P05
Disorders of newborn related to slow fetal growth and fetal malnutrition
P05 is a non-billable ICD-10-CM code category for disorders of newborn related to slow fetal growth and fetal malnutrition. Report a more specific code from it instead. It is part of the FY2027 code set, effective October 1, 2026. The more specific codes under it are P05.0 Newborn light for gestational age; P05.1 Newborn small for gestational age; P05.2 Newborn affected by fetal (intrauterine) malnutrition not light or small for gestational age and P05.9 Newborn affected by slow intrauterine growth, unspecified. Its coding notes include 5 Excludes2 entries.
Guidelines tips
From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.
Chapter 16 codes are never used on the maternal record, and chapter 15 codes are never used on the newborn record. Chapter 16 codes can be used for life if the condition persists.
Prematurity is coded only when documented. When birth weight and gestational age are both available, two P07 codes are assigned, weight first. P07 can also apply to an older child or adult whose health is still affected.
Excludes2
Not included here. Both codes may be reported if the patient has both conditions.
