Avoid Unspecified Codes for Sleep Disorders
Question: I-m having a hard time understanding the new ICD-9 sleep codes beginning with 327. When should I be using these codes instead of the old 780.5 series? Answer: With the addition of the new organic sleep disorder category, the sleep disturbance codes 780.51-780.59 were all changed to indicate unspecified diagnoses. Rule of thumb: One big source of confusion comes from understanding the definition of an -organic- sleep disorder. To gain some clarity on this term, it is probably easiest to remember what organic disorders don't include, namely emotional or drug/alcohol-induced causes.

You should only use the 780.5x series of codes if the following, more specific, classifications are not appropriate:
- Nonorganic sleep disorders (307.40-307.49)
- Circadian rhythm sleep disorders (327.30-327.39)
- Organic insomnia (327.00-327.09)
- Organic hypersomnia (327.10-327.19)
- Organic sleep apnea (327.20-327.29)
- Parasomnias (327.40-327.49)
- Organic sleep-related movement disorders (327.51-327.59)
- Alcohol- or drug-induced disorders (291.82, 292.85)
- Restless leg syndrome (333.99).
When using the new sleep diagnoses, you also need to be careful of the sequencing. You-ll order the organic sleep disorder code as secondary whenever you are reporting a diagnosis resulting from other mental or medical conditions.
Example: A patient with paraphrenia (297.2) presents for sleep testing after experiencing insomnia. You would use 297.2 as your primary diagnosis, followed by 327.02 (Insomnia due to mental disorder).
