Is Z29 billable?

No — Z29 is a non-billable header code. Z29 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 8 billable codes beneath Z29.

Excludes1 — never code together

The conditions below can never be reported together with Z29 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • desensitization to allergens (Z51.6)
  • prophylactic surgery (Z40.-)
