Sarcoidosis of lymph nodes

This code signifies sarcoidosis primarily affecting the lymphatic system, characterized by the growth of tiny collections of inflammatory cells (granulomas) within lymph nodes throughout the body. It represents a systemic inflammatory disease with a predilection for lymph node involvement, often presenting as lymphadenopathy.

Apply this code when documentation explicitly states a diagnosis of sarcoidosis with confirmed involvement of lymph nodes. This includes cases of mediastinal, hilar, or peripheral lymphadenopathy attributed to sarcoidosis, as evidenced by biopsy or imaging findings consistent with the condition.

• Always confirm that lymph node involvement is specifically documented as part of the sarcoidosis diagnosis.
• Do not use this code for sarcoidosis affecting other organs without documented lymph node involvement; use more specific codes for those manifestations.
• Consider sequencing this code as the primary diagnosis if lymph node sarcoidosis is the main reason for the encounter.
