Foliclar lymph grade III, unsp, nodes of axla and upper limb

This code signifies a diagnosis of follicular lymphoma, specifically a high-grade (Grade III) type, affecting the lymph nodes located in the axilla and/or upper limb. Follicular lymphoma is a slow-growing non-Hodgkin lymphoma, and Grade III indicates a more aggressive cellular morphology. The "unspecified" aspect refers to the absence of further subclassification of the Grade III follicular lymphoma.

Apply this code when documentation confirms Grade III follicular lymphoma localized to the axillary or upper limb lymph nodes, without further specification of the Grade III subtype (e.g., IIIa or IIIb). This code is appropriate when the physician explicitly states "follicular lymphoma Grade III" and identifies the axillary/upper limb lymph nodes as the primary site of involvement.

• Ensure the documentation clearly specifies "Grade III" follicular lymphoma and involvement of axillary/upper limb lymph nodes.
• Do not use this code if a more specific Grade III subtype (e.g., Grade IIIa or IIIb) is documented; instead, use the appropriate subcategory.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, followed by any associated symptoms or complications.
