2025 ICD-10-CM code M79.12

Myalgia of auxiliary muscles, head and neck.

Use M79.12 when the myalgia is specifically located in the auxiliary muscles of the head and neck. Do not use this code for myalgia of the mastication muscles (M79.11) or other sites (M79.18).

Medical necessity is established by the presence of myalgia and associated functional limitations. Treatment should aim to alleviate pain and restore function.

Diagnosis is based on patient history, physical examination, and palpation of affected muscles to identify trigger points. Treatment may include physical therapy, massage, analgesics, muscle relaxants, NSAIDs, and trigger point injections.

In simple words: Muscle pain in the neck and head muscles that help with movement, often caused by strain, overuse, or stress.

Muscle pain in the auxiliary muscles of the head and neck, often associated with myofascial pain syndrome. This pain typically arises from muscle injury due to excessive strain, repetitive motions, or stress.

Example 1: A patient presents with neck pain after sleeping in an awkward position. Upon examination, trigger points are found in the trapezius muscle. The diagnosis is M79.12., A patient reports persistent headaches and pain in the neck muscles due to prolonged computer use. The diagnosis is M79.12., A patient experiences pain and stiffness in the sternocleidomastoid muscle after a whiplash injury. The diagnosis is M79.12.

Documentation should include the location of myalgia, the presence of trigger points, and any associated symptoms.
