HospSeq/Site Override

Edits of the type, Seq Num--Hosp, Primary Site, Morph, differ in use of ICD-O-2 or ICD-O-3 morphology. They force review of multiple primary cancers when one of the primaries is coded to a site-morphology combination that could indicate a metastatic site rather than a primary site. If ACoS Sequence Number indicates the person has had more than one primary, then any case with one of the following site-histology combinations requires review:

• C76.0–C76.8 (Ill-defined sites) or C80.9 (unknown primary) and ICD-O-2 or ICD-O-3 histology < 9590. (Look for evidence that the unknown or ill-defined primary is a secondary site from one of the patient's other cancers. For example, a clinical discharge diagnosis of "abdominal carcinomatosis" may be attributable to the patient's primary ovarian cystadenocarcinoma already in the registry, and should not be entered as a second primary.)
• C77.0-C77.9 (lymph nodes) and ICD-O-2 histology not in range 9590-9717 or ICD-O-3 histology not in the range 9590-9729; or C42.0-C42.4 and ICD-O-2 histology not in range 9590-9941 or ICD-O-3 histology not in the range 9590-9989. (That combination is most likely a metastatic lesion. Check whether the lesion could be a manifestation of one of the patient's other cancers.)
• Any site and ICD-O-2 histology in the range 9720-9723, 9740-9741 or ICD-O-3 histology in the range 9740-9758. (Verify that these diagnoses are coded correctly and are indeed separate primaries from the others.)

If it turns out that the suspect tumor is a manifestation of one of the patient's other cancers, delete the metastatic or secondary case, re-sequence remaining cases, and correct the coding on the original case as necessary.

Instructions for Coding

• Leave blank if the EDITS program does not generate an error message for an edit of the type Seq Num--Hosp, Primary Site, Morph
• Leave blank and correct any errors for the case if an item is discovered to be incorrect.
• Code 1 if review of all items in the error or warning message confirms that all are correct.
