Question:

Grade, Differentiation: Is grade always coded to 4 for a diagnosis of Ewing's sarcoma?

Discussion:

Answer:

Do not code the ICD-O-3 grade for Ewing sarcoma unless documented in the record.

In the TNM system, grade is required to place Ewing sarcoma into a stage group. For TNM staging purposes, Ewing sarcoma is classified as G4. Do not apply TNM rules to ICD-O coding.
