Pinpoint the Organic Sleep Apnea ICD-9 Code

Question: What is organic sleep apnea? My physician has been using 780.57 to report sleep apnea, but ICD-9 revised 780.57 to say "unspecified" and added 327.23. Would you explain the difference to me?

Answer: When your physician indicates "organic sleep apnea," it means he was able to identify a specific cause of the sleep apnea.-
- For example, when the cardiologist determines that excessive weight is producing obstruction of the upper airways, causing the sleep apnea, you would report 327.23 (Obstructive sleep apnea [adult] [pediatric]).
- You would report unspecified sleep apnea (780.57) if your cardiologist is unable to identify the cause of the apnea or is still trying to determine the cause. Except for 780.56 and 780.59, all the 780.5x codes are "unspecified," meaning that you should use them when your physician doesn't give a specific cause for the condition. All the 327.2x codes are "specified" causes of organic sleep apnea, except 327.20 (Organic sleep apnea, unspecified).
