vessels and lymph nodes, unspecified (I89.9).

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.

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 457.8 (other noninfectious disorders of lymphatic channels).
