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.

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.
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).
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.
ICD-9-CM: 648.81
Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.
Childbirth Problems
Childbirth is the process of giving birth to a baby. It includes labor and delivery. Usually everything goes well, but problems can happen. They may cause a risk to the mother, baby, or both. Some of the more common childbirth problems include:
- Preterm (premature) labor, when your labor starts before 37 completed weeks of pregnancy
- Premature rupture of membranes (PROM), when your water breaks too early. If labor does not start soon afterwards, this can raise the risk of infection.
- Problems with the placenta, such as the placenta covering the cervix, separating from the uterus before birth, or being attached too firmly to the uterus
- Labor that does not progress, meaning that labor is stalled. This can happen when
- Your contractions weaken
- Your cervix does not dilate (open) enough or is taking too long to dilate
- The baby is not in the right position
- The baby is too big or your pelvis is too small for the baby to move through the birth canal
- Abnormal heart rate of the baby. Often, an abnormal heart rate is not a problem. But if the heart rate gets very fast or very slow, it can be a sign that your baby is not getting enough oxygen or that there are other problems.
- Problems with the umbilical cord, such as the cord getting caught on the baby's arm, leg, or neck. It's also a problem if cord comes out before the baby does.
- Problems with the position of the baby, such as breech, in which the baby is going to come out feet first
- Shoulder dystocia, when the baby's head comes out, but the shoulder gets stuck
- Perinatal asphyxia, which happens when the baby does not get enough oxygen in the uterus, during labor or delivery, or just after birth
- Perineal tears, tearing of your vagina and the surrounding tissues
- Excessive bleeding, which can happen when the delivery causes tears to the uterus or if you are not able to deliver the placenta after you give birth to the baby
- Post-term pregnancy, when your pregnancy lasts more than 42 weeks
If you have problems in childbirth, your health care provider may need to give you medicines to induce or speed up labor, use tools to help guide the baby out of the birth canal, or deliver the baby by Cesarean section.

Diabetes and Pregnancy
What is diabetes?
If you have diabetes, your blood glucose, or blood sugar, levels are too high. Glucose comes from the foods you eat. A hormone called insulin helps the glucose get into your cells to give them energy. With type 1 diabetes, your body does not make insulin. With type 2 diabetes, your body does not make or use insulin well. Without enough insulin, the glucose stays in your blood.
What is gestational diabetes?
Some people already have diabetes before they get pregnant. But others may develop diabetes during pregnancy. This type of diabetes is called gestational diabetes. It usually develops around the 24th week of pregnancy. It happens when your body can't make the extra insulin it needs during pregnancy. Researchers think gestational diabetes is caused by the hormonal changes of pregnancy, along with genetic and lifestyle factors.
Who is more likely to develop gestational diabetes?
Anyone who is pregnant could develop gestational diabetes. But you are more likely to develop it if you:
- Are overweight or have obesity
- Have a family history of diabetes
- Had gestational diabetes in a previous pregnancy
- Have given birth to a baby weighing 9 pounds or more
- Have polycystic ovary syndrome (PCOS)
- Are African American, Hispanic/Latino, American Indian, Alaska Native, Native Hawaiian, or Pacific Islander person
How do I know if I have gestational diabetes?
Gestational diabetes often has no symptoms. If you do have symptoms, they may be mild, such as being thirstier than normal or having to urinate (pee) more often.
If you are pregnant, you will most likely be screened for gestational diabetes between 24 and 28 weeks of pregnancy. But if you have an increased chance of developing gestational diabetes, you may be tested during your first prenatal visit. Your health care provider will use one or more blood glucose tests to check for gestational diabetes. You may have the glucose challenge test, the oral glucose tolerance test (OGTT), or both.
For these two tests, you will drink a sugary liquid and wait for an hour before your blood sample is taken. If you have an oral glucose tolerance test, you will also get your blood drawn after 2 and 3 hours.
How can diabetes affect my pregnancy?
Having diabetes during pregnancy can affect your health. For example:
- You are more likely to develop preeclampsia, a serious medical condition that causes a sudden increase in your blood pressure.
- You are more likely to need a cesarean delivery, because your baby is more likely to be bigger than average.
- Changes to your hormones and your body during pregnancy can affect your blood glucose levels. If you had diabetes before pregnancy, you may now need to adjust your meal plan, physical activity routine, and/or medicines. If you have any diabetes health problems, they may get worse during pregnancy.
- Gestational diabetes usually goes away after you have your baby. But you will be at higher risk of developing type 2 diabetes later.
Having diabetes during pregnancy can also affect the health of your developing baby:
- If you have high blood glucose levels at the beginning of your pregnancy, there is a higher risk of birth defects.
- Your baby will be at risk for obesity and type 2 diabetes later in life.
- Your baby is more likely to be born early.
- Your baby may have breathing problems or hypoglycemia (low blood glucose levels) right after birth.
- There is a higher risk of miscarriage and stillbirth.
How can I manage diabetes during pregnancy?
There are steps you can take to manage your diabetes before, during, and after pregnancy.
If you already have diabetes, the best time to control your blood glucose is before you get pregnant. High blood glucose levels can be harmful to your developing baby during the first weeks of pregnancy, even before you know you are pregnant. See your provider to help you plan for pregnancy. You can talk about how to lower the risk of health problems for you and your developing baby. You can also discuss your diet, physical activity, and which diabetes medicines are safe during pregnancy.
During your pregnancy, you will work with your provider to manage your blood glucose levels. You may be able to manage them with a healthy diet and regular physical activity. If that's not enough, then you will need to take diabetes medicines. It's also important that you:
- Get regular prenatal checkups
- Take your prenatal vitamins
- Don't use harmful substances such as alcohol, tobacco, and illegal drugs
After pregnancy, there are steps you need to take to stay healthy:
- If you had gestational diabetes, you are at risk of developing type 2 diabetes. You will be tested for it within 4 to 12 weeks after giving birth. Even if your blood glucose levels have returned to normal, you will need to get them tested every 1 to 3 years.
- If you already had diabetes before pregnancy, you and your provider will monitor changes to your blood glucose levels. They will tell you if you need to adjust your diabetes management plan.
