Symptoms of preeclampsia include:
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.
Chronic hypertension (CHTN) is diagnosed when there is a persistent elevation of blood pressure, which may be diagnosed prior to 20 weeks of pregnancy or may have been diagnosed prior to pregnancy.
ICD-10 code O10 for Pre-existing hypertension complicating pregnancy, childbirth and the puerperium is a medical classification as listed by WHO under the range - Pregnancy, childbirth and the puerperium .
Exploring ICD-10-CM's Chapter 15: Pregnancy, Childbirth & the Puerperium.
Table 1. The number of patients with hypertensive disease in pregnancy was significantly greater in pregnancy when taking into account a personal history of hypertension in pregnancy (14.5% vs. 2.2%), a personal history of chronic hypertension (5.3% vs. 1.0%), a history of paternal hypertension (17.8% vs.
The elevated blood pressure is mild and typically occurs in the later stages of pregnancy. Gestational hypertension can lead to preeclampsia. Assign code 642.3x for gestational hypertension. Code 642.3x also includes documentation of transient hypertension in pregnancy and pregnancy-induced hypertension.
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).
Should the provider document that the pregnancy is incidental to the encounter, then code Z33. 1, Pregnant state, incidental, should be used in place of any chapter 15 codes. It is the providers responsibility to state that the condition being treated is not affecting the pregnancy.
Z33. 1 (Pregnant state, incidental) O09. 90 (supervision of high risk pregnancy, unspecified, unspecified trimester)
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 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.
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.
If the patient is admitted with a pregnancy complication which necessitated a Cesarean delivery, the code for the complication should be sequenced first. But if the reason for admission was different from the reason for the C-section, the reason for the admission will be sequenced first.
Just like in non-obstetric cases, coding for pre-existing hypertensive heart disease and kidney disease in pregnancy requires some extra care because you have to identify the type of heart or kidney disease. Check out these subcategories and the “use additional code” notes that accompany them:
Pre-existing hypertension complicating pregnancy, childbirth and the puerperium and O11. – Pre-existing hypertension with pre-eclampsia are both specific to pre-existing hypertension. Term tips: Pre-existing means that the mother had the condition prior to pregnancy. If you like sources for your terms, you’ll find that definition ...
Hypertension is a common diagnosis, so a lot of specialties have to understand the rules for coding this condition. Obstetrics coders have to go one step further for hypertension and learn the specific rules for coding pre-existing hypertension in pregnancy, which is our focus today.
