Valid for Submission
O22.50 is a billable diagnosis code used to specify a medical diagnosis of cerebral venous thrombosis in pregnancy, unspecified trimester. The code O22.50 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code O22.50 might also be used to specify conditions or terms like cerebral venous thrombosis in pregnancy, cerebral venous thrombosis of pregnancy and/or puerperium, obstetric cerebral venous thrombosis or thrombosis of intracranial venous sinus of pregnancy and/or puerperium.
The code O22.50 is applicable to female patients aged 12 through 55 years inclusive. It is clinically and virtually impossible to use this code on a non-female patient outside the stated age range.
Unspecified diagnosis codes like O22.50 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Cerebral venous thrombosis in pregnancy
- Cerebral venous thrombosis of pregnancy AND/OR puerperium
- Obstetric cerebral venous thrombosis
- Thrombosis of intracranial venous sinus of pregnancy AND/OR puerperium

Convert O22.50 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code O22.50 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Health Problems in Pregnancy
Every pregnancy has some risk of problems. You may have problems because of a health condition you had before you got pregnant. You could also develop a condition during pregnancy. Other causes of problems during pregnancy can include being pregnant with more than one baby, a health problem in a previous pregnancy, substance abuse during pregnancy, or being over age 35. Any of these can affect your health, the health of your baby, or both.
If you have a chronic condition, you should talk to your health care provider about how to minimize your risk before you get pregnant. Once you are pregnant, you may need a health care team to monitor your pregnancy. Some common conditions that can complicate a pregnancy include
- High blood pressure
- Polycystic ovary syndrome
- Kidney problems
- Autoimmune disorders
Other conditions that can make pregnancy risky can happen while you are pregnant - for example, gestational diabetes and Rh incompatibility. Good prenatal care can help detect and treat them.
Some discomforts, like nausea, back pain, and fatigue, are common during pregnancy. Sometimes it is hard to know what is normal. Call your health care provider if something is bothering or worrying you.

What is a stroke?
A stroke happens when there is a loss of blood flow to part of the brain. Your brain cells cannot get the oxygen and nutrients they need from blood, and they start to die within a few minutes. This can cause lasting brain damage, long-term disability, or even death.
If you think that you or someone else is having a stroke, call 911 right away. Immediate treatment may save someone's life and increase the chances for successful rehabilitation and recovery.
What are the types of stroke?
There are two types of stroke:
- Ischemic stroke is caused by a blood clot that blocks or plugs a blood vessel in the brain. This is the most common type; about 80 percent of strokes are ischemic.
- Hemorrhagic stroke is caused by a blood vessel that breaks and bleeds into the brain
Another condition that's similar to a stroke is a transient ischemic attack (TIA). It's sometimes called a "mini-stroke." TIAs happen when the blood supply to the brain is blocked for a short time. The damage to the brain cells isn't permanent, but if you have had a TIA, you are at a much higher risk of having a stroke.
Who is at risk for a stroke?
Certain factors can raise your risk of a stroke. The major risk factors include
- High blood pressure. This is the primary risk factor for a stroke.
- Heart diseases. Atrial fibrillation and other heart diseases can cause blood clots that lead to stroke.
- Smoking. When you smoke, you damage your blood vessels and raise your blood pressure.
- A personal or family history of stroke or TIA.
- Age. Your risk of stroke increases as you get older.
- Race and ethnicity. African Americans have a higher risk of stroke.
There are also other factors that are linked to a higher risk of stroke, such as
- Alcohol and illegal drug use
- Not getting enough physical activity
- High cholesterol
- Unhealthy diet
- Having obesity
What are the symptoms of stroke?
The symptoms of stroke often happen quickly. They include
- Sudden numbness or weakness of the face, arm, or leg (especially on one side of the body)
- Sudden confusion, trouble speaking, or understanding speech
- Sudden trouble seeing in one or both eyes
- Sudden difficulty walking, dizziness, loss of balance or coordination
- Sudden severe headache with no known cause
If you think that you or someone else is having a stroke, call 911 right away.
How are strokes diagnosed?
To make a diagnosis, your health care provider will
- Ask about your symptoms and medical history
- Do a physical exam, including a check of
- Your mental alertness
- Your coordination and balance
- Any numbness or weakness in your face, arms, and legs
- Any trouble speaking and seeing clearly
- Run some tests, which may include
- Diagnostic imaging of the brain, such as a CT scan or MRI
- Heart tests, which can help detect heart problems or blood clots that may have led to a stroke. Possible tests include an electrocardiogram (EKG) and an echocardiography.
What are the treatments for stroke?
Treatments for stroke include medicines, surgery, and rehabilitation. Which treatments you get depend on the type of stroke and the stage of treatment. The different stages are
- Acute treatment, to try to stop a stroke while it is happening
- Post-stroke rehabilitation, to overcome the disabilities caused by the stroke
- Prevention, to prevent a first stroke or, if you have already had one, prevent another stroke
Acute treatments for ischemic stroke are usually medicines:
- You may get tPA, (tissue plasminogen activator), a medicine to dissolve the blood clot. You can only get this medicine within 4 hours of when your symptoms started. The sooner you can get it, the better your chance of recovery.
- If you cannot get that medicine, you may get medicine that helps stop platelets from clumping together to form blood clots. Or you may get a blood thinner to keep existing clots from getting bigger.
- If you have carotid artery disease, you may also need a procedure to open your blocked carotid artery
Acute treatments for hemorrhagic stroke focus on stopping the bleeding. The first step is to find the cause of bleeding in the brain. The next step is to control it:
- If high blood pressure is the cause of bleeding, you may be given blood pressure medicines.
- If an aneurysm if the cause, you may need aneurysm clipping or coil embolization. These are surgeries to prevent further leaking of blood from the aneurysm. It also can help prevent the aneurysm from bursting again.
- If an arteriovenous malformation (AVM) is the cause of a stroke, you may need an AVM repair. An AVM is a tangle of faulty arteries and veins that can rupture within the brain. An AVM repair may be done through
- Injecting a substance into the blood vessels of the AVM to block blood flow
- Radiation to shrink the blood vessels of the AVM
Stroke rehabilitation can help you relearn skills you lost because of the damage. The goal is to help you become as independent as possible and to have the best possible quality of life.
Prevention of another stroke is also important, since having a stroke increases the risk of getting another one. Prevention may include heart-healthy lifestyle changes and medicines.
Can strokes be prevented?
If you have already had a stroke or are at risk of having a stroke, you can make some heart-healthy lifestyle changes to try to prevent a future stroke:
- Eating a heart-healthy diet
- Aiming for a healthy weight
- Managing stress
- Getting regular physical activity
- Quitting smoking
- Managing your blood pressure and cholesterol levels
If these changes aren't enough, you may need medicine to control your risk factors.
