ICD 10 Code For Syncope

ICD 10 code for syncope

Introducing the ICD 10 code for syncope

Firstly, syncope is a short-term loss that a person becomes unconscious. Generally, it has a  relation to low circulation of blood to his brain. Also, its other name is passing out or fainting. This problem happens mostly during low blood pressure. Besides, it occurs when the heart cannot pump the blood ideally and cannot pass oxygen to the brain. These are the main symptom and reasons for syncope. So, the doctors use the hospital discharge analyses to determine syncope issues in clinical studies. However, there were no valid studies on the International Classification of Diseases (ICD). It was in 1994. Besides, it was the 10th review (ICD 10 code for syncope) of discharge diagnosis.

The code of syncope in the coding system of ICD-10 is R55.9. There will be some patients who have syncope. Also, they may have the underlying inclining disorder. They may have the classification of discharge diagnosis. Besides, these patients face syncope because of myocardial infarction, aortic stenosis, ventricular tachycardia, etc. Potential programs for syncope are not much common. These programs are initially much costly. Besides, the administration needs a vast source of data. They need the data for observation, evaluation, and assessment of the disease and its outcome. However, the databases of the administration are highly beneficial. The admin combines these databases with other databases, and they become rich in their contents and sizes.

ICD 10 code for syncope – Types of Syncope

There are different kinds of syncope. However, it depends on the causes of the problem.

Vasovagal syncope

The other name of vasovagal syncope is cardio-neurogenic syncope. It is a common syncope. The sudden fall in blood pressure causes this problem. Besides, it causes problems in to flow of blood to the brain. The gravity roots the settlement in the blood in the lower portion of the body during stand-up. That time, the nervous system and heart work together to have stability at blood pressure. Besides, some patients of this syncope face the condition of orthostatic hypotension. Also, it stops the blood vessels from being smaller. This situation happens during the standing position of the patient.

Situational syncope

Situational syncope is one kind of special vasovagal syncope. It affects the nervous system. The situations due to this problem are here,

  • Deep emotional stress
  • Fear
  • Pain
  • Anxiety
  • Hunger
  • Dehydration
  • Use of drugs or alcohol.
  • A person breathes extreme oxygen—also, quick release of much carbon dioxide.
  • Forceful coughing.
  • Urinating

Postural syncope

Its other name is postural hypotension. Sometimes, blood pressure drops suddenly. But, it happens due to the fast-changing of position, for example, sitting to standing. This state causes postural syncope. However, some medicines and high dehydration cause this condition.

The bad condition of the blood vessel or heart affects the blood circulation towards the brain. Besides, this situation causes Cardiac syncope. This condition causes arrhythmia. Also, it makes a blockage in average blood circulation. So, visit a doctor if you face cardiac syncope as it is risky and causes sudden death.

Neurologic syncope

You may face some bad neurological situations like stroke or seizure. But, these conditions cause neurologic syncope. Besides, there are some other less familiar conditions. They are the normal pressure hydrocephalus and migraines. Also, they cause this kind of syncope.

Postural Orthostatic Tachycardia Syndrome

Massive heart rate is the main reason for this disease. The other name of fast heart rate is tachycardia. However, it occurs during the immediate position changing of a person. The increase in heart rate usually happens within only 10 minutes of standing position. Women are primarily familiar with this problem. Also, men can face this problem.

ICD 10 code for syncope – symptoms of syncope

Syncope’s typical symptoms are here,

  • Firstly, the patient will feel lightheaded.
  • He may fall without any reason.
  • Besides, he may feel dizzy and tired.
  • He will face fainting after physical exercise or eating.
  • Also, the patient may feel weak and unsteady during standing.
  • Sometimes, he will have a severe headache.
  • Besides, His vision may have a slight change.

Sometimes, syncope turns into a more severe condition. So, it is essential to visit a doctor and take treatment after facing the symptoms of syncope. But, in most cases, the patients can get prevention after getting a correct diagnosis and treatment.

ICD 10 code for syncope – causes of syncope

Many things can cause syncope. Most of the patients have medical conditions that they do not know their effects. Besides, these conditions hamper the heart and the nervous system. Also, you may have some other states like a sudden change of positions. It drops the blood pressure suddenly. Besides, it has a massive effect on the typical blood circulation system of the body.

ICD 10 code for syncope – Diagnosis process of syncope

Visit your doctor if you have syncope. He can check your condition. Besides, he may refer to a specialist of syncope to have a complete checkup. The doctor may evaluate the physical test and your medical history. Also, he may ask some detailed questions. These questions will be on the symptoms and episodes of syncope. Besides, he may ask if you faced this problem before or not. Also, he will ask the time and place of the occurrence of this disease. It will help the doctor to prescribe you ideally.

Besides, the doctor will give some more physical tests to determine the reasons. These tests may check the heart rate, blood circulation process, and the nervous system of the patient’s body.

Tests to determine causes of syncope

There are different tests to determine the conditions and reasons for syncope. Here are some of them.

Laboratory testing

Firstly, test the blood to check for metabolic changes or anemia.

Electrocardiogram (ECG or EKG)

ECG records the heart’s electrical activity. Doctors use electrodes to the skin to collect data.

Exercise stress test

The exercise stress test uses ECG records to examine the electrical activity of the heart during being active. A stationary bike or treadmill helps to get the targeted heart rate.


An echocardiogram or echo is an exam that uses high-frequency sound waves to create the heart structures’ image.

Tilt table

The doctors use a tilt table in different stages of this test. Besides, it keeps the records of heart rate and blood pressure of each minute and heartbeat. Also, it shows the abnormality of cardiovascular reflection. This reflection mainly causes syncope.

Blood volume determination

This test checks the amount of blood to justify if the amount is enough or not. This amount varies with gender, weight, and height. Besides, the doctors inject a small radioactive tracer through the intravenous line. They place this line in the patient’s vein in the arm. Also, they take blood as a sample and analyze it in the lab. There is a system to analyze blood. However, it gives an accurate result within half an hour. Its name is the blood volume analyzer system.

Hemodynamic testing

This test checks the flow rate of blood. Also, it prevents pressure inside the blood vessels. The doctors measure it during the contraction of the heart muscle. Thus they pump enough blood into the body. A radioactive tracer helps to get three sets of pictures for analyzing the condition.

ICD 10 code for syncope – methods

Suppose there is an investigation for a group of syncope patients. Firstly, the doctors have examined two samples. The first sample contains 5262 random medical patients. Besides, the other one consists of 750 patients. These 750 patients are from the emergency department. The doctors admitted them to three hospitals in Denmark for syncope. The ICD 10 code for syncope is R55.9. They reviewed all the charts to get the baseline features. Besides, this analysis confirms the presence or absence of syncope. Also, they compare this coding with the coding from the administration.

Moreover, there were 600 patients. Among them, 570 patients, which means 95% of them had syncope. Besides, among another group of 150 patients, 140 patients had positive projection values. The median age of the patients was 70 years.

Finally, in the second sample, there were 5262 random patients. Among them, 75 patients were suffering from syncope. Among these 75 people, 47 had the ICD-10 code, and the code was R55.9.

ICD 10 code for syncope – Results

There was a review of 750 charts from different patients. The code of the syncope was R55.9. It was about 150 ED charts. Besides, there were charts from 600 patients. The analyzers revealed 570 and 140 cases.

Similarly, those cases fulfilled the criteria of syncope. Besides, the administration had code with a higher computed positive value. The positive predicted value was 95% in hospitalized patients and 93% in an ED. All the patients were from three different hospitals in Denmark. Besides, the median age was 70 years. Also, the interquartile range was between 53 to 81 years. About 48% of these patients were women. These 570 patients had different diseases and physical problems. 51% had high blood pressure, 22% had heart diseases, and 11% were suffering from heart failure problems. Also, 10% were with diabetes background, and 14% had atrial fibrillation. There was no significant difference between the patients from these three hospitals.

Moreover, the doctors computed the sensitivity by the valid value of the revealed sample. The negative value of prediction was about 99%. Besides, two reviewers reviewed the result blindly. There was no difference.

ICD 10 code for syncope – the treatment options

The treatment options may depend on the reasons, tests, evaluation, and results of the syncope. Besides, the doctors have goals for their treatments. Also, they try to keep you out of danger. The treatment options are,

  • Firstly, take medicines or change the past medications that you already are taking.
  • Improve blood circulation by wearing extra garments for support. Besides, you can use tight leggings to improve your blood circulation.
  • Bring some changes to your food habit. The doctor may give suggestions for your diet. Try to eat frequent and small meals. Besides, eat more salty food, and drink more liquids. Also, take much amount of potassium, and avoid alcohol and caffeine.
  • During stand-up from sitting, be alert enough.
  • Besides, use an extra pillow or your hand for comfortable and sound sleeping.
  • Change or avoid the states that are the causes of syncope.
  • Also, take some training and exercises for a fast and steady heartbeat.
  • Go to the doctor to take some treatments for primary heart disease.
  • A pacemaker may keep the heart rate sound and regular. But, patients with some specific medical conditions may need it. If you have those medical conditions, implement them with the help of a doctor.
  • ICD is a device that constantly monitors the heart rhythm and the rate. Also, it corrects an abnormal rhythm.
  • Finally, the doctor and other members of the medical team may make a plan for your treatment. Try to follow them.

Try to keep in touch with doctors and follow their instructions. You have no other options except to follow them.

Wrapping up with ICD 10 code for syncope

In conclusion, the identification of the ICD 10 code is precise for the admitted patients in the hospital. The doctors can use the code R55.9  for an optimistic prediction. The prediction rate is 95%. Besides, the sensitivity is 63%. But, for a more accurate result, you need to collect more data from patients. Some recent analysis has shown that the present episodes of syncope are higher in number. This situation is because of a reduction in quality of life. However, it is valid for both young and adults. Besides, studies on functional capacity and work loss have shown a better result and relationship with this disease’s symptoms.
