Question:

Histology (Pre-2007): What code is used to represent the histology for a "malignant invasive gastrointestinal stromal tumor (GIST)"?

Discussion:

Answer:

For tumors diagnosed 2001-2006: Malignant GIST is coded 8936/3.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

History:

For cases diagnosed prior to 1/1/01: Malignant GIST is coded as stromal sarcoma 8930/3.
