What sleep apnea ICD codes can I use?

If you're looking for sleep apnea ICD codes, there are only a few to choose from with sleep apnea in their names. Here are the ones that you can select from:

G47.30 - Sleep apnea, unspecified: This ICD-10 code is used for patients who have been confirmed to have sleep apnea. The unspecified label indicates that the type of sleep apnea is unknown or unidentified. There are several types of sleep apnea, including central sleep apnea, obstructive sleep apnea, and mixed or complex sleep apnea. If you have identified your patient's specific type of sleep apnea, it's best to use a more specific ICD-10 code once the particular type is determined.
G47.31 - Primary central sleep apnea: This ICD-10 code is used for patients who have been confirmed to have primary central sleep apnea. This type of sleep apnea is characterized by a problem with the brain that disrupts its function to send signals to breathing-related muscles.
G47.33 - Obstructive sleep apnea (adult) (pediatric): Coding obstructive sleep apnea, ICD-10 code G47.33, is intended for patients confirmed to have obstructive sleep apnea. A person with this type of sleep apnea is characterized by the relaxation of their head and neck muscles. This is also true for children with pediatric obstructive sleep apnea or child obstructive sleep apnea. When these muscles relax, nearby tissues press on the patient's windpipe, obstructing the airways.
G47.37 - Central sleep apnea in conditions classified elsewhere: This ICD-10 code is intended for use in patients confirmed to have central sleep apnea, specifically those cases caused by other conditions. It's best to check if your patient's condition, obstructive sleep apnea, doesn't have a specific ICD-10 code. You can use this if the condition is caused by specific conditions not covered by certain ICD-10 codes.
G47.39 - Other sleep apnea: This ICD-10 code is intended for use in patients who have been confirmed to have sleep apnea, specifically a type not covered by other ICD-10 codes. You can use this for mixed sleep apnea and organic sleep apnea.
G47.32 - High-altitude periodic breathing: This ICD-10 code is used for patients who have been confirmed to have high-altitude periodic breathing. This type of breathing is unstable and is caused by a reduced oxygen content in a person's blood, resulting from being in a high-altitude location. This type of breathing can result in Central Sleep Apnea.

Are these sleep apnea ICD codes billable?

Yes. All of the ones we listed above are valid and billable.

Clinical information about sleep apnea

Sleep apnea is a kind of sleeping disorder. A patient who has sleep apnea will stop breathing now and then while they sleep. When a person's breathing stops while sleeping, the brain begins sending signals to wake them up. As soon as the person wakes up, their breathing resumes.

The breathing stops due to their airways being blocked or if there's something wrong with the brain's ability to control breathing. If a person keeps waking up because they stop breathing occasionally while sleeping, they won't be able to get enough restful sleep. If they're not getting enough sleep and this problem has been left unmanaged and untreated for too long, it can lead to terrible consequences because this problem can eventually lead to heart problems.

A person with sleep apnea will exhibit/experience the following symptoms:

Insomnia
Hypersomnia (or daytime sleepiness)
They will snore a lot, in some cases loudly
They will have unusual breathing patterns while sleeping
They will likely wake up a lot at night
They will sweat a lot at night and wake up
They will feel tired when they wake up
They will be susceptible to mood changes
They're prone to getting headaches due to lack of restful sleep
They will feel restless and anxious

Synonyms include

Breathing-related sleep disorder
Hypersomnia with sleep apnea
Insomnia with sleep apnea
Central sleep apnea syndrome
Central sleep apnea without Cheyne-Stokes respiration
Primary central sleep apnea
Central sleep apnea caused by high altitude
High altitude periodic breathing
Obstructive sleep apnea of adult
Obstructive sleep apnea of child
Circadian rhythm sleep disorder

Commonly asked questions

There is one, but we don’t recommend using that because it is unbillable and invalid.

Healthcare professionals will conduct a Home Sleep Apnea Test or a Polysomnogram (an overnight sleep study).

This will depend on the severity of the sleep apnea. Simple ways to treat sleep apnea include nasal sprays, adhesive strips, weight loss, nerve stimulators, and sleep aid items. CPAP machines are sometimes used to manage sleep apnea. For severe cases, surgery procedures like somnoplasty, nasal surgery, and jaw surgery are options.
