G71.11 is a billable ICD code used to specify a diagnosis of myotonic muscular dystrophy. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code G711 is used to code Neuromyotonia

Neuromyotonia (NMT), also known as Isaacs Syndrome and Isaacs-Merton syndrome, is a form of peripheral nerve hyperexcitability that causes spontaneous muscular activity resulting from repetitive motor unit action potentials of peripheral origin. Prevalence is unknown but 100—200 cases have been reported so far.
