Other disturbances of temperature regulation of newborn (P81)

ICD-10 code P81 covers disturbances in how newborns regulate their body temperature. This section includes specific conditions like environmental hyperthermia, other identified temperature regulation issues, and unspecified fever-related disorders in newborns.

The code P81.0 is used for cases of environmental hyperthermia in newborns, where overheating occurs due to external temperature factors, sometimes called "hyperthermia" or "environmentally-induced hyperthermia." Meanwhile, P81.8 applies to other specified temperature problems such as biphasic fever, neonatal dehydration, or brief fever episodes termed "transitory fever of newborn." If the exact cause or type of temperature disturbance isn’t identified, P81.9 is used for unspecified cases, including a wide range of fever descriptions like viral fever, sweating fever, and intermittent or continuous fever patterns common in newborns. Understanding these synonyms helps medical coders accurately select the appropriate ICD-10 code for newborns experiencing abnormal temperature regulation. This ensures precise documentation for conditions affecting newborn temperature responses, differentiating among causes like environmental heat, dehydration, or unknown fever origins.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Drug Fever

Drug-induced fever.

Hyperthermia

An abnormal elevation of body temperature, usually as a result of inability to regulate core body temperature due to non-pathologic factors.

Hyperthermia, Induced

Abnormally high temperature intentionally induced in living things regionally or whole body. It is most often induced by radiation (heat waves, infra-red), ultrasound, or drugs.

Malignant Hyperthermia

Rapid and excessive rise of temperature accompanied by muscular rigidity following general anesthesia.

Phlebovirus

A genus of the family BUNYAVIRIDAE comprising many viruses, most of which are transmitted by Phlebotomus flies and cause PHLEBOTOMUS FEVER. The type species is RIFT VALLEY FEVER VIRUS.

Severe Fever with Thrombocytopenia Syndrome

A tick-borne infection with SEVERE FEVER WITH THROMBOCYTOPENIA SYNDROME BUNYAVIRUS of the genus Phlebovirus. It is associated with fever, THROMBOCYTOPENIA; LEUKOCYTOPENIA, and multiorgan dysfunction. It is found in parts of Asia including China, Japan, Korea and Vietnam and can be transmitted from infected domestic animals and humans.
