R58 is a billable ICD-10-CM diagnosis code for hemorrhage, not elsewhere classified. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 314 through 316. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Circulatory signs and symptoms.

Clinical InformationClinical

  • Postoperative Hemorrhage

    hemorrhage following any surgical procedure. it may be immediate or delayed and is not restricted to the surgical wound.

  • Ecchymosis

    extravasation of blood into the skin, resulting in a nonelevated, rounded or irregular, blue or purplish patch, larger than a petechia.

  • Exsanguination

    rapid and extreme blood loss leading to hemorrhagic shock.

  • Ascorbic Acid Deficiency

    a condition due to a dietary deficiency of ascorbic acid (vitamin c), characterized by malaise, lethargy, and weakness. as the disease progresses, joints, muscles, and subcutaneous tissues may become the sites of hemorrhage. ascorbic acid deficiency frequently develops into scurvy in young children fed unsupplemented cow's milk exclusively during their first year. it develops also commonly in chronic alcoholism. (cecil textbook of medicine, 19th ed, p1177)

  • Scurvy

    an acquired blood vessel disorder caused by severe deficiency of vitamin c (ascorbic acid) in the diet leading to defective collagen formation in small blood vessels. scurvy is characterized by bleeding in any tissue, weakness, anemia, spongy gums, and a brawny induration of the muscles of the calves and legs.

  • Traumatic Hemorrhage

    vascular rupture, and the resulting loss of blood, due to physical injury.

  • Easy Bruising

    appearance of skin bruises following perceived minimal contact or injury.

  • Anesthesia and Exsanguination Euthanasia|ANESTHETIZED EXSANGUINATION

    a method of euthanization whereby a subject is anesthetized and the body is drained of blood.

  • Anesthetized Exsanguination and Perfusion Euthanasia|ANESTHETIZED EXSANGUINATION AND PERFUSION|Anesthetized Perfusion

    a method of euthanasia whereby a subject is anesthetized and the blood of the body is replaced by a perfusate.

  • Anesthetized Intracardiac Lethal Injection and Exsanguination Euthanasia|ANESTHETIZED LETHAL INJECTION INTRACARDIAC EXSANGUINATION

    a method of euthanasia whereby a subject is anesthetized, a lethal chemical is administered by intracardiac injection and the body is drained of blood.

  • Anesthetized Intraperitoneal Lethal Injection and Exsanguination Euthanasia|ANESTHETIZED LETHAL INJECTION INTRAPERITONEAL EXSANGUINATION

    a method of euthanasia whereby a subject is anesthetized, a lethal chemical is administered by intraperitoneal injection and the body is drained of blood.

  • Anesthetized Lethal Injection Exsanguination Euthanasia|ANESTHETIZED LETHAL INJECTION EXSANGUINATION

    a method of euthanasia whereby a subject is anesthetized, a lethal chemical is administered by injection and the body is drained of blood.

  • Anesthetized Lethal Injection Intravenous Exsanguination Euthanasia|ANESTHETIZED LETHAL INJECTION INTRAVENOUS EXSANGUINATION

    a method of euthanasia whereby a subject is anesthetized, a lethal chemical is administered by intravenous injection and the body is drained of blood.

  • Captive Bolt and Exsanguination Euthanasia|CAPTIVE BOLT EXSANGUINATION

    a method of euthanasia whereby a subject is shot in the brain with a captive bolt pistol causing immediate and permanent unconsciousness or death, followed by draining the body of blood.

  • 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.

  • Exsanguination

    extensive loss of blood due to internal or external hemorrhage.

  • Intracardiac Lethal Injection and Exsanguination Euthanasia|LETHAL INJECTION INTRACARDIAC EXSANGUINATION

    a method of euthanasia whereby a subject is given a lethal intracardiac injection and the body is drained of blood.

  • Intraperitoneal Lethal Injection and Exsanguination Euthanasia|LETHAL INJECTION INTRAPERITONEAL EXSANGUINATION

    a method of euthanasia whereby a subject is given a lethal intraperitoneal injection and the body is drained of blood.

  • Intravenous Lethal Injection and Exsanguination Euthanasia|LETHAL INJECTION INTRAVENOUS EXSANGUINATION

    a method of euthanasia whereby a subject is given a lethal intravenous injection and the body is drained of blood.

  • Lethal Injection and Exsanguination Euthanasia|LETHAL INJECTION EXSANGUINATION

    a method of euthanasia whereby a subject is given a lethal injection and the body is drained of blood.

Patient EducationClinical

Bleeding

Bleeding is the loss of blood. It can be external, or outside the body, like when you get a cut or wound. It can also be internal, or inside the body, like when you have an injury to an internal organ. Some bleeding, such as gastrointestinal bleeding, coughing up blood, or vaginal bleeding, can be a symptom of a disease.

Questions About R58Overview

Is R58 (Hemorrhage, not elsewhere classified) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report hemorrhage, not elsewhere classified on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does R58 group to?

When hemorrhage, not elsewhere classified is the principal diagnosis on an inpatient stay, it groups to MS-DRG 314, 315, 316, with relative weights from 0.6821 to 2.0852 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R58 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the hemorrhage, not elsewhere classified is established, that condition takes the principal position instead.

What is the ICD-9 equivalent of R58?

Under the General Equivalence Mappings, hemorrhage, not elsewhere classified converts to ICD-9-CM 459.0 (hemorrhage NOS). The mapping is a direct match.

Footnotes

[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.
