G47.6Sleep related movement disorders

G47.6 is the ICD-10-CM diagnosis code for sleep related movement disorders. It belongs to category G47 (sleep disorders), block G40-G47 (episodic and paroxysmal disorders) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within G47 (sleep disorders), G47.6 is specifically for sleep related movement disorders. Related codes cover insomnia (G47.0), hypersomnia (G47.1), circadian rhythm sleep disorders (G47.2), sleep apnea (G47.3), Narcolepsy and cataplexy (G47.4), parasomnia (G47.5), other sleep disorders (G47.8) and sleep disorder, unspecified (G47.9).

To report this condition, pick the subcode that matches the documentation: G47.61 (disorder), G47.62 (cramps), G47.63 (bruxism) and G47.69 (disorders).

The conditions in its Excludes2 note aren't part of G47.6, but may be coded alongside it if the patient has both: restless legs syndrome (G25.81).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
