What Myalgia ICD-10 codes can I use?

If you’re looking for Myalgia ICD codes, there are four to pick from:

M79.10 - Myalgia, unspecified site

This ICD-10 code is meant to be used on a patient confirmed to have Myalgia. This code has an unspecified label, which means that the specific location of the Myalgia hasn’t been identified. Once the particular location is determined, you must use a more specific ICD-10 code.

M79.11 - Myalgia of mastication muscle

This ICD-10 code is meant to be used when the Myalgia is confirmed in the mastication muscle.

M79.12 - Myalgia of auxiliary muscles, head and neck

This ICD-10 code is meant to be used when the Myalgia is confirmed in the auxiliary muscles, head, and/or neck.

M79.18 - Myalgia, other site

This ICD-10 code is meant to be used when the Myalgia is confirmed in areas not covered by the preceding ICD-10 codes.

Are these Myalgia ICD-10 codes billable?

Yes. These ICD-10 codes for Myalgia are valid and billable.

Clinical information about Myalgia:

Myalgia is the medical term for muscle pain and discomfort. It could be any kind of pain (e.g., sharp, dull, throbbing, aching) or discomfort, and it can be located in any muscle or muscle group. Cramps and spasms can accompany the pain/discomfort.

Every person will experience Myalgia now and then. It can be caused by the following:

Overexerting oneself during physical activities
Sustaining injuries like sprains, tendinitis, and broken bones
Having infections like influenza and malaria
Having autoimmune diseases like multiple sclerosis and lupus
Being stressed
Taking certain medications that lower cholesterol and treat high blood pressure
Serious conditions like cancer and spinal muscular atrophy

Synonyms include:

Muscle pain
Muscle tension pain
Musculoskeletal pain
Musculoskeletal tenderness
Tenderness at muscle insertion

Commonly asked questions

No, but it’s easy to believe so because they involve muscle pain and discomfort. Fibromyalgia is caused by the central nervous system not processing sensory information properly. Those who have it have a heightened sensitivity to pain, and they also feel fatigued and have trouble sleeping.

Healthcare professionals may conduct blood tests, imaging tests, and muscle biopsies to determine if an underlying condition is causing it.

That depends on what’s causing it. Healthcare professionals will work on addressing conditions that cause Myalgia, but basic treatment includes taking over-the-counter pain relievers, physical therapy, and lifestyle changes.
