Oxygen Therapy

What is oxygen?

Oxygen is a gas that your body needs to work properly. Your cells need oxygen to make energy. Your lungs absorb oxygen from the air you breathe. The oxygen enters your blood from your lungs and travels to your organs and body tissues.

Certain medical conditions can cause your blood oxygen levels to be too low. Low blood oxygen may make you feel short of breath, tired, or confused. It can also damage your body. Oxygen therapy can help you get more oxygen.

What is oxygen therapy?

Oxygen therapy is a treatment that provides you with extra oxygen to breathe in. It is also called supplemental oxygen. It is only available through a prescription from your health care provider. You may get it in the hospital, another medical setting, or at home. Some people only need it for a short period of time. Others will need long-term oxygen therapy.

There are different types of devices that can give you oxygen. Some use tanks of liquid or gas oxygen. Others use an oxygen concentrator, which pulls oxygen out of the air. You will get the oxygen through a nose tube (cannula), a mask, or a tent. The extra oxygen is breathed in along with normal air.

There are portable versions of the tanks and oxygen concentrators. They can make it easier for you to move around while using your therapy.

Who needs oxygen therapy?

You may need oxygen therapy if you have a condition that causes low blood oxygen, such as:

  • COPD (chronic obstructive pulmonary disease)
  • Pneumonia
  • COVID-19
  • A severe asthma attack
  • Late-stage heart failure
  • Cystic fibrosis
  • Sleep apnea

What are the risks of using oxygen therapy?

Oxygen therapy is generally safe, but it can cause side effects. They include a dry or bloody nose, tiredness, and morning headaches.

Oxygen poses a fire risk, so you should never smoke or use flammable materials when using oxygen. If you use oxygen tanks, make sure your tank is secured and stays upright. If it falls and cracks or the top breaks off, the tank can fly like a missile.

What is hyperbaric oxygen therapy?

Hyperbaric oxygen therapy (HBOT) is a different type of oxygen therapy. It involves breathing oxygen in a pressurized chamber or tube. This allows your lungs to gather up to three times more oxygen than you would get by breathing oxygen at normal air pressure. The extra oxygen moves through your blood and to your organs and body tissues. HBOT is used to treat certain serious wounds, burns, injuries, and infections. It also treats air or gas embolisms (bubbles of air in your bloodstream), decompression sickness suffered by divers, and carbon monoxide poisoning.

But some treatment centers claim that HBOT can treat almost anything, including HIV/AIDS, Alzheimer's disease, autism, and cancer. The U.S. Food and Drug Administration (FDA) has not cleared or approved the use of HBOT for these conditions. There are risks to using HBOT, so always check with your primary health care provider before you try it.

ICD-9 Footnotes

General Equivalence Map Definitions
The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.

Index of Diseases and Injuries Definitions

  • And - The word "and" should be interpreted to mean either "and" or "or" when it appears in a title.
  • Code also note - A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
  • Code first - Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
  • Type 1 Excludes Notes - A type 1 Excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • Type 2 Excludes Notes - A type 2 Excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • Includes Notes - This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
  • Inclusion terms - List of terms is included under some codes. These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • NEC "Not elsewhere classifiable" - This abbreviation in the Alphabetic Index represents "other specified". When a specific code is not available for a condition, the Alphabetic Index directs the coder to the "other specified” code in the Tabular List.
  • NOS "Not otherwise specified" - This abbreviation is the equivalent of unspecified.
  • See - The "see" instruction following a main term in the Alphabetic Index indicates that another term should be referenced. It is necessary to go to the main term referenced with the "see" note to locate the correct code.
  • See Also - A "see also" instruction following a main term in the Alphabetic Index instructs that there is another main term that may also be referenced that may provide additional Alphabetic Index entries that may be useful. It is not necessary to follow the "see also" note when the original main term provides the necessary code.
  • 7th Characters - Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
  • With - The word "with" should be interpreted to mean "associated with" or "due to" when it appears in a code title, the Alphabetic Index, or an instructional note in the Tabular List. The word "with" in the Alphabetic Index is sequenced immediately following the main term, not in alphabetical order.
