Foliclar lymph grade III, unsp, extrnod and solid org sites

This code signifies a high-grade, aggressive form of follicular lymphoma that has spread beyond the lymph nodes to involve other organs or tissues. It indicates that the specific subtype of grade III follicular lymphoma (e.g., grade IIIa or IIIb) is not specified in the medical record.

Use this code when documentation confirms a diagnosis of follicular lymphoma, grade III, with involvement of extranodal sites or solid organs, and the specific grade III subtype is not further detailed. This typically applies to pathology reports or physician notes explicitly stating "follicular lymphoma grade III, extranodal" or "solid organ involvement, unspecified grade III."

• Ensure documentation clearly specifies "grade III" and extranodal/solid organ involvement.
• Do not use if the specific grade III subtype (e.g., IIIa or IIIb) is documented; use the more specific code.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter or treatment.
