These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Cancer
Cancer is not just one disease but many diseases. Cancer begins in your cells, which are the building blocks of your body. Usually, your body forms new cells as needed, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should.

Code HistoryHistory
Questions About Z08Overview
Is Z08 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report encounter for follow-up examination after completed treatment for malignant neoplasm on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does Z08 group to?
On inpatient claims, encounter for follow-up examination after completed treatment for malignant neoplasm maps to MS-DRG 826, 827, 828, 829, 830, 837, 838, 839, 846, 847, 848, with relative weights from 0.8494 to 4.8043 depending on complications. Higher weights mean higher Medicare reimbursement.
Can Z08 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because encounter for follow-up examination after completed treatment for malignant neoplasm describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z08 exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for encounter for follow-up examination after completed treatment for malignant neoplasm on inpatient claims.
What is the ICD-9 equivalent of Z08?
Under the General Equivalence Mappings, encounter for follow-up examination after completed treatment for malignant neoplasm converts to ICD-9-CM V67.01 (follow-up vag pap smear), V67.1 (radiotherapy follow-up), and V67.2 (chemotherapy follow-up). The mapping is approximate, so confirm the match fits the documentation.
