Code Classification

  • Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified
    • Symptoms and signs involving the circulatory and respiratory systems
      • Other symptoms and signs involving the circulatory and respiratory system

R09.01 is a billable diagnosis code used to specify a medical diagnosis of asphyxia. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.

  • Anoxic encephalopathy
  • Anoxic encephalopathy due to asphyxiation
  • Asphyxiation
  • Collapse
  • Collapse due to asphyxia
  • Inhalation of liquid in lower respiratory tract

Clinical Classification

Clinical Information

  • Asphyxia

    a pathological condition caused by lack of oxygen, manifested in impending or actual cessation of life.
  • Asphyxia Neonatorum

    respiratory failure in the newborn. (dorland, 27th ed)
  • Short Rib-Polydactyly Syndrome

    a syndrome inherited as an autosomal recessive trait and incompatible with life. the main features are narrow thorax, short ribs, scapular and pelvic dysplasia, and polydactyly.
  • Asphyxia

    a state of general hypoxia and hypercapnea, resulting in acidosis, which affects all tissues in the body.
  • Carbon Dioxide and Exsanguination Euthanasia|Asphyxia Exsanguination|CARBON DIOXIDE EXSANGUINATION

    a method of euthanasia whereby a subject inhales carbon dioxide until asphyxiation occurs and then the body is immediately drained of blood.
  • Jeune Syndrome|Asphyxiating Thoracic Dystrophy

    a rare autosomal recessive inherited syndrome characterized by a narrow thorax, micromelia, and respiratory disturbances which may lead to asphyxiation. it may be associated with bilateral microcystic renal disease which may lead to renal failure.
  • Perinatal Depression|Birth Asphyxia|Birth Asphyxia|Birth Depression|Fetal Asphyxia|Intrapartum Asphyxia|Perinatal Asphyxia|Perinatal Asphyxia

    a condition characterized by cardiorespiratory and neurological depression following birth.
  • Suffocation|Asphyxiation

    the stopping of respiration or the asphyxia that results from it.
  • Collapse

    failure of a physiologic function or system.
  • Collapse of Device|Collapse

    problem associated with the buckling or crushing of material from external forces.
  • Collapsed Lumen|COLLAPSED LUMEN

    a finding in which the walls of a tube or tubular organ have contorted or buckled into its cavity or channel.
  • Collapsed Lung

    atelectasis of an entire lung.
  • Device Collapser

    a component designed to fold or collapse something.
  • Difficult to Fold or Unfold|Difficult to Fold, Unfold or Collapse

    problem associated with the use of the device in terms of the user experiencing difficulty to close or to spread out/extend length of the device, even if the operation is being performed according to labeled instructions for use.
  • Inferior Vena Cava Collapse Due to Sniff Test Indicator|IVCCSIND|Inferior Vena Cava Collapse Indicator|Inferior Vena Cava Collapse Sniff Ind|Inferior Vena Cava Collapse Sniff Ind

    an indication as to whether resting inferior vena cava diameter is reduced with sniff, which is defined as a sharp inhalation.
  • Shock|Circulatory Collapse

    a life-threatening condition that requires immediate medical intervention. it is characterized by reduced blood flow that may result in damage of multiple organs. types of shock include cardiogenic, hemorrhagic, septic, anaphylactic, and traumatic shock.

Patient Education

Breathing Problems

When you're short of breath, it's hard or uncomfortable for you to take in the oxygen your body needs. You may feel as if you're not getting enough air. Sometimes you can have mild breathing problems because of a stuffy nose or intense exercise. But shortness of breath can also be a sign of a serious disease.

Many conditions can make you feel short of breath:

  • Lung conditions such as asthma, emphysema, or pneumonia
  • Problems with your trachea or bronchi, which are part of your airway system
  • Heart disease can make you feel breathless if your heart cannot pump enough blood to supply oxygen to your body
  • Anxiety and panic attacks
  • Allergies

If you often have trouble breathing, it is important to find out the cause.

Food or small objects can cause choking if they get caught in your throat and block your airway. This keeps oxygen from getting to your lungs and brain. If your brain goes without oxygen for more than four minutes, you could have brain damage or die.

Young children are at an especially high risk of choking. They can choke on foods like hot dogs, nuts and grapes, and on small objects like toy pieces and coins. Keep hazards out of their reach and supervise them when they eat.

When someone is choking, quick action can be lifesaving. Learn how to do back blows, the Heimlich maneuver (abdominal thrusts), and CPR.

People drown when they get too much water in their lungs. You can drown in as little as an inch or two of water. Babies can drown in a sink or bathtub. Preschoolers are most likely to drown in a swimming pool. People who have seizure disorders are also at risk in the water. Drowning can happen quickly and silently.

Drowning precautions should include:

  • Fences around pools
  • Supervising children near any body of water, including tubs
  • Not swimming or boating when under the influence of alcohol or sedatives
  • Wearing life jackets when boating
  • Learning CPR

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
