About coding sleep disorder

The ICD-10-CM code for sleep disorder is G47.9 (Sleep disorder, unspecified). The official index lists 78 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G47.9.

Within G47, choose G47.9 (Sleep disorder, unspecified) only when documentation doesn't support a more specific option: insomnia (G47.0), hypersomnia (G47.1), circadian rhythm sleep disorders (G47.2), sleep apnea (G47.3), Narcolepsy and cataplexy (G47.4), parasomnia (G47.5), sleep related movement disorders (G47.6) and other sleep disorders (G47.8).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 887 (Other Mental Disorder Diagnoses, relative weight 1.1139), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
