2026 ICD-10-CM Diagnosis Code Z37.61

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 Z37.61

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)

Z37.61 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 Z37.61 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.

Stillbirth

What is a stillbirth?

If you lose a fetus at or after the 20th week of pregnancy, it's called a stillbirth. A stillbirth can occur before or during delivery and may be considered as:

• Early. The loss of a fetus between 20 and 27 weeks of pregnancy.
• Late. The loss of a fetus between 28 and 36 weeks of pregnancy.
• Term. The loss of a fetus at 37 or more weeks of pregnancy.

What are the risk factors for stillbirth?

Stillbirth can happen in any pregnancy. Some factors may increase the chance that one can occur. Risk factors can include if you:

• Are age 35 years or older
• Are of low socioeconomic status
• Smoke during pregnancy
• Have certain medical conditions, such as diabetes or high blood pressure
• Are a non-Hispanic Black woman
• Previously had a stillbirth
• Are pregnant with more than one baby (twins or triplets)

What are the possible causes of stillbirth?

In many cases, the cause remains unknown. Some causes may be preventable, but most are not.

Causes for a stillbirth may include:

How is a stillbirth diagnosed?

Before delivery, the only way to diagnose a stillbirth is to check if the fetus's heart is beating. Your health care provider may use an ultrasound to look for the fetal heartbeat.

During your pregnancy, your provider may recommend keeping track of fetal movements. However, if you don't notice movement, it doesn't always mean a stillbirth occurred. Sometimes, especially if it's your first pregnancy, it might be difficult to notice movement. If you're pregnant and something seems unusual or is worrying you, talk to your provider.

After labor and delivery, your provider will check the baby for signs of life. These can include breathing, heartbeat, voluntary movements, and pulsations in the umbilical cord. If one or more signs of life are not present, then life-saving measures are taken. If these measures are unsuccessful, a stillbirth may be diagnosed.

How do health care providers manage a stillbirth?

Care after a stillbirth depends on when it occurs. If it happens before delivery, your provider may induce (start) labor or use surgery to deliver the fetus (cesarean delivery). If it happens during labor and delivery, the placenta will still need to be removed or delivered.

No matter when it occurs, losing a pregnancy can be difficult. Counseling may help you cope with your grief. Later, if you decide to try to get pregnant again, work closely with your provider to understand any risks. Many women who have a stillbirth go on to have healthy babies.

Twins, Triplets, Multiple Births

If you are pregnant with more than one baby, you are far from alone. Multiple births are up in the United States. More women are having babies after age 30 and more are taking fertility drugs. Both boost the chance of carrying more than one baby. A family history of twins also makes multiples more likely.

Years ago, most twins came as a surprise. Now, most women know about a multiple pregnancy early. Women with multiple pregnancies should see their health care providers more often than women who are expecting one baby. Multiple pregnancy babies have a much higher risk of being born prematurely and having a low birth weight. There is also more of a risk of disabilities. Some women have to go on bed rest to delay labor. Finally, they may deliver by C-section, especially if there are three babies or more.

Parenting multiples can be a challenge. Volunteer help and support groups for parents of multiples can help.
