2025 ICD-10-CM Diagnosis Code O34.219

Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

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.

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.

MS-DRG Mapping for ICD-10-CM Code O34.219

Diagnosis-Related Groups (DRGs) are used to classify hospital cases for billing and healthcare management. They help standardize how hospitals and other providers are reimbursed for inpatient care. Patients are grouped based on their principal diagnosis into broader categories called Major Diagnostic Categories (MDCs).

Once assigned to a DRG, the hospital receives a set payment for the patient’s care, regardless of the actual services provided. This fixed rate is intended to cover the typical cost of treating patients within that group. The payment amount depends on the DRG's relative weight, which reflects the expected complexity and cost of care based on the severity of the patient’s condition.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V42.0 applicable from 10/01/2024 through 09/30/2025.

Replacement Code

O34219 replaces the following previously assigned ICD-10-CM code(s):

• O34.21 - Maternal care for scar from previous cesarean delivery

Convert O34.219 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.

Cesarean Delivery

What is a cesarean delivery?

A cesarean delivery, also called a cesarean section or c-section, is surgery to deliver a baby. The baby is taken out through your abdomen (belly). In the United States, almost one in three babies are born this way. Some cesarean deliveries are planned. Others are emergency cesarean deliveries, which are done when unexpected problems happen during delivery.

When is a cesarean delivery needed?

You may need a cesarean delivery because:

• You have health problems, including infection
• You are carrying more than one baby
• Your baby is too big
• Your baby is in the wrong position
• Your baby's health is in danger
• Labor is not moving along as it should
• There are problems with your placenta (the organ that brings oxygen and nutrients to your baby)

Not everyone who has had a cesarean delivery before will need another one next time. You may be able to have a vaginal birth after cesarean (VBAC). Talk to your health care provider about what is right for you.

How is a cesarean delivery done?

Before the surgery, you will be given pain medicine. Depending on your circumstances, you might get:

• An epidural block, which numbs the lower part of the body through an injection in the spine.
• A spinal block, which numbs the lower part of the body through an injection directly into the spinal fluid.
• General anesthesia, which makes you unconscious during the surgery. This is often used during emergency cesarean deliveries.

During the surgery, the surgeon will:

• Make a cut in your abdomen and uterus. The cut is usually horizontal, but in some cases it may be vertical.
• Open the amniotic sac and take out your baby.
• Cut the umbilical cord and the placenta.
• Close the uterus and abdomen with stitches that will later dissolve.

What are the risks of a cesarean delivery?

A cesarean delivery is relatively safe for you and your baby. But it is still a major surgery, and it carries risks. They may include:

• Infection
• Blood loss
• Blood clots in the legs, pelvic organs, or lungs
• Injury to surrounding structures, such as the bowel or bladder
• A reaction to the medicines or anesthesia used

Some of these risks do also apply to a vaginal birth. But it does take longer to recover from a cesarean delivery than from a vaginal birth. And having a cesarean delivery can raise the risk of having difficulties with future pregnancies. The more cesarean deliveries you have, the more the risk goes up.
