Valid for Submission
K64.5 is a billable diagnosis code used to specify a medical diagnosis of perianal venous thrombosis. The code K64.5 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code K64.5 might also be used to specify conditions or terms like external hemorrhoids, hematoma of perianal region, thrombosed external hemorrhoids, thrombosed hemorrhoid incised, thrombosed hemorrhoids , thrombosed internal hemorrhoids, etc.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code K64.5:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- External hemorrhoids with thrombosis
- Perianal hematoma
- Thrombosed hemorrhoids NOS
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code K64.5 are found in the index:
- - Hematoma (traumatic) (skin surface intact) - See Also: Contusion;
- - perianal (nontraumatic) - K64.5
- - Hemorrhoids (bleeding) (without mention of degree) - K64.9
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- External hemorrhoids
- Hematoma of perianal region
- Thrombosed external hemorrhoids
- Thrombosed hemorrhoid incised
- Thrombosed hemorrhoids
- Thrombosed internal hemorrhoids
Diagnostic Related Groups - MS-DRG Mapping
|MS-DRG||MS-DRG Title||MCD||Relative Weight|

|394||OTHER DIGESTIVE SYSTEM DIAGNOSES WITH CC||06||0.9386|
|395||OTHER DIGESTIVE SYSTEM DIAGNOSES WITHOUT CC/MCC||06||0.6497|
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert K64.5 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code K64.5 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
The anus is the opening of the rectum through which stool passes out of your body. Problems with the anus are common. They include hemorrhoids, abscesses, fissures (cracks), and cancer.
You may be embarrassed to talk about your anal troubles. But it is important to let your doctor know, especially if you have pain or bleeding. The more details you can give about your problem, the better your doctor will be able to help you. Treatments vary depending on the particular problem.

What is a blood clot?
A blood clot is mass of blood that forms when platelets, proteins, and cells in the blood stick together. When you get hurt, your body forms a blood clot to stop the bleeding. After the bleeding stops and healing takes place, your body usually breaks down and removes the blood clot. But sometimes the blood clots form where they shouldn't, your body makes too many blood clots or abnormal blood clots, or the blood clots don't break down like they should. These blood clots can be dangerous and may cause other health problems.
Blood clots can form in, or travel to, the blood vessels in the limbs, lungs, brain, heart, and kidneys. The types of problems blood clots can cause will depend on where they are:
- Deep vein thrombosis (DVT) is a blood clot in a deep vein, usually in the lower leg, thigh, or pelvis. It can block a vein and cause damage to your leg.
- A pulmonary embolism can happen when a DVT breaks off and travels through the bloodstream to the lungs. It can damage your lungs and prevent your other organs from getting enough oxygen.
- Cerebral venous sinus thrombosis (CVST) is a rare blood clot in the venous sinuses in your brain. Normally the venous sinuses drain blood from your brain. CVST blocks the blood from draining and can cause a hemorrhagic stroke.
- Blood clots in other parts of the body can cause problems such as an ischemic stroke, a heart attack, kidney problems, kidney failure, and pregnancy-related problems.
Who is at risk for blood clots?
Certain factors can raise the risk of blood clots:
- Atrial fibrillation
- Cancer and cancer treatments
- Certain genetic disorders
- Certain surgeries
- Family history of blood clots
- Overweight and obesity
- Pregnancy and giving birth
- Serious injuries
- Some medicines, including birth control pills
- Staying in one position for a long time, such as being in the hospital or taking a long car or plane ride
What are the symptoms of blood clots?
The symptoms for blood clots can be different, depending on where the blood clot is:
- In the abdomen: Abdominal pain, nausea and vomiting
- In an arm or leg: Sudden or gradual pain, swelling, tenderness, and warmth
- In the lungs: Shortness of breath, pain with deep breathing, rapid breathing, and increased heart rate
- In the brain: Trouble speaking, vision problems, seizures, weakness on one side of the body, and sudden severe headache
- In the heart: Chest pain, sweating, shortness of breath, and pain in the left arm
How are blood clots diagnosed?
Your health care provider may use many tools to diagnose blood clots:
- A physical exam
- A medical history
- Blood tests, including a D-dimer test
- Imaging tests, such as
- X-rays of the veins (venography) or blood vessels (angiography) that are taken after you get an injection of special dye. The dye shows up on the x-ray and allows the provider to see how the blood flows.
- CT Scan
What are the treatments for blood clots?
Treatments for blood clots depend on where the blood clot is located and how severe it is. Treatments may include
- Blood thinners
- Other medicines, including thrombolytics. Thrombolytics are medicines which dissolve blood clots. They are usually used where the blood clots are severe.
- Surgery and other procedures to remove the blood clots
Can blood clots be prevented?
You may be able to help prevent blood clots by
- Moving around as soon as possible after having been confined to your bed, such as after surgery, illness, or injury
- Getting up and moving around every few hours when you have to sit for long periods of time, for example if you are on a long flight or car trip
- Regular physical activity
- Not smoking
- Staying at a healthy weight
Some people at high risk may need to take blood thinners to prevent blood clots.
