Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to Z08: its own notes plus those printed at block Z00-Z13 and Chapter 21. A note printed at a category, block or chapter applies to every code under it.
Applicable To
Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.
- Medical surveillance following completed treatment
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
Use Additional Code
Add a second code, after this one, to fully describe the condition.
Notes
General instructions on how these codes are used.
- Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00-Y89 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:
- (a) When a person who may or may not be sick encounters the health services for some specific purpose, such as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
- (b) When some circumstance or problem is present which influences the person's health status but is not in itself a current illness or injury.

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.

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, 2026 through September 30, 2027.
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 837, 847, 827, 829, 839, 846, 838, 828, 826, 848, 830, with relative weights from 0.7752 to 4.7560 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. The code appears in the Persons encountering health services for examinations (Z00-Z13) range of the CMS exempt list.
Can Z08 be reported with Z51?
Not as a rule. The Excludes1 note on Z08 lists "aftercare following medical care (Z43-Z49, Z51)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
