Note: Store and display Age at Diagnosis as three digits. For example: 000, 003, 015, 065, or 112. (Refer to Age at Diagnosis., Allowable Values section)
If either of the following conditions is true:
Date of Birth year is NOT a valid year (1800-2300)
Date of Diagnosis year is NOT a valid year (1800-2300)
Then set Age at Diagnosis to 999 and stop here.
Otherwise, perform the following steps in the order listed:
1) Subtract Date of Birth year from Date of Diagnosis year to set the initial year-based Age at Diagnosis value (3 digits, right-justified).
2) If all of the following conditions are true:
Date of Diagnosis month is a valid month (01-12)
Date of Birth month is a valid month (01-12)
Date of Diagnosis month is earlier than (<) the Date of Birth month
Then subtract 1 from Age at Diagnosis.
3) If all of the following conditions are true:
Date of Diagnosis month is a valid month (01-12)
Date of Birth month is a valid month (01-12)
Date of Diagnosis month is the same as the Date of Birth month
Date of Diagnosis day is a valid day (01-31)
Date of Birth day is a valid day (01-31)
Date of Diagnosis day is earlier than (<) the Date of Birth day
Then subtract 1 from Age at Diagnosis.
4) If Age at Diagnosis is now > 120, then reset it to 120.
5) If Age at Diagnosis is now < 000, then reset it to 000 (in utero).
