RE: FY 2019 IPF ICD-10 Updates - Comorbidity Categories
The Oncology Treatment comorbidity category file originally posted
to the CMS website in early August 2018 erroneously continued to 
include 3 codes that had been removed for unspecified laterality.  Those 
3 codes have been removed from the attached comorbidity files.
The 3 codes removed are:
"C002            Malignant neoplasm of external lip, unspecified"
"C005            Malignant neoplasm of lip, unspecified, inner aspect"
C44291       Other specified malignant neoplasm of skin of unspecified ear and external auricular canal
