I69.842 - Monoplegia of lower limb following other cerebrovascular disease affecting left dominant side

Present on Admission (POA)

I69.842 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Paralysis

Paralysis is the loss of muscle function in part of your body. It happens when something goes wrong with the way messages pass between your brain and muscles. Paralysis can be complete or partial. It can occur on one or both sides of your body. It can also occur in just one area, or it can be widespread. Paralysis of the lower half of your body, including both legs, is called paraplegia. Paralysis of the arms and legs is quadriplegia.

Most paralysis is due to strokes or injuries such as spinal cord injury or a broken neck. Other causes of paralysis include:

• Nerve diseases such as amyotrophic lateral sclerosis
• Autoimmune diseases such as Guillain-Barre syndrome
• Bell's palsy, which affects muscles in the face

Polio used to be a cause of paralysis, but polio no longer occurs in the U.S.

Stroke

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% 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.
• Diabetes.
• 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
  • Surgery
  • 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.
