Usually, there are three primary characteristics of this condition, including the following:
High blood pressure can affect a pregnancy by causing adverse effects on both mother and fetus. Chronic hypertension while pregnant may lead to impairment of the fetus’ growth, a higher risk of the placenta separating from the uterus, problems breathing during labor, and other side effects.
O13. 9 - Gestational [pregnancy-induced] hypertension without significant proteinuria, unspecified trimester. ICD-10-CM.
ICD-10 Code for Personal history of other complications of pregnancy, childbirth and the puerperium- Z87. 59- Codify by AAPC.
29.
O13. 3 - Gestational [pregnancy-induced] hypertension without significant proteinuria, third trimester | ICD-10-CM.
O09. 90 - Supervision of high risk pregnancy, unspecified, unspecified trimester. ICD-10-CM.
If there are no complications during the labor or delivery episode, assign code O80, Encounter for full-term uncomplicated delivery. For routine prenatal outpatient visits for patients with high-risk pregnancies, a code from category O09, Supervision of high-risk pregnancy, should be used as the first-listed diagnosis.
Final Character for Trimester. This new ICD-10-CM guideline for the final character indicates that many of the Chapter 15 codes specify the trimester of the pregnancy. A note at the beginning of Chapter 15 defines the timeframes for the three trimesters.
The first known description of the condition was by Hippocrates in the 5th century BC. An outdated medical term for pre-eclampsia is toxemia of pregnancy, a term that originated in the mistaken belief that the condition was caused by toxins.
Although the exact cause of pre-eclampsia is not known, it's thought to occur when there's a problem with the placenta, the organ that links the baby's blood supply to the mother's.
Pregnancy-induced hypertension (PIH) complicates 6-10% of pregnancies. It is defined as systolic blood pressure (SBP) >140 mmHg and diastolic blood pressure (DBP) >90 mmHg. It is classified as mild (SBP 140-149 and DBP 90-99 mmHg), moderate (SBP 150-159 and DBP 100-109 mmHg) and severe (SBP ≥ 160 and DBP ≥ 110 mmHg).
Criteria for hypertension — During pregnancy, hypertension is defined as systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg. Severe hypertension is defined as systolic blood pressure ≥160 mmHg and/or diastolic blood pressure ≥110 mmHg.
Essential (primary) hypertension: I10 That code is I10, Essential (primary) hypertension. As in ICD-9, this code includes “high blood pressure” but does not include elevated blood pressure without a diagnosis of hypertension (that would be ICD-10 code R03. 0).
Different pregnancies come with different conditions that will need to be reported adequately, it is for this reason that any form of Tubal pregnancy will be specified by ICD-10 code 000.1. If a new born is suspected of being affected by mal-presentation before labor, then the condition will be specified by ICD-10 code P01.7.
Z38.1 is an ICD-10 code that has been mandated with the responsibility of reporting any single live born infant that is born outside the hospital. There are situations where a mother might continue to use alcohol during the periods leading to child birth, during this period a baby may be affected by alcohol.
Any pregnancy with a form of abortive outcome will be specified by codes 000-008 depending on the cause of the abortion while 009 will be used to specify any high risk pregnancy. Other ICD 10 codes for pregnancy worth noting include:
The Pregnancy ICD 10 code belong to the Chapter 15 – Pregnancy, Childbirth, and the Puerperium of the ICD-10-CM and these codes take sequencing priority over all the other chapter codes.
Ectopic pregnancy (Code range- O00.00 – O00.91) – This is a potentially life-threatening condition in which the fertilize egg is implanted outside the uterus, usually in one of the fallopian tubes or occasionally in the abdomen or ovaries.
Galactorrhea. Other obstetric conditions, not elsewhere classified (Code range O94-O9A) Sequelae (Late effects) of complication of pregnancy, childbirth, and the puerperium (O94)- Includes conditions or late effects that may occur any time after the puerperium.
Morbidly adherent placenta (Placenta accrete, Placenta increta, Placenta percreta) Placental infarction. Placenta previa (Code range O44.00- O44.53)- Condition in which the placenta is implanted in the lower parts of the uterus.
Having a history of infertility, ectopic or molar pregnancies. Having a history of prior complicated pregnancy or pregnancies resulting in a pre-term delivery or a child with a genetic problem. Having a history of an in-utero procedure during previous pregnancy. Having social problems that is a threat to pregnancy.
Hydatidiform mole (Code range- O01.0 – O01.9) – Also known as molar pregnancy is an abnormal fertilized egg or a non-cancerous tumor of the placental tissue which mimics a normal pregnancy initially but later leads to vaginal bleeding along with severe nausea and vomiting.
If the provider has documented that the pregnancy is incidental to the visit, which means that the reason for the visit was not pregnancy related and the provider did not care for the pregnancy, the code to be used is Z33.1, Pregnant state, incidental and not the chapter 15 codes.
