Diagnosis Code R94.131

ICD-10: R94.131
Short Description: Abnormal electromyogram [EMG]
Long Description: Abnormal electromyogram [EMG]
This is the 2019 version of the ICD-10-CM diagnosis code R94.131

Valid for Submission
The code R94.131 is valid for submission for HIPAA-covered transactions.

Code Classification
  • Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00–R99)
    • Abnormal findings on diagnostic imaging and in function studies, without diagnosis (R90-R94)
      • Abnormal results of function studies (R94)

Information for Medical Professionals

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.
Diagnostic Related Groups

Information for Patients


Muscle Disorders

Also called: Myopathy

Your muscles help you move and help your body work. Different types of muscles have different jobs. There are many problems that can affect muscles. Muscle disorders can cause weakness, pain or even paralysis.

Causes of muscle disorders include

  • Injury or overuse, such as sprains or strains, cramps or tendinitis
  • A genetic disorder, such as muscular dystrophy
  • Some cancers
  • Inflammation, such as myositis
  • Diseases of nerves that affect muscles
  • Infections
  • Certain medicines

Sometimes the cause is not known.
