| ICD-10: | L04.9 |
| Short Description: | Acute lymphadenitis, unspecified |
| Long Description: | Acute lymphadenitis, unspecified |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
L04.9 is a billable ICD-10 code used to specify a medical diagnosis of acute lymphadenitis, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like L04.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Lymphatic Diseases
The lymphatic system is a network of tissues and organs. It is made up of:
- Lymph - a fluid that contains white blood cells that defend against germs
- Lymph vessels - vessels that carry lymph throughout your body. They are different from blood vessels.
- Lymph nodes - glands found throughout the lymph vessels. Along with your spleen, these nodes are where white blood cells fight infection.
Your bone marrow and thymus produce the cells in lymph. They are part of the system, too.
The lymphatic system clears away infection and keeps your body fluids in balance. If it's not working properly, fluid builds in your tissues and causes swelling, called lymphedema. Other lymphatic system problems can include infections, blockage, and cancer.
