III.2.5.4 State at DX

The State at Diagnosis data item identifies the patient's state of residence at time of diagnosis.

• Use U.S. Postal Service abbreviations for the state, territory, commonwealth, U.S. possession, or Canadian province or territory in which the patient resides at the time the tumor is diagnosed and treated.
• If the patient has multiple tumors, the state of residence may be different for subsequent primaries.
• If the patient is a foreign resident, then code either XX or YY depending on the circumstance.
• Do not update this data item if the patient's state or residence changes.

For states in the U.S. and provinces in Canada, enter the standard two letter Postal Service abbreviation.

California is CA.
