2025 ICD-10-CM code P81.8

Other specified disturbances of temperature regulation of the newborn.

Always refer to the official ICD-10-CM coding guidelines and the complete descriptions of codes within Chapter 16 to ensure accurate coding.This code is only applicable to newborns within 28 days of life.

Medical necessity for coding P81.8 is established by documented evidence of a significant thermoregulatory disturbance in a newborn within the first 28 days of life.The lack of a more specific diagnosis should be supported by clinical findings.

The clinical responsibility for coding P81.8 rests with the physician or qualified healthcare professional providing care to the newborn.Accurate documentation of the newborn's thermoregulatory issues is crucial for appropriate coding.

IMPORTANT:Consider other codes within the P80-P83 block if a more specific condition applies.Refer to the full ICD-10-CM manual for differential diagnosis.

In simple words: This code describes problems with a newborn's ability to keep their body temperature normal in the first 28 days of life. This could be due to their body not being fully developed, the environment, or other health issues.

This ICD-10-CM code classifies other specified disturbances of temperature regulation in a newborn.It encompasses conditions affecting the newborn's ability to maintain normal body temperature, excluding those specifically listed elsewhere in Chapter 16.These disturbances may stem from various factors including immature thermoregulation, environmental factors, or underlying medical conditions.The code should only be used for newborns within the first 28 days of life.

Example 1: A newborn presents with hypothermia (low body temperature) that is not attributable to specific causes listed in other P-codes., A newborn exhibits signs of hyperthermia (high body temperature) and requires intervention, but the underlying cause isn't explicitly defined by other codes in Chapter 16., A newborn shows temperature instability, fluctuating between hypothermia and hyperthermia, without clear etiology specified elsewhere in the chapter.

Detailed documentation is needed, specifying the newborn's temperature readings, any interventions used (e.g., warming or cooling measures), and the duration and severity of the thermoregulatory disturbance.The absence of more specific diagnoses should be clearly stated.

** Code P81.8 should only be used when no other more specific code in Chapter 16 applies to the newborn's condition.The code should not be used on the maternal record.Always ensure proper documentation supports the use of this code.
