2025 ICD-10-CM code P28.33

Primary mixed sleep apnea of newborn.

This code is specific to newborns.It should not be used for adults or older children experiencing sleep apnea.Ensure that appropriate documentation supports the diagnosis of primary mixed sleep apnea as opposed to other types of apnea or respiratory disorders.

Medical necessity for diagnosing and treating primary mixed sleep apnea in newborns is established by the presence of clinically significant apnea events that may lead to hypoxia (low blood oxygen) and potentially life-threatening complications.The severity and frequency of these events determine the need for further investigation and intervention.

The clinical responsibility for diagnosing and managing primary mixed sleep apnea in newborns typically rests with neonatologists or pediatricians. This may involve monitoring the infant's respiratory patterns, conducting polysomnography (sleep study) if necessary, and implementing appropriate interventions such as continuous positive airway pressure (CPAP) therapy or other respiratory support.

IMPORTANT:If applicable, consider also coding congenital malformations of the respiratory system (Q30-Q34).

In simple words: This code is for a newborn baby who has a type of sleep apnea called primary mixed sleep apnea. This means the baby stops breathing during sleep due to a combination of problems with their brain signaling and their airway. This condition happens in babies and is diagnosed shortly after birth.

This ICD-10-CM code classifies primary mixed sleep apnea in a newborn infant.Mixed sleep apnea is characterized by a combination of central and obstructive apnea events. It's a condition specific to the perinatal period, meaning it originates before birth or within the first 28 days of life.This code should only be used for newborn records and not maternal records.

Example 1: A full-term newborn is admitted to the neonatal intensive care unit (NICU) exhibiting episodes of apnea, bradycardia, and desaturation. Polysomnography reveals a pattern consistent with primary mixed sleep apnea. The neonatologist diagnoses P28.33., A preterm infant is monitored in the NICU due to prematurity-related respiratory issues. During routine monitoring, the infant demonstrates cyclical episodes of apnea with a mixture of central and obstructive breathing patterns. The diagnostic code P28.33 is assigned., A healthy newborn is seen at a well-baby checkup at one month of age.The parents report pauses in breathing during sleep. A subsequent sleep study shows mixed sleep apnea. The code P28.33 is assigned after the evaluation.

Complete medical history, including gestational age, birth weight, Apgar scores, and any perinatal complications.Detailed description of apnea events, including frequency, duration, and associated symptoms. Results of polysomnography (if performed) documenting the presence of both central and obstructive apnea. Treatment plan and response to interventions (e.g., CPAP, respiratory support).

** Accurate diagnosis requires detailed clinical evaluation and potentially polysomnography to differentiate primary mixed sleep apnea from other forms of apnea.Always refer to the latest version of the ICD-10-CM coding manual for the most up-to-date information and guidelines.
