Coding Instructions

1.  When multiple tumors are present at diagnosis, record the date of diagnosis.

Example 1:  The patient has multiple tumors; a 2cm infiltrating duct carcinoma in the LIQ and a 1cm infiltrating duct carcinoma in the UIQ of the left breast.  According to the breast multiple primary rules, these tumors are accessioned as a single primary.  Enter the date of diagnosis in Date of Multiple Tumors.

Example 2:  Operative report for TURB mentions multiple bladder tumors.  Pathology report: Papillary transitional cell carcinoma present in tissue from bladder neck, dome, and posterior wall.  According to the Bladder, Renal Pelvis, and Ureter multiple primary rules these tumors are accessioned as a single primary.  Enter the date of diagnosis in Date of Multiple Tumors.

2.  When subsequent tumor(s) are counted as the same primary, record the date the second/subsequent tumor was diagnosed.  Update the multiplicity counter at this time.

Example:  Patient has an excisional biopsy of a single tumor in the soft palate on January 2, 2007.  The pathology shows clear margins.  Record 01 in the Multiplicity Counter field.  On July 10, 2007, another tumor is excised from the soft palate.  The multiple primary rules for head and neck state that this tumor is the same primary.  Change the 01 in Multiplicity Counter to 02 and enter 07102007, the date the second tumor was diagnosed, in Date of Multiple Tumors.

3.  Leave this field blank for cases diagnosed prior to 1/1/2007.
