Secondary malignant neoplasm of lung

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 3 more specific codes instead:

C78.00 Secondary malignant neoplasm of unspecified lung
C78.01 Secondary malignant neoplasm of right lung
C78.02 Secondary malignant neoplasm of left lung

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 Secondary malignant neoplasm of lung

Official coding rules

Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.

Excludes1 - never coded here

secondary carcinoid tumors of liver (C7B.02)
secondary carcinoid tumors of peritoneum (C7B.04)

Excludes2 - not included here

lymph node metastases (C77.0)

How CDC's index refers to this code
