Malignant carcinoid tumors of the small intestine

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 4 more specific codes instead:

C7A.010 Malignant carcinoid tumor of the duodenum
C7A.011 Malignant carcinoid tumor of the jejunum
C7A.012 Malignant carcinoid tumor of the ileum
C7A.019 Malignant carcinoid tumor of the small intestine, unspecified portion

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

FY2012 Added to the draft code set draft Malignant carcinoid tumors of the small intestine
