Clin Endocrinol Metab. (See also the WHO's practical guide to thermal protection of the newborn.) Hull D. PMID: 776461 [Indexed for MEDLINE] Valid for Submission. Etiology Impaired thermoregulation is a known complication of many of the diagnoses commonly seen among patients in a PM&R practice. This code description may also have Includes , Excludes , Notes, Guidelines, Examples and other information. Outlook (Prognosis) Many causes of hypothalamic dysfunction are treatable. Most of the time, missing hormones can be replaced. On the other hand, it might be merely secondary to the specific physical characteristics of the newborn. 1976 Mar;5(1):39-54. Temperature regulation and disturbance in the newborn infant Clin Endocrinol Metab. P81.9 is a billable diagnosis code used to specify a medical diagnosis of disturbance of temperature regulation of newborn, unspecified. 1976 Mar;5(1):39-54. doi: 10.1016/s0300-595x(76)80007-2. Pathogenesis of thermoregulatory disorders. The code P81.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of … Regulation of body temperature in warm-blooded animals, i.e., maintenance of thermomoeostasis irrespective of the temperature of the environment, is an achievement of evolutionary development. Pyrexia may be caused by: A high environmental temperature. A condition in which exaggerated or abnormal changes in body temperature occur spontaneously or in response to environmental or internal stimuli. As newborn infants can only sweat a little, they are unable to cool themselves and, therefore, easily become too hot. Some medicines may help with problems related to appetite regulation. It TEMPERATURE REGULATION AND DISTURBANCE 51 might be argued that this is a biological adaptation which enhances the chances of survival (Hey, 1969). 1. ICD-10-CM Code for Disturbance of temperature regulation of newborn, unspecified P81.9 ICD-10 code P81.9 for Disturbance of temperature regulation of newborn, unspecified is a medical classification as listed by WHO under the range - Certain conditions originating in the perinatal period . Temperature regulation and disturbance in the newborn infant. Pyrexia or fever (high body temperature) is defined as an abdominal skin temperature of 37 °C or more, or an axillary temperature of 37.5 °C or more. Code Classification: Certain conditions originating in the perinatal period (P00–P96) Diagnosis Code: P81.9 Short Description: Disturbance of temperature regulation of newborn, unsp Long Description: Disturbance of temperature regulation of newborn, unspecified The code P81.9 is VALID for claim submission. a core body temperature of 36°C-36.4°C, moderate hypothermia as 35.9°C-32°C and severe hypothermia as less than 32°C10. Medicines are usually not effective for changes in temperature or sleep regulation. Typically a wet newborn with a high surface area to volume ratio moves from a The World Health Organization (WHO) recommends the delivery room temperature be at least 25 to 28° C (77.0 to 82.4° F) and that neonates be dried immediately and placed in skin-to-skin contact with the mother and covered. The rapid decline in temperature is mainly due to physical characteristics of the newborn and environmental factors of the delivery area.
