Answer:
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Clinical size can be coded when the patient has had surgery. For the case above, code the tumor size as 015 [1.5 cm] using the clinical information. The CS Tumor Size/Extent Eval field refers to both tumor size and extension. In this case, record the eval field as 0 or 1 (which ever is appropriate). The tumor size sets the T category unless the resection shows skin or chest wall or dermal lymphatic involvement.
