What is fibromyalgia?

Fibromyalgia is a chronic disorder characterized by widespread musculoskeletal pain, fatigue, and tenderness in localized areas of the body. It is a common condition affecting millions of people worldwide, and it is more prevalent in women than men.

There is no known cure for fibromyalgia, but treatment options may include medication, physical therapy, exercise, and stress management techniques. A multidisciplinary approach to treatment is often recommended, including a combination of lifestyle changes, medication, and psychological therapy.

What is fibromyalgia

How is fibromyalgia diagnosed?

In order to be diagnosed with fibromyalgia, a person must have had chronic pain for at least three months. The pain must also be widespread, affecting both sides of the body and the upper and lower body. In addition, the pain must be accompanied by at least one other symptom, such as fatigue, difficulty sleeping, or memory problems.

A doctor assigns the code after a patient has undergone a complete medical evaluation. The evaluation must rule out other possible causes of the symptoms, such as arthritis or a spinal injury.

In other words, a disorder where a patient suffers chronic pain and stiffness all over his body. Chronic disease affects both genders regardless of age and location, but it is mostly found in women. The main purpose of fibromyalgia is a lack of physical activity or exposure to not suitable weather conditions. The suffering is also called fibromyalgia syndrome.

Some other fibromyalgia symptoms include;

  • Trouble in sleeping
  • Fatigue
  • Headache
  • Sleeping for a long time without feeling fresh
  • Dry eyes
  • Mood disorders
  • Bladder disorders

People with fibromyalgia usually feel constant pain as their brain continuously multiplies pain signals. Practitioners diagnose this disorder as a primary or secondary cause of fibromyalgia.

To cure the pain and diagnose the disease efficiently, it becomes necessary for the patient to visit multiple doctors until fibromyalgia gets diagnosed. The process of diagnosing fibromyalgia can be frustrating for patients as there is no direct test that diagnoses fibromyalgia from the first exposure because the core symptoms that the patient may feel can be the reason for any other disease as well.

Hence, it becomes mandatory for physicians to determine the cause of symptoms and diagnose fibromyalgia by checking the whole checklist of tests and symptoms for the disease. For this wide process of diagnosis of fibromyalgia, certain tools are there that providers use for the purpose;

  • Complete physical examination
  • Blood tests and radiology tests to identify other conditions.
  • Access to medical history that may identify the whole symptoms of the disease

Diagnosis Code for Fibromyalgia

To proper diagnosis of fibromyalgia, the requirement from A to B must be fulfilled;

  • A – Persistent suffering from pain (equal to or more than three months) not limited to one part of the body
  • B.1 – Chronic pain is becoming the reason for emotional distress
  • B.2 – Due to pain, the activities of a normal life are hindered, and pain interferes with social participation.
  • C – The pain causes sleep disorder, and somatic symptoms, and is associated with cognitive dysfunction
  • D – Another chronic condition may trigger the pain

Part D of the above-mentioned reports are there that the conditions such as;

  • Injury
  • Surgery
  • Infection
  • Emotional stress

It can trigger chronic disease at any time. As mentioned earlier that fibromyalgia can happen to anyone regardless of gender, but it commonly occurs in;

  • Adults
  • Women – because they have a higher tendency to grow fibromyalgia
  • Individuals with a family history of fibromyalgia
  • Individuals with the health condition like lupus, rheumatoid arthritis, or ankylosing spondylitis

However, the treatment for fibromyalgia involves strategies to implement for self-care and medication. The medication that is used in fibromyalgia treatment include;

Antidepressants – Milnacipran (Savella) and Duloxetine (Cymbalta) are two depressants that are widely used to treat fibromyalgia as they help in fatigue and pain relief associated with the chronic disease. In order to promote sleep, physicians may also prescribe muscle relaxants cyclobenzaprine or amitriptyline.

Pain Relievers – Over-the-counter like ibuprofen (Advil, Motrin IB, others), acetaminophen (Tylenol, others), or naproxen sodium (Aleve, others) would be significantly helpful in managing fibromyalgia. Plus, physicians do not suggest opioids because they lead to significant dependence and side effects that worsen the suffering with time.

Anticonvulsants – Many other types of pain such as epilepsy are treated using medication and their outcomes are considerable for all pain types. Gabapentin (Neurontin) can also be helpful in the reduction of pain caused by fibromyalgia and minimize the symptoms. Besides, the first drug that the United States Food and Drug Administration approved to use in the treatment of fibromyalgia was pregabalin (Lyrica).

Some other treatments include;

  • Occupational therapy
  • Physical therapy
  • Counseling

The book also provides codes for tissue disorder which lies in the category M70-M79, these codes are used in the claims for other soft tissue issues and disorders.

M79.9, not only limits itself to fibromyalgia but can also be used for other health conditions such as fibrositis, fibromyositis, nodular fasciitis, nodular fasciitis, fibrositis of the neck, and fibrositis arm.

Ending note

Fibromyalgia reports are surging because the symptoms of fibromyalgia are also connected to other diseases. This is why while using diagnosis codes for fibromyalgia, there’s a dire need of understanding every code to reduce the chances of claim denials. Hiring a chiropractic billing service would be a great option to ensure this doesn’t happen. Plus, outsourcing your revenue process to experts will ease your burden to a great extent.
