Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to Z37: its own notes plus those printed at 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.

  • This category is intended for use as an additional code to identify the outcome of delivery on the mother's record. It is not for use on the newborn record.

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • stillbirth (P95)

Notes

General instructions on how these codes are used.

From Chapter 21 (Z00-Z99) Factors influencing health status and contact with health services applies to 1,425 codes
  • 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.

Questions About Z37Overview

What is the ICD-10 code for outcome of delivery?

Z37 is the ICD-10-CM category for outcome of delivery, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is Z37 (Outcome of delivery) a billable code?

No. This is a category header that groups the codes for outcome of delivery, and headers cannot be submitted on claims. Claims for outcome of delivery need a more specific code from this category, such as Z37.0, Z37.1, and Z37.2.

Can Z37 be reported with P95?

Not as a rule. The Excludes1 note on Z37 lists "stillbirth (P95)". 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).
