ICD-10-CM Code For Other Noninfective Disorders Of Lymphatic Vessels And Lymph Nodes: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group I89 includes noninfective disorders of lymphatic vessels and lymph nodes such as acquired lymphangiectasia, noninfective lymphadenopathy, and related lymphatic vessel conditions that are not classified elsewhere. These ICD-10-CM diagnosis codes are used to document clinical presentations involving lymphatic vessel abnormalities, lymph node enlargement or dysfunction, and associated local complications that affect care planning and resource use. Accurate coding within the ICD-10-CM I89 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM I89: Other Noninfective Disorders Of Lymphatic Vessels And Lymph Nodes Overview

This group represents noninfective disorders affecting lymphatic vessels and lymph nodes, such as acquired lymphangiectasia and lymphadenopathy not due to infection. These conditions involve the lymphatic system and surrounding soft tissues and can impact fluid balance and immune function. Accurate coding is important for complete clinical documentation and supports appropriate reimbursement for services related to diagnosis and management.

When to Use

Use a code from this group when the clinical documentation identifies a noninfective disorder of lymphatic vessels or lymph nodes that is not better classified under another ICD-10-CM category. Select the specific code that matches the documented location, laterality if applicable, and any noted complications to reflect the clinical scenario accurately.

ICD-10-CM Codes

ICD-10-CM Code	Description
I89.0	Lymphedema, not elsewhere classified
I89.1	Lymphangitis
I89.8	Other specified noninfective disorders of lymphatic vessels and lymph nodes
I89.9	Noninfective disorder of lymphatic vessels and lymph nodes, unspecified

DRG Codes

DRG Code	Description
602	Cellulitis with MCC
603	Cellulitis without MCC
606	Minor Skin Disorders with MCC
607	Minor Skin Disorders without MCC
791	Prematurity with Major Problems
793	Full Term Neonate with Major Problems
814	Reticuloendothelial and Immunity Disorders with MCC
815	Reticuloendothelial and Immunity Disorders with CC
816	Reticuloendothelial and Immunity Disorders without CC/MCC

Typical Clinical Scenarios

An elderly patient with chronic lower extremity swelling and peau d’orange changes presents to a vascular clinic after progressive nonpitting edema and recurrent cellulitis despite compression therapy. Lymphatic imaging suggests secondary lymphedema due to prior pelvic surgery and radiation, and the clinician documents a noninfective disorder of lymphatic vessels as the primary diagnosis for ongoing management and care coordination. Typical codes: I89.0
A middle-aged patient is evaluated in the emergency department for sudden onset of axillary fullness and pain after axillary lymph node dissection for breast cancer performed two weeks earlier; there is concern for acute lymphatic obstruction without signs of infection. The presentation is managed as an acute postoperative lymphatic complication, and a code from this group is assigned to capture the noninfective lymphatic disturbance related to recent surgery. Typical codes: I89.1, I89.9
A patient with longstanding lymphedema of an arm presents to a wound care clinic for a chronic nonhealing skin ulcer overlying fibrotic lymphatic tissue; no active infection is present. The chronicity and lymphatic origin of the edema with secondary skin breakdown are documented, and a noninfective disorder of lymphatic vessels and lymph nodes code is used to describe the underlying etiology contributing to the wound. Typical codes: I89.8, I89.0
