Official coding guidelines
From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.
- Section I.C.16.d Prematurity and Fetal Growth Retardation (page 73), covers P05-P08
Code prematurity only when documented. Base P05 and P07 codes on recorded birth weight and estimated gestational age; when both are known, assign two P07 codes with birth weight sequenced before gestational age.

About the condition

Birth Weight
Birth weight is the first weight of your baby, taken just after being born. A low birth weight means that the baby is less than 5 pounds, 8 ounces. A high birth weight means that the baby is more than 8 pounds, 13 ounces.
