2025 ICD-10-CM Diagnosis Code O80
Encounter for full-term uncomplicated delivery
- ICD-10-CM Code:
- O80
- ICD-10 Code for:
- Encounter for full-term uncomplicated delivery
- Is Billable?
- Yes - Valid for Submission
- Chronic Condition Indicator: [1]
- Not chronic
- Code Navigator:
O80 is a billable diagnosis code used to specify a medical diagnosis of encounter for full-term uncomplicated delivery. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2024 through September 30, 2025. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
The code O80 is applicable to female patients aged 12 through 55 years inclusive. It is clinically and virtually impossible to use this code on a non-female patient outside the stated age range.

Clinical Classification
Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.
They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.
Uncomplicated pregnancy, delivery or puerperium
CCSR Code: PRG029
Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.
Clinical Information
Spontaneous Vertex Delivery
the birth of a cephalically presenting fetus without operative instrumentation or assistance.
Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Inclusion Terms
Inclusion TermsThese terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Delivery requiring minimal or no assistance, with or without episiotomy, without fetal manipulation e.g., rotation version or instrumentation forceps of a spontaneous, cephalic, vaginal, full-term, single, live-born infant. This code is for use as a single diagnosis code and is not to be used with any other code from chapter 15.
Use Additional Code
Use Additional CodeThe “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code to indicate outcome of delivery Z37.0
Index to Diseases and Injuries References
The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Code Edits
The Medicare Code Editor (MCE) detects errors and inconsistencies in ICD-10-CM diagnosis coding that can affect Medicare claim validity. These Medicare code edits help medical coders and billing professionals determine when a diagnosis code is not appropriate as a principal diagnosis, does not meet coverage criteria. Use this list to verify whether a code is valid for Medicare billing and to avoid claim rejections or denials due to diagnosis coding issues.
Maternity diagnoses
The Medicare Code Editor detects inconsistencies in maternity cases by checking a patient's age and any diagnosis on the patient's record. The maternity code edits apply to patients age ange is 9–64 years inclusive (e.g., diabetes in pregnancy, antepartum pulmonary complication).
Present on Admission (POA)
O80 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.
CMS POA Indicator Options and Definitions
POA Indicator: Y
Reason: Diagnosis was present at time of inpatient admission.
CMS Pays CC/MCC DRG? YES
POA Indicator: N
Reason: Diagnosis was not present at time of inpatient admission.
CMS Pays CC/MCC DRG? NO
POA Indicator: U
Reason: Documentation insufficient to determine if the condition was present at the time of inpatient admission.
CMS Pays CC/MCC DRG? NO
POA Indicator: W
Reason: Clinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission.
CMS Pays CC/MCC DRG? YES
POA Indicator: 1
Reason: Unreported/Not used - Exempt from POA reporting.
CMS Pays CC/MCC DRG? NO
Convert O80 to ICD-9-CM
Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.
Normal delivery
ICD-9-CM: 650
This is a direct match with no additional mapping qualifiers. The absence of a flag generally means the mapping is considered exact or precise. In other words, the ICD-10 code maps cleanly to the ICD-9 code without qualification, approximation, or needing multiple codes.
Patient Education
Childbirth
When you are ready to have your baby, you'll go through labor. Labor is the process of giving birth. Signs that you might be going into labor include:
- Contractions that are regular then start to come closer together
- Leaking fluid or bleeding from the vagina
- Low, dull backache
- Abdominal cramps
Call your health care provider if you have any of these signs, even if it is before your due date. Preterm labor can start before 37 completed weeks of pregnancy.
Labor happens in three stages. The first stage begins with contractions. It continues until your cervix has become thinner and dilated (stretched) to about 4 inches wide. The second stage is the active stage, in which you begin to push downward. Crowning is when your baby's scalp comes into view. Shortly afterward, your baby is born. In the third stage, you deliver the placenta. The placenta is the organ that supplied food and oxygen to your baby during pregnancy.
Mothers and babies are monitored closely during labor. Most women are able to have a baby through normal vaginal delivery. If there are complications, the baby may need to be delivered surgically by a Cesarean section.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
