Hodgkin lymphoma, unspecified, lymph nodes of multiple sites

This code signifies a diagnosis of Hodgkin lymphoma where the specific subtype of Hodgkin lymphoma is not documented. The disease is confirmed to involve multiple lymph node regions, but the precise anatomical location of these affected nodes is not specified beyond "multiple sites."

This code is appropriate when a pathology report confirms Hodgkin lymphoma, but further subtyping (e.g., nodular sclerosis, mixed cellularity) is not provided or is pending. It should be used when documentation clearly indicates involvement of more than one lymph node region without further granular detail on the specific sites.

• Avoid using this code if a specific Hodgkin lymphoma subtype is documented; instead, use the more specific C81.0-C81.7 codes.
• Ensure documentation explicitly states "multiple sites" or similar language indicating widespread lymph node involvement without specifying individual regions.
• Query the provider for a more definitive Hodgkin lymphoma subtype and specific lymph node sites if possible, as this code represents an unspecified diagnosis.
