Other Hodgkin lymphoma, unspecified site

This code identifies a diagnosis of Hodgkin lymphoma that does not fit into the classic or nodular lymphocyte-predominant subtypes, and where the primary site of involvement is not specified in the medical record. This represents a less common or unclassifiable form of Hodgkin lymphoma.

Use this code when the pathology report confirms Hodgkin lymphoma, but the specific subtype is documented as "other" or "unspecified," and the anatomical location of the primary tumor is not clearly indicated. This code is appropriate when the clinician has not provided sufficient detail to assign a more specific Hodgkin lymphoma code.

• Avoid using this code if a more specific subtype (e.g., classic Hodgkin lymphoma, nodular sclerosis) is documented.
• Query the provider for clarification on the specific subtype and primary site if possible to allow for more precise coding.
• This code should be sequenced as the primary diagnosis when it is the reason for the encounter, unless treatment for a complication is the focus.
