Question:

SEER Guidelines Over Time: Should we apply the current guidelines to previously missed older cases now being reported to the central registry? See discussion.

Discussion:

1. We receive "straggler" cases for coding that were diagnosed when previous coding schemes and guidelines were applicable. When a specific guideline is in place for a given time period and is later changed in some way, we try to use the specific guideline that was in place at the time of diagnosis when coding the incoming case. However, it is not always possible to remember or to be able to access those old guidelines.

2. There are situations when coding old cases that have no applicable guideline for the older diagnosis years but current SEER documentation informs the coder how to handle the situation. For example, in the SEER Program Code Manual (3rd ed), 3 new guidelines were added for coding of differentiation. There were no guidelines in the previous SEER manual that specifically covered those situations. Should we use the current rules in coding differentiation on the older incoming case?

Answer:

Code all fields according to the instructions that were in effect at the time the case was diagnosed. If the old guidelines are unavailable or non-existent, code the case in the current scheme. The year the case was abstracted will indicate that the case was a late entry into the system and that could account for the differences in coding seen by a reviewer.
