Coder workflow for Z67
MedCoder structured workflow — derived from this code’s own official record
Before you code Z67
- Z67 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).

- Confirm the reason for the encounter this Z code records: a status — a condition, carrier state or sequela that may affect care, distinct from a current complication of it. Check whether the code may be reported as first-listed or principal — some Z codes are limited to one position — and do not report a history or status code for a condition documented as current. Z code categories and their reporting positions (Guidelines I.C.21.c.3, I.C.21.c.15).
Choose the right path
- Does the documentation support one of the more specific codes beneath Z67?
Yes → Select that code and continue the checks below on its own page.
No → Z67 cannot be reported as written; query for the specificity its subcategory needs.
Consider Z67. Then confirm the code is valid for the date of service in the Verify section.
Documentation check
- The provider’s diagnostic statement
- Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
- The reason for the encounter
- Whether the code records the encounter’s purpose, a status, or a history — and whether it may be first-listed (Guidelines I.C.21.c).
Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Z33.1 Pregnant state, incidental This code is a secondary code only for use when the pregnancy is in no way complicating the reason for visit. Otherwise, a code from the obstetric chapter is required. Z66 Do not resuscitate This code may be used when it is documented by the provider that a patient is on do not resuscitate status at any time during the stay. Z67 Blood type Z68 Body mass index (BMI) BMI codes should only be assigned when there is an associated, reportable diagnosis (such as obesity or anorexia) documented by the patient’s provider. Do not assign BMI codes during pregnancy. When the documentation reflects fluctuating BMI values during the current encounter for an associated reportable condition, assign a code for the most severe value.

Can Z67 be billed directly?
No. Z67 (Blood type) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
