III.2.5.1 Number and Street at DX

Enter the patient’s street number and street name at diagnosis.

House numbers must precede the street name.
Insert a single space between each component in the street address (e.g., "NEW MONTGOMERY STREET").
Direction (e.g., North, West) and street types (e.g., Avenue, Road) may be abbreviated (e.g., N MAIN ST). However, do not abbreviate a direction that is the name of a street (e.g., 123 NORTH ST).
Use intersection addresses (e.g., "FOURTH AND MAIN"), post office box numbers, and building names (e.g., "HOTEL NEW HAMPSHIRE") only if an exact address is not available in the medical record, business office, or elsewhere.
Place a unit designation directly after the house number (e.g., "139A MAIN ST") or after the street name (e.g., "106 CHURCH STREET 1ST FLOOR," "36 EASTERN CIRCLE APT A").
If the address contains more than 60 characters, omit the least important elements, such as the apartment or space number.

Do not omit elements needed to locate the address in a census tract, such as house number, street, direction or quadrant, and street type.

Abbreviate as needed, using the standard address abbreviations listed in the U.S. Postal Service National Zip Code and Post Office Directory published by the U.S. Postal Service.
If the address cannot be determined, enter the word "UNKNOWN."
The field, Patient Address at Diagnosis Supplemental provides the ability to record additional address information such as the name of a place or facility (i.e., a nursing home or name of an apartment complex) at the time of diagnosis.

Use up to 60 characters for this field.
If the patient has multiple tumors, the address may be different for subsequent primaries.
Do not update this data item if the patient's address changes.
