2026 ICD-10-CM Diagnosis Code Z37.0

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 Z37.0

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 V43.0 applicable from 10/01/2025 through 09/30/2026.

Present on Admission (POA)

Z37.0 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.

Convert Z37.0 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.

Childbirth

What is childbirth?

Childbirth is the process of giving birth to a baby. It includes labor and delivery of the fetus and the placenta. The placenta is the organ that supplies food and oxygen through the umbilical cord to your fetus during pregnancy.

A full-term pregnancy is 40 weeks. Labor usually begins between 37 and 42 weeks of pregnancy. It is how your body prepares to give birth to your baby. Preterm labor can start before 37 completed weeks of pregnancy. It can lead to premature birth. Premature babies may face serious health risks.

How do I know if I'm going into labor?

Signs that you might be going into labor include:

• Regular contractions start to come closer together
• Leaking fluid or bleeding from the vagina
• Low, dull backache
• Abdominal (belly) cramps

The signs of labor, when labor starts, and the time it takes to deliver your baby can vary with each pregnancy. Call your health care provider if you have any signs of labor, even if it is before your due date.

What are the stages of labor?

Labor happens in three stages.

• The first stage begins with contractions. This stage could last for hours or days. It continues until your cervix has become thinner and dilated (stretched) to about 4 inches wide to allow your baby to pass through.
• The second stage is when you begin to push downward. Crowning is when your baby's scalp comes into view. Shortly afterward, your baby is born.
• The third stage is when you deliver the placenta, and your provider cuts the umbilical cord.

Sometimes, mothers need to have labor induced. Medicines or other methods are used to start labor. This is usually only done when the due date has passed or if a problem with the pregnancy risks the health of the mother or the fetus.

Mothers and their babies are closely monitored during labor and delivery. Delivery can occur either vaginally through the birth canal, or if there are complications, the delivery may be done surgically by a Cesarean section. This is when the baby is taken out through your abdomen (belly) and uterus.

What are the options for pain relief during childbirth?

The amount of pain during childbirth can vary based on the size and position of the baby, your level of comfort with the process, and the strength of your contractions.

Options for pain relief during labor and delivery may include:

• Medicines may reduce the pain, but they don't stop it completely.
• Natural methods ease pain without taking medicines. A few examples include using relaxation techniques, a birthing ball, massage, or taking a bath or shower.
• Combination of medicines and natural methods.

Discuss your options, risks, and benefits of pain relief during labor and delivery with your provider before your due date.
