About coding Lymphangiectasis
The ICD-10-CM code for Lymphangiectasis is I89.0 (Lymphedema, not elsewhere classified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I89.0.
Within I89 (other noninfective disorders of lymphatic vessels and lymph nodes), I89.0 is specifically for lymphedema, not elsewhere classified. Related codes cover lymphangitis (I89.1), 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 I89.0 together with the conditions in its Excludes1 note: postmastectomy lymphedema (I97.2).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
