Fibromyalgia diagnostic code

Fibromyalgia is finally being included as a separate diagnosis in the ICD-10-CM or International Classification of Diseases, 10th Revision, Clinical Modification. Fibromyalgia was previously under the code of 729.1 that stands for myalgia and myositis, unspecified. The World Health Organization (WHO) is responsible for publishing the ICD codes and keeps them updated.


Health advocates have shared that the change is a positive step for patients who suffer from fibromyalgia. This increases the recognition of the disease and gives health providers a clear code to bill insurance. The International Classification of Diseases (ICD) codes are considered the standard and used by hospitals, clinics, doctors, insurance companies and others. M79.7 is now the billable ICD-10-CM code for fibromyalgia. Both the National Center for Health Statistics and the Centers for Medicare and Medicaid Services use the ICD-10-CM.

The International Classification of Diseases (ICD) codes go beyond being useful for insurance billing purposes. They are also used by the World Health Organization and others to monitor the prevalence of certain diseases and analyze the data. The codes are constantly being revised, and ICD-11 will be available in the future.

Before fibromyalgia received its own diagnostic code, doctors were forced to use the 729.1 code that stands for myalgia and myositis, unspecified. This code includes different types of muscle pain and is not specific enough for the disease. However, patients who suffer from fibromyalgia now have their own code for the diagnosis. In the past, some insurance providers did not cover fibromyalgia, so health advocates hope that the new code encourages greater coverage.

Researchers also use the ICD-10-CM and ICD codes to track diseases and categorize their studies. By having a specific code for fibromyalgia, researchers will be able to track the condition easier and make it simpler for patients to follow the latest news.
