Code Classification

  • Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified
    • General symptoms and signs
      • Shock, not elsewhere classified

R57.9 is a billable diagnosis code used to specify a medical diagnosis of shock, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like R57.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

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.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Acute kidney injury due to circulatory failure
  • Cardiorenal syndrome
  • Impending shock
  • Ischemia of kidney
  • Organ dysfunction syndrome
  • Refractory shock
  • Shock
  • Shock caused by snake venom

Clinical Classification

Clinical Information

  • Anaphylaxis

    an acute hypersensitivity reaction due to exposure to a previously encountered antigen. the reaction may include rapidly progressing urticaria, respiratory distress, vascular collapse, systemic shock, and death.
  • Cold Shock Proteins and Peptides

    cellular proteins and peptides that are induced in response to cold stress. they are found in a broad variety of prokaryotic and eukaryotic organisms.
  • Cold-Shock Response

    a sequence of responses that occur when an organism is exposed to excessive cold. in humans, a fall in skin temperature triggers gasping, hypertension, and hyperventilation.
  • Combat Disorders

    neurotic reactions to unusual, severe, or overwhelming military stress.
  • Convulsive Therapy

    convulsions induced in order to treat mental disorders. it is used primarily in the treatment of severe affective disorders and schizophrenia.
  • Electroconvulsive Therapy

    electrically induced convulsions primarily used in the treatment of severe affective disorders and schizophrenia.
  • Electroshock

    induction of a stress reaction in experimental subjects by means of an electrical shock; applies to either convulsive or non-convulsive states.
  • Extracorporeal Shockwave Therapy

    a nonsurgical treatment that uses either high-energy shock waves or low energy acoustic waves to treat various musculoskeletal conditions (e.g., plantar fasciitis; tennis elbow). a probe placed on the skin conducts the shock waves thereby delivering a mechanical force to the body’s tissues.
  • Heat-Shock Response

    a sequence of responses that occur when an organism is exposed to excessive heat. in humans, an increase in skin temperature triggers muscle relaxation, sweating, and vasodilation.
  • High-Energy Shock Waves

    high-amplitude compression waves, across which density, pressure, and particle velocity change drastically. the mechanical force from these shock waves can be used for mechanically disrupting tissues and deposits.
  • Insulin Coma

    severe hypoglycemia induced by a large dose of exogenous insulin resulting in a coma or profound state of unconsciousness from which the individual cannot be aroused.
  • Lithotripsy

    the destruction of a calculus of the kidney, ureter, bladder, or gallbladder by physical forces, including crushing with a lithotriptor through a catheter. focused percutaneous ultrasound and focused hydraulic shock waves may be used without surgery. lithotripsy does not include the dissolving of stones by acids or litholysis. lithotripsy by laser is lithotripsy, laser.
  • Lithotripsy, Laser

    fragmentation of calculi, notably urinary or biliary, by laser.
  • Osmotic Pressure

    the pressure required to prevent the passage of solvent through a semipermeable membrane that separates a pure solvent from a solution of the solvent and solute or that separates different concentrations of a solution. it is proportional to the osmolality of the solution.
  • Respiratory Distress Syndrome

    a syndrome characterized by progressive life-threatening respiratory insufficiency in the absence of known lung diseases, usually following a systemic insult such as surgery or major trauma.
  • Shock

    a pathological condition manifested by failure to perfuse or oxygenate vital organs.
  • Shock, Cardiogenic

    shock resulting from diminution of cardiac output in heart disease.
  • Shock, Hemorrhagic

    acute hemorrhage or excessive fluid loss resulting in hypovolemia.
  • Shock, Septic

    sepsis associated with hypotension or hypoperfusion despite adequate fluid resuscitation. perfusion abnormalities may include but are not limited to lactic acidosis; oliguria; or acute alteration in mental status.
  • Shock, Surgical

    a type of shock that occurs as a result of a surgical procedure.
  • Shock, Traumatic

    shock produced as a result of trauma.
  • Status Asthmaticus

    a sudden intense and continuous aggravation of a state of asthma, marked by dyspnea to the point of exhaustion and collapse and not responding to the usual therapeutic efforts.
  • Hypovolemia

    an abnormally low volume of blood circulating through the body. it may result in hypovolemic shock (see shock).
  • Cardiorenal Syndrome

    a disorder of the heart and kidneys in which dysfunction of one of the organs induces dysfunction of the other organ.

Patient Education


Shock happens when not enough blood and oxygen can get to your organs and tissues. It causes very low blood pressure and may be life-threatening. It often happens along with a serious injury.

There are several kinds of shock. Hypovolemic shock happens when you lose a lot of blood or fluids. Causes include internal or external bleeding, dehydration, burns, and severe vomiting and/or diarrhea. Septic shock is caused by infections in the bloodstream. A severe allergic reaction can cause anaphylactic shock. An insect bite or sting might cause it. Cardiogenic shock happens when the heart cannot pump blood effectively. This may happen after a heart attack. Neurogenic shock is caused by damage to the nervous system.

Symptoms of shock include:

  • Confusion or lack of alertness
  • Loss of consciousness
  • Sudden and ongoing rapid heartbeat
  • Sweating
  • Pale skin
  • A weak pulse
  • Rapid breathing
  • Decreased or no urine output
  • Cool hands and feet

Shock is a life-threatening medical emergency and it is important to get help right away. Treatment of shock depends on the cause.

[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.
