  • F51.0 Insomnia not due to a substance or known physiological condition (also a header)
  • F51.1 Hypersomnia not due to a substance or known physiological condition (also a header)
  • F51.3 Sleepwalking [somnambulism]
  • F51.4 Sleep terrors [night terrors]
  • F51.5 Nightmare disorder
  • F51.8 Other sleep disorders not due to a substance or known physiological condition
  • F51.9 Sleep disorder not due to a substance or known physiological condition, unspecified
