2025 ICD-10-CM code I89.1

Lymphangitis.

Code I89.1 is used to report chronic, subacute, and NOS lymphangitis.Acute lymphangitis is coded differently (L03.-).It is important to distinguish between these conditions for accurate coding.

Medical necessity for lymphangitis treatment is established by the presence of signs and symptoms of infection and inflammation of the lymphatic vessels.Appropriate diagnostic and therapeutic interventions are medically necessary to prevent potential complications such as sepsis, abscess formation, and chronic lymphedema.

Diagnosis and treatment of lymphangitis is typically managed by physicians specializing in infectious diseases, internal medicine, or family medicine.In some cases, surgical specialists may be consulted if surgical intervention is necessary for complications like abscess drainage.

In simple words: Lymphangitis is an inflammation of the lymph vessels, which are part of the body's immune system.

Inflammation of lymphatic vessels.Includes: chronic lymphangitis, lymphangitis NOS, subacute lymphangitis.

Example 1: A patient presents with red streaks on their arm, along with swelling, pain, and fever. These symptoms are consistent with lymphangitis, an infection of the lymphatic vessels. The physician examines the patient, takes a medical history, and may order blood tests to confirm the diagnosis and identify the causative organism. Treatment usually includes antibiotics., Following a minor skin injury, a patient develops localized inflammation and tenderness in the lymph nodes near the affected area. The inflammation spreads along the lymphatic vessels, exhibiting as red streaks, indicating lymphangitis. The patient also experiences systemic symptoms like fever and chills.The underlying skin infection and lymphangitis are treated with antibiotics., A patient with a history of chronic venous insufficiency develops cellulitis, a bacterial skin infection, in their lower leg. The infection progresses, and the patient subsequently develops lymphangitis, evident by the presence of red streaks extending from the site of cellulitis. This requires prompt medical attention, typically with antibiotics and elevation of the affected limb.

Documentation for lymphangitis should include the location and extent of the inflammation, the presence of any associated symptoms (e.g., fever, chills, pain, swelling), results of any laboratory tests, prescribed treatment, and the patient's response to treatment.

** Lymphangitis often arises from a localized infection that spreads to the lymphatic system. Prompt diagnosis and treatment are essential to prevent serious complications.
