Shock, not elsewhere classified (R57) ICD-10-CM

The R57 code range covers shock, not elsewhere classified with 5 ICD-10-CM diagnosis codes. 4 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

Type 1 Excludes

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.

Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the R57 range.

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.

Hypovolemia

An abnormally low volume of blood circulating through the body. It may result in hypovolemic shock (see SHOCK).

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.

About the R57 Code Range

The ICD-10 code R57 category is used to classify different types of shock that are not specified elsewhere in medical coding, covering various critical conditions where blood flow and oxygen delivery to tissues are dangerously reduced.

This section includes R57.0 for cardiogenic shock, which refers to heart-related causes such as cardiac arrest or cardiovascular collapse. It also covers R57.1, hypovolemic shock, often called hemorrhagic shock, resulting from severe blood or fluid loss. The R57.8 code is used for other types of shock including neurogenic, obstructive, hypoglycemic, and vasogenic shock, which affect different body systems. Finally, R57.9 identifies unspecified shock cases, useful when the exact nature of shock isn’t known, including conditions like refractory shock, prerenal renal failure, or shock from rare causes such as snake venom. This categorization helps medical coders accurately assign codes based on the condition’s origin and clinical characteristics, streamlining diagnosis and treatment documentation.

Questions About This Page

How many billable codes are in the R57 range?

Of the 5 codes in this range, 4 are billable and valid for claim submission from October 1, 2025 through September 30, 2026. Category header codes group them but cannot be reported on claims.

What does the R57 range classify?

The range classifies shock, not elsewhere classified. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
