Hi Loretta,
You are correct, this edit only checks stage group if the T, N, and M values are valid for that particular site/histology. If T4 is not a valid value, then the edit would pass. The purpose of the edit is to check valid T, N, M combinations against the assigned stage group.

The edit referred to above is a CoC edit and is included in the Hosp edit set. I believe the case you described could be a Stage IIA or IIB based on the subcategory of the T2. Per AJCC, this case should have a stage group of 99 since the missing subcategory could change the stage group. NPCR, SEER, and CoC are aware of how this edit works and the scenario above has been discussed (ad nauseam) during edits WG calls will all of the standard setters present.

Standard setters may use the directly assigned T, N, and M to calculate a stage group and may choose to “downstage” to a IIA. This edit would not be run against calculated or derived stage groups.

Does that help?
