G47.33 Replaces 327.23 Under ICD-10-CM

When ICD-10 codes go into effect, similar functioning code in the I-10 G Suffix replaces 327.23.

In order to diagnose obstructive sleep apnea (OSA), an otolaryngologist will provide a complete inspection of the nose, mouth, throat, palate and neck, many a time using a fiberoptic scope. Right now, you would code 327.23 for patients suffering from OSA.

Difference in ICD-10 coding: So now under ICD-9-CM code set, when a patient gets diagnosed with obstructive sleep apnea, you will go for 327.23. However after a couple of years, when ICD-10 goes into effect, this code will become G47.33. This change to ICD-10 will not offer any difference. As a matter of fact, G47.33's descriptor is a carbon copy depiction of ICD-9's 327.23.

While diagnosing a sleep disorder such as OSA, a physician may have the patient fill up a questionnaire in order to obtain information on patterns of wake-sleep. That apart, she may also order blood tests to rule out other conditions. If the physician suspects a sleep disorder, the patient would most likely go through a polysomnography to record breathing and brain and muscle during sleep. Treatment will depend on the specific type of disorder, and if there's an underlying cause.

ICD-10 tips: One of the ways an otolaryngologist can lessen this potentially life-threatening condition is with genioglossus advancement. This procedure involves the surgeon creating a small bone window in front of the lower jaw, and then pulls the tendons that fix the front of the tongue to the jaw forward onto a bone fragment. This leads to a larger airway between the back of the tongue and the throat, and results in easier breathing for obstructive sleep apnea patients.

You would code mandibular segmental osteotomy with genioglossus advancement with 21199 when carried out to treat obstructive sleep apnea.
