Clinical Information

• Fetal Viability

  the potential of the fetus to survive outside the uterus after birth, natural or induced. fetal viability depends largely on the fetal organ maturity, and environmental conditions.

• Abortion, Spontaneous

  expulsion of the product of fertilization before completing the term of gestation and without deliberate interference.

• Birth Intervals

  the lengths of intervals between births to women in the population.

• Calcium-Calmodulin-Dependent Protein Kinase Type 1

  a monomeric calcium-calmodulin-dependent protein kinase subtype that is expressed in a broad variety of mammalian cell types. its expression is regulated by the action of calcium-calmodulin-dependent protein kinase kinase. several isoforms of this enzyme subtype are encoded by distinct genes.

• Chorea Gravidarum

  a rare movement disorder developed during pregnancy, characterized by involuntary jerky motion (chorea) and inability to maintain stable position of body parts (athetosis). rheumatic fever and collagen vascular disorders are frequently associated with this disease. chorea may vary from mild to severe and occurs in approximately 1 per 2,000 to 3,000 pregnancies. (from md med j 1997 sep;46(8):436-9)

• Diabetes, Gestational

  diabetes mellitus induced by pregnancy but resolved at the end of pregnancy. it does not include previously diagnosed diabetics who become pregnant (pregnancy in diabetics). gestational diabetes usually develops in late pregnancy when insulin antagonistic hormones peaks leading to insulin resistance; glucose intolerance; and hyperglycemia.

• Family Planning Services

  health care programs or services designed to assist individuals in the planning of family size. various methods of contraception can be used to control the number and timing of childbirths.

• Gestational Weight Gain

  increase in body weight of the mother during the course of her pregnancy.

• Glycodelin

  a lipocalin that is the most abundant protein synthesized and secreted by the endometrium from mid-luteal phase of the menstrual cycle through early pregnancy.

• Hydatidiform Mole

  trophoblastic hyperplasia associated with normal gestation, or molar pregnancy. it is characterized by the swelling of the chorionic villi and elevated human chorionic gonadotropin. hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.

• Hyperemesis Gravidarum

  intractable vomiting that develops in early pregnancy and persists. this can lead to dehydration and weight loss.

• Hypertension, Pregnancy-Induced

  a condition in pregnant women with elevated systolic (>140 mm hg) and diastolic (>90 mm hg) blood pressure on at least two occasions 6 h apart. hypertension complicates 8-10% of all pregnancies, generally after 20 weeks of gestation. gestational hypertension can be divided into several broad categories according to the complexity and associated symptoms, such as edema; proteinuria; seizures; abnormalities in blood coagulation and liver functions.

• Illegitimacy

  the state of birth outside of wedlock. it may refer to the offspring or the parents.

• Luteoma

  an ovarian neoplasm composed of luteal cells derived from luteinized granulosa cells and theca cells. luteomas respond to gonadotropins, and vary in their hormone production (progesterone; estrogens; or androgens). during pregnancy, a transient type of luteoma may develop due to an exaggerated luteinization of the ovary.

• Phenylketonuria, Maternal

  a condition occurring in untreated or partially treated females with phenylketonuria when they become pregnant. this may result in damages to the fetus, including microcephaly; mental retardation; congenital heart disease; fetal growth retardation; and craniofacial abnormalities. (from am j med genet 1997 mar 3;69(1):89-95)

• Placental Lactogen

  a polypeptide hormone of approximately 25 kda that is produced by the syncytiotrophoblasts of the placenta, also known as chorionic somatomammotropin. it has both growth hormone and prolactin activities on growth, lactation, and luteal steroid production. in women, placental lactogen secretion begins soon after implantation and increases to 1 g or more a day in late pregnancy. placental lactogen is also an insulin antagonist.

• Pre-Eclampsia

  a complication of pregnancy, characterized by a complex of symptoms including maternal hypertension and proteinuria with or without pathological edema. symptoms may range between mild and severe. pre-eclampsia usually occurs after the 20th week of gestation, but may develop before this time in the presence of trophoblastic disease.

• Pregnancy

  the status during which female mammals carry their developing young (embryos or fetuses) in utero before birth, beginning from fertilization to birth.

• Pregnancy Complications

  conditions or pathological processes associated with pregnancy. they can occur during or after pregnancy, and range from minor discomforts to serious diseases that require medical interventions. they include diseases in pregnant females, and pregnancies in females with diseases.

• Pregnancy Complications, Cardiovascular

  the co-occurrence of pregnancy and a cardiovascular disease. the disease may precede or follow fertilization and it may or may not have a deleterious effect on the pregnant woman or fetus.

• Pregnancy Complications, Hematologic

  the co-occurrence of pregnancy and a blood disease (hematologic diseases) which involves blood cells or coagulation factors. the hematologic disease may precede or follow fertilization and it may or may not have a deleterious effect on the pregnant woman or fetus.

• Pregnancy Complications, Infectious

  the co-occurrence of pregnancy and an infection. the infection may precede or follow fertilization.

• Pregnancy Complications, Neoplastic

  the co-occurrence of pregnancy and neoplasms. the neoplastic disease may precede or follow fertilization.

• Pregnancy Complications, Parasitic

  the co-occurrence of pregnancy and parasitic diseases. the parasitic infection may precede or follow fertilization.

• Pregnancy in Adolescence

  pregnancy in human adolescent females under the age of 19.

• Pregnancy in Diabetics

  the state of pregnancy in women with diabetes mellitus. this does not include either symptomatic diabetes or glucose intolerance induced by pregnancy (diabetes, gestational) which resolves at the end of pregnancy.

• Pregnancy Maintenance

  physiological mechanisms that sustain the state of pregnancy.

• Pregnancy Outcome

  results of conception and ensuing pregnancy, including live birth; stillbirth; or spontaneous abortion. the outcome may follow natural or artificial insemination or any of the various assisted reproductive techniques, such as embryo transfer or fertilization in vitro.

• Pregnancy Proteins

  proteins produced by organs of the mother or the placenta during pregnancy. these proteins may be pregnancy-specific (present only during pregnancy) or pregnancy-associated (present during pregnancy or under other conditions such as hormone therapy or certain malignancies.)

• Pregnancy Rate

  the ratio of the number of conceptions (conception) including live birth; stillbirth; and fetal losses, to the mean number of females of reproductive age in a population during a set time period.

• Pregnancy Reduction, Multifetal

  selective abortion of one or more embryos or fetuses in a multiple gestation pregnancy. the usual goal is to improve the outcome for the remaining embryos or fetuses.

• Pregnancy Tests

  tests to determine whether or not an individual is pregnant.

• Pregnancy Tests, Immunologic

  methods of detecting pregnancy by examining the levels of human chorionic gonadotropin (hcg) in plasma or urine.

• Pregnancy, Ectopic

  a potentially life-threatening condition in which embryo implantation occurs outside the cavity of the uterus. most ectopic pregnancies (>96%) occur in the fallopian tubes, known as tubal pregnancy. they can be in other locations, such as uterine cervix; ovary; and abdominal cavity (pregnancy, abdominal).

• Pregnancy, Heterotopic

  multiple pregnancy with embryo implantation occuring at different locations, involving both an intrauterine site and an extrauterine (ectopic pregnancy) site.

• Pregnancy, High-Risk

  pregnancy in which the mother and/or fetus are at greater than normal risk of morbidity or mortality. causes include inadequate prenatal care, previous obstetrical history (abortion, spontaneous), pre-existing maternal disease, pregnancy-induced disease (gestational hypertension), and multiple pregnancy, as well as advanced maternal age above 35.

• Fertilization

  the fusion of a spermatozoon (spermatozoa) with an ovum thus resulting in the formation of a zygote.

• Menstruation

  the periodic shedding of the endometrium and associated menstrual bleeding in the menstrual cycle of humans and primates. menstruation is due to the decline in circulating progesterone, and occurs at the late luteal phase when luteolysis of the corpus luteum takes place.

• Quadruplets

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

• 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).
• Diagnoses for females only - The Medicare Code Editor detects inconsistencies between a patient’s sex and any diagnosis on the patient’s record, these edits apply to FEMALES only .
• Unacceptable principal diagnosis - There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Convert Z33.1 to ICD-9-CM

• ICD-9-CM Code: V22.2 - Preg state, incidental
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Pregnancy

You're going to have a baby! It's an exciting time, but it can also feel a bit overwhelming. You may have a lot of questions, including what you can do to give your baby a healthy start. To keep you and your baby healthy during pregnancy, it is important to:

• Have regular visits with your health care provider. These prenatal care visits help make sure that you and your baby are healthy. And if there are any health problems, your provider can find them early. Getting treatment right away can cure many problems and prevent others.
• Eat healthy and drink plenty of water. Good nutrition during pregnancy includes eating a variety of
• Fruits
• Vegetables
• Whole grains
• Lean meats or other protein sources
• Low-fat dairy products
• Take prenatal vitamins. Pregnant women need higher amounts of certain vitamins and minerals, such as folic acid and iron.
• Be careful with medicines. Always check with your health care provider before you start or stop any medicine. This includes over-the-counter medicines and dietary or herbal supplements.
• Stay active. Physical activity can help you stay strong, feel and sleep better, and prepare your body for birth. Check with your provider about which types of activities are right for you.
• Avoid substances that could hurt your baby, such as alcohol, drugs, and tobacco.

Your body will keep changing as your baby grows. It can be hard to know whether a new symptom is normal or could be a sign of a problem. Check with your health care provider if something is bothering or worrying you.
