ICD-10 Code O07.1: Delayed or excessive hemorrhage after failed termination

Key Takeaways

ICD-10 Code O07.1 is the billable ICD-10-CM code for delayed or excessive hemorrhage following failed attempted termination of pregnancy, valid for 2026 submission.

Applicable To inclusions cover afibrinogenemia, defibrination syndrome, hemolysis, and intravascular coagulation following failed attempted abortion.

O07.1 captures hemorrhagic complications specifically. Use O07.4 when failed termination has no complication, and O07.0 for genital tract infection.

Pabau’s claims management software supports accurate ICD-10 diagnostic code entry and documentation workflows for obstetric and gynecology practices.

ICD-10 Code O07.1 is the billable ICD-10-CM code for delayed or excessive hemorrhage following a failed attempted termination of pregnancy. It sits under the O07 category, which covers every complication of an unsuccessful termination attempt: Infection, embolism, hemorrhage, or none at all. O07.1 is the specific child code for the hemorrhagic and coagulopathic presentations.

Coders working this code family run into the same mix-ups on repeat: Pairing O07.1 with the wrong O07 sibling, confusing a failed attempt with a completed induced termination that carries its own hemorrhage code, or submitting the non-billable O07 header by mistake.

This reference covers the Applicable To inclusions, the full O07 sibling set, the excludes notes, and the coding guidelines that keep O07.1 claims audit-ready for OB/GYN and reproductive health billing.

ICD-10 Code O07.1: Definition and billable status

Most claim denials for obstetric complication codes trace back to one error: Submitting a parent header code instead of the specific billable child. Claims management software catches this at entry, but coders still need to know which code to reach for.

ICD-10 Code O07.1 is the correct billable code when a patient presents with delayed or excessive hemorrhage following failed attempted termination of pregnancy.

O07.1 is a specific, billable ICD-10-CM code valid for all claims submitted in fiscal year 2026. Its parent, O07, covers the broader category of failed attempted termination of pregnancy but is itself non-billable. Coders must always select a child code at the O07.x level.

Applicable To: Conditions included under O07.1

The ICD-10-CM tabular list specifies an “Applicable To” note for O07.1 that extends the code’s scope beyond the literal code descriptor. According to the WHO ICD-10 browser, the inclusion terms for O07.1 cover the following hemorrhagic and coagulopathic sequelae of failed attempted abortion:

• Afibrinogenemia following failed attempted abortion
• Defibrination syndrome following failed attempted abortion
• Hemolysis following failed attempted abortion
• Intravascular coagulation following failed attempted abortion

These four conditions represent distinct pathophysiological mechanisms, but all map to O07.1 because they result from bleeding complications after the failed procedure. Coders do not need a separate code for each condition. O07.1 captures all of them when linked to a failed attempted termination.

Note that WHO ICD-10 and ICD-10-CM (the US clinical modification maintained by CDC/NCHS) occasionally differ in inclusion term wording. Always verify the specific ICD-10-CM tabular inclusion list from the current CMS release for claim submission purposes.

O07.1 within the O07 code family

O07 is the non-billable parent category for all complications of failed attempted termination of pregnancy. Billing staff at OB/GYN practices need to select the correct child code: O07.0, O07.1, O07.2, and O07.4 are billable at the four-character level, while O07.3 needs an added fifth character (O07.30–O07.39) before it can be submitted on a claim.

The table below shows the full O07 subcode set with descriptions.

Each subcode represents a mutually exclusive complication type. Selecting the wrong sibling code is a common audit trigger because payers cross-reference the documented clinical presentation against the submitted code.

O07.1 vs. other O07 sibling codes: When to use each

The five O07.x subcategories are not interchangeable, and O07.3 needs that added fifth character before it is billable. Choosing between them depends entirely on what the physician has documented as the primary complication. Here is how to differentiate them in practice.

Use O07.1 when: The record documents delayed or excessive hemorrhage, including the coagulopathic sequelae listed in the Applicable To note (afibrinogenemia, defibrination syndrome, hemolysis, intravascular coagulation). Postabortion hemorrhage that requires transfusion, operative intervention, or extended monitoring maps here.

Use O07.0 when: The complication is infectious rather than hemorrhagic. Endometritis, parametritis, salpingitis, or pelvic peritonitis following a failed attempt are genital tract and pelvic infections that belong to O07.0, not O07.1. A patient with both infection and hemorrhage may warrant dual coding depending on which condition drove the admission.

Use O07.2 when: The documented complication is embolism, including air embolism, pulmonary embolism, or thromboembolism arising from the failed procedure. Embolism and hemorrhage are distinct. Do not conflate them.

Use O07.3 when: A complication is clearly documented but does not fall into infection, hemorrhage, or embolism categories. This is the residual “other and unspecified” bucket, and it should not be the default choice when a more specific code applies. Remember that O07.3 alone is not billable. A fifth character (O07.30–O07.39) completes the code for claim submission.

Use O07.4 when: The physician explicitly documents no complication from the failed termination attempt. This is the clean, uncomplicated scenario. Assigning O07.4 when the record documents hemorrhage is a coding error that invites payer scrutiny.

ICD-10-CM excludes notes for O07.1

Excludes notes define the boundaries of a code’s application. Ignoring them produces claim edits that are difficult to reverse. Coders working with digital documentation forms should confirm the clinical context aligns with the correct code range before submission.

O07 carries an Includes note confirming its scope: Failure of attempted induction of termination of pregnancy, and incomplete elective abortion, both belong under this category.

Its Excludes1 note is narrower than coders sometimes assume. It excludes only incomplete spontaneous abortion (O03.0-), meaning a miscarriage still in progress is never coded here. A hemorrhagic or other complication tied to a failed attempted termination stays under O07 regardless of how the pregnancy began.

O03.0- carries that Excludes1 relationship with O07, so the two codes are never reported together. A spontaneous abortion in progress and a failed attempted termination describe different clinical scenarios.

O04 (complications following induced termination of pregnancy) carries an Excludes2 relationship instead, which means both codes can be assigned together when the documentation supports a completed induced termination alongside a separate failed attempt. Confirm the procedure status in the physician’s documentation before coding either scenario.

Coding guidelines for ICD-10 Code O07.1 in clinical practice

Postabortion hemorrhage coded under O07.1 follows the same sequencing principles that govern all Chapter 15 codes. These guidelines apply to reproductive health clinics as much as to hospital-based OB departments.

1. Chapter 15 codes take sequencing priority. When a patient is admitted for a pregnancy-related condition, a code from Chapter 15 (O00-O9A) is sequenced as the principal diagnosis unless the encounter is for a completely unrelated condition. O07.1 should be the principal diagnosis when hemorrhage from the failed termination is the reason for the encounter.
2. Additional codes may be required. When the hemorrhagic complication results in a specific condition (such as disseminated intravascular coagulation), an additional code from the appropriate chapter may be assigned as a secondary diagnosis to capture the full clinical picture.
3. Trimester coding does not apply here. Unlike many Chapter 15 codes, O07.1 does not carry trimester-specific variants. The code is applied regardless of the gestational age at which the failed attempt occurred.
4. Only one outcome code per delivery. If the encounter also involves a liveborn outcome, assign a Z3A code for weeks of gestation as applicable. Confirm with the attending physician whether a delivery outcome code is appropriate given the failed termination context.
5. 7th character extensions are not required. O07.1 is a four-character code with no 7th character extension required. Attempts to append a 7th character will produce an invalid code error on submission.

O07.1 code history and annual validity

ICD-10-CM codes are updated annually, effective October 1. Coders verifying the validity of O07.1 across recent fiscal years can use the AAPC Codify ICD-10-CM lookup for quick reference alongside the official CMS release files.

O07.1 has remained stable across recent update cycles with no description changes or code retirement. Always cross-check against the current-year CMS tabular list before billing to confirm ongoing validity, as annual update cycles can affect any code.

Related ICD-10-CM codes for obstetric hemorrhage

O07.1 sits within the O00-O08 block (pregnancy with abortive outcome), but obstetric hemorrhage codes extend throughout Chapter 15. Understanding the adjacent codes prevents miscoding when the clinical context involves hemorrhage in a different phase of pregnancy or from a different cause. Practices using patient care management systems benefit from having these crosswalks embedded in their coding workflows.

The most common coding confusion involves O04.6 vs. O07.1. The clinical distinction is whether the termination procedure was attempted but failed (O07.1 family) or whether the procedure was carried out and resulted in a completed induced termination with subsequent hemorrhage (O04.6). Physician documentation must explicitly state the procedure outcome for accurate code selection.

For broader context on a related complication code, O04.7 covers embolism following a completed induced abortion, the same complication type as O07.2 but for a different procedure outcome. Practices managing ICD-10 workflows across specialties also benefit from reviewing HIPAA compliance requirements to ensure documentation practices meet federal standards.

How Pabau supports obstetric and gynecology coding workflows

Accurate ICD-10 code assignment depends on having the right documentation at the right moment in the clinical workflow. OB/GYN EMR software built for reproductive health practices helps clinicians capture the procedure outcome, complication type, and supporting clinical details before the encounter closes.

Practice management software like Pabau keeps clinical notes, diagnoses, and billing codes linked within a single patient file through its client record module. This keeps documentation and code selection tightly linked, cutting down on O07.x miscoding.

The digital forms feature allows practices to build procedure-specific intake and post-procedure documentation templates that prompt clinicians to record complication type explicitly, giving coders the information they need without a separate query cycle.

For practices operating across complex medical form workflows, centralized documentation reduces the risk of coders working from incomplete records. Practices coding conditions like C55 alongside pregnancy-related complications benefit from having a unified coding reference integrated with their practice management workflow.

Conclusion

Delayed or excessive hemorrhage following a failed termination attempt is a clinically specific complication, and ICD-10 Code O07.1 captures it precisely. Getting the O07.x selection right requires one thing above all: Clear physician documentation of the complication type before the coder touches the chart.
