What fibromyalgia ICD codes can I use?

If you’re looking for fibromyalgia ICD codes to use, we’d like you to know there are only two ICD-10 codes that are related to it, one being specific to it. Here they are:

  1. M79.7 - Fibromyalgia: This ICD-10 code is meant to be used on a patient confirmed to have Fibromyalgia. This is the only ICD-10 code specific to this condition, so this should be your go-to when dealing with patients with it.
  2. Z82.69 - Family history of other musculoskeletal systems and connective tissue diseases: This ICD-10 code is meant to be used on a patient confirmed to have a family history of specific musculoskeletal systems and connective tissue conditions. Fibromyalgia falls under this, so if your patient has a family history of Fibromyalgia, you can use this. Do note that this is not valid as a principal diagnosis and should only be used to explain the possibility of why a patient has Fibromyalgia.

Are both of these fibromyalgia ICD codes billable?

Yes. Both of these fibromyalgia-related ICD-10 codes are valid and billable.

Clinical information about Fibromyalgia:

Fibromyalgia is a mysterious condition. It is mysterious because healthcare professionals don't exactly know why it occurs. Still, research suggests that it emerges sometime after a person undergoes a surgical procedure if they suffer physical trauma, have an infection, or are constantly and extremely stressed (especially if they are psychologically distressed).

If a patient comes from a lineage of people who have had Fibromyalgia, they're at risk of having it at a certain point in their lives.

A person with Fibromyalgia will likely have the following symptoms:

  • They will feel exhausted even if they haven't done anything strenuous
  • They will feel pain and tenderness in their muscles in various parts of their body
  • They will become prone to headaches, migraines, and even brain fog
  • They might have trouble having restful sleep
  • They might develop anxiety and depression
  • They might have issues with bladder control and might become constipated

Synonyms include:

  • Fibromyalgia
  • Fibromyositis
  • Fibrositis
  • Fibrositis and nodular fasciitis
  • Fibrositis arm
  • Fibrositis of neck
  • Primary fibromyalgia syndrome
  • Primary fibrositis
  • Scapulohumeral fibrositis
  • Secondary fibrositis

Commonly asked questions

No. The ones we mentioned earlier are the only ones for now.

How do healthcare professionals detect/diagnose Fibromyalgia?

There are no official tests for Fibromyalgia, given that no definite cause exists. Healthcare professionals will conduct physical examinations and ask about a person's family and medical history. They might also conduct tests to detect other problems that cause fatigue to rule things out.

How is Fibromyalgia treated?

Fibromyalgia can't be cured, only managed. Proposed ways of working it include using over-the-counter pain medication, exercising, taking medication for anxiety and depression, and taking therapy (CBT and sleep therapy are common).
