ICD-10 code for lymphangitis

About coding lymphangitis
The ICD-10-CM code for lymphangitis is I89.1 (Lymphangitis). The official index lists 47 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I89.1.
Within I89 (other noninfective disorders of lymphatic vessels and lymph nodes), I89.1 is specifically for lymphangitis. Related codes cover lymphedema, not elsewhere classified (I89.0), other specified noninfective disorders of lymphatic vessels and lymph nodes (I89.8) and noninfective disorder of lymphatic vessels and lymph nodes, unspecified (I89.9).
Don't report I89.1 together with the conditions in its Excludes1 note: acute lymphangitis (L03.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
