Foliclar lymph grade III, unsp, nodes of head, face, and nk

This code signifies a high-grade follicular lymphoma, an aggressive type of non-Hodgkin lymphoma, specifically located in the lymph nodes of the head, face, or neck. "Unspecified" indicates that the exact subtype or further details about the lymphoma are not documented. This diagnosis points to a more rapidly progressing form of follicular lymphoma requiring prompt and intensive treatment.

Use this code when documentation clearly states a diagnosis of follicular lymphoma, grade III, affecting the lymph nodes in the head, face, or neck region, and no further specificity regarding the lymphoma type is provided. This code is appropriate when the pathologist's report confirms grade III follicular lymphoma and the clinician specifies the anatomical location to the head, face, or neck.

• Ensure the documentation explicitly states "grade III" for follicular lymphoma; otherwise, a lower grade or unspecified grade code may be more appropriate.
• Verify the anatomical site is specifically documented as head, face, or neck lymph nodes to avoid miscoding to other body regions.
• Always sequence this code as the primary diagnosis when it represents the reason for the encounter or admission.
