Disorders of newborn related to short gestation and low birth weight, not elsewhere classified

Instructional notes

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 P07

  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.

Other Chapter 16 topics:

• General Perinatal Rules (page 71)
• Observation and Evaluation of Newborns for Suspected Conditions not Found (page 73)
• Coding Additional Perinatal Diagnoses (page 73)
• Low birth weight and immaturity status (page 74)
• Bacterial Sepsis of Newborn (page 74)
• Stillbirth (page 74)
• COVID-19 Infection in Newborn (page 74)

P07 MS-DRGs

As the principal diagnosis, the billable codes under P07 group to MS-DRG 791, 792, or 790 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.

• DRG 791 Prematurity with Major Problems (16 of 27 codes)
• DRG 792 Prematurity without Major Problems (16 of 27 codes)
• DRG 790 Extreme Immaturity or Respiratory Distress Syndrome, Neonate (11 of 27 codes)
