Question:
Date of Diagnosis--All Sites: Is it better to estimate the month in the date of diagnosis field using the re-excision pathology report date or code the month to unknown if the only available information is the re-excision date? See discussion.
Discussion:
The only available information is the following pathology report:
On 7/18/00 a wide excision of the primary lesion is done. The report reads, "Lesion approximately 1 cm. Residual superficial spreading malignant melanoma with deepest penetration 4 mm."
Answer:
Code the Date of Diagnosis field to 07/2000 for this case. Estimate the month of diagnosis whenever possible.
Given the usual delay between the initial excision of the lesion and a wide excision for a melanoma, estimate the month of diagnosis as July.
