O65 ICD-10-CM Code: Obstructed labor due to maternal pelvic abnormality

Billing Status: NO. This is a non-billable ICD-10-CM code: report a more specific billable code beneath it.

Coder workflow for O65

MedCoder structured workflow — derived from this code’s own official record

Before you code O65

  1. O65 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).

    ReviewO65.0, O65.1, O65.2, O65.3, O65.4, O65.5, O65.8, O65.9

    See the relationships section · Guide: How to choose an ICD-10-CM code →

  2. O65’s title joins a condition with an associated condition or complication. Confirm each component is documented. Where the classification presumes the link through the “with” convention, only a provider statement that the conditions are unrelated defeats it. A combination code is assigned only when it fully identifies the documented conditions; a required second code for the stage, type or manifestation is still reported when the notes ask for it (Guidelines I.B.9, I.A.15).

    Guide: Combination codes →

  3. Confirm the condition is documented as complicating the pregnancy, childbirth, or the puerperium, and check the trimester where the code carries one and the fetus character where the category requires it. Chapter 15 codes belong on the maternal record only and take sequencing priority over codes from other chapters. It is the provider’s responsibility to state that a condition is not affecting the pregnancy; the trimester is assigned from the documentation (Guidelines I.C.15.a, I.C.15.a.1, I.C.15.a.3).

Choose the right path

  1. Does the documentation support one of the more specific codes beneath O65?
    Yes → Select that code and continue the checks below on its own page.
    No → O65 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewO65.0, O65.1, O65.2, O65.3, O65.4, O65.5, O65.8, O65.9

Consider O65. 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).
Trimester
Assigned from the documented trimester at the encounter, or the trimester in which the condition developed for inpatient stays (Guidelines I.C.15.a.3).
The associated condition or complication
Whether the associated condition the title names is documented; the “with” convention presumes some links, and a provider statement that the conditions are unrelated defeats it (Guidelines I.A.15).

Coding decision scenarios

Pattern scenarios for this code’s structure — decision rules, not clinical cases

Documentation: Only one of the components this code’s title joins is documented.

Coding question: Is O65 supported?

Path: Review the code for the documented component on its own.

Reason: A combination code is assigned only when it fully identifies the documented conditions; otherwise the documented component takes its own code (Guidelines I.B.9).

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.

Code Overview

Obstructed labor due to maternal pelvic abnormality is a non-billable ICD-10-CM category code (O65). A more specific billable subcode must be selected for claims submission.
