ICD-10 Code for Fibromyalgia
The ICD-10 code for fibromyalgia is M79.7 1.
Code Details
The specific code M79.7 was established in the German health system and is recognized internationally for fibromyalgia diagnosis 1.
In the ICD-10 classification system, this code falls under the broader category of "Other soft tissue disorders" (M79), with fibromyalgia designated as M79.7 1, 2.
This code is used for billing, documentation, and tracking of fibromyalgia patients in healthcare systems, and has been validated in large electronic database studies examining healthcare utilization patterns 2.
Clinical Context
Fibromyalgia is recognized as a complex condition characterized by chronic widespread pain, abnormal pain processing, and central sensitization, rather than peripheral tissue damage or inflammation 3.
The diagnosis requires widespread pain in all four quadrants of the body for at least 3 months, plus pain on palpation in at least 11 of 18 specific tender points, according to the American College of Rheumatology criteria 3.
Normal laboratory results support rather than exclude the diagnosis, as there is no organic tissue damage or inflammation in fibromyalgia 3.
