Preterm newborn, unspecified weeks of gestation

This code signifies a liveborn infant delivered before 37 completed weeks of gestation, where the specific gestational age at birth is not documented or is unknown. It indicates prematurity without further specification of the degree of prematurity.

Use this code when a newborn is identified as preterm, but the medical record lacks precise documentation of the gestational age at birth (e.g., "preterm infant," "premature baby"). Documentation supporting its use would include a physician's statement of prematurity without a specific week count.

• Only use this code when the exact gestational age is truly unspecified; otherwise, use a more specific P07.3- code.
• Always sequence this code as a principal diagnosis for the newborn when prematurity is the reason for admission.
• Do not use this code if the infant is full-term or post-term.
