Question:

MP/H Rules/Multiple primaries--Thyroid: How many primaries should be coded in a patient with a 4/5/08 left thyroid lobectomy diagnosis of follicular carcinoma followed by a 7/25/08 right thyroid lobectomy diagnosis of papillary carcinoma, follicular variant?

Discussion:

Answer:

For cases diagnosed 2007 or later:

Rule M17 under Other Sites applies. These are separate primaries based on their ICD-O-3 histology codes. Follicular carcinoma is coded 8330. Papillary carcinoma, follicular variant is coded 8340. The histology codes are different at the third number. Rule M6 does not apply because these diagnoses are more than 60 days apart.
