ICD-10-CM Official Guidelines for Coding and Reporting, quoted in full. Published by CMS and NCHS; in the public domain.

I.C.16 Chapter 16: Certain Conditions Originating in the Perinatal Period names this code p.71

(P00-P96) For coding and reporting purposes the perinatal period is defined as before birth through the 28th day following birth. The following guidelines are provided for reporting purposes.

I.C.16.a.1 Use of Chapter 16 Codes chapter guidance p.71

Codes in this chapter are never for use on the maternal record. Codes from Chapter 15, the obstetric chapter, are never permitted on the newborn record. Chapter 16 codes may be used throughout the life of the patient if the condition is still present.

I.C.16.a.2 Principal Diagnosis for Birth Record chapter guidance p.71

When coding the birth episode in a newborn record, assign a code from category Z38, Liveborn infants according to place of birth and type of delivery, as the principal diagnosis. A code from category Z38 is assigned only once, to a newborn at the time of birth. If a newborn is transferred to another institution, a code from category Z38 should not be used at the receiving hospital. A code from category Z38 is used only on the newborn record, not on the mother’s record.

I.C.16.a.3 Use of Codes from other Chapters with Codes from Chapter 16 chapter guidance p.72

Codes from other chapters may be used with codes from chapter 16 if the codes from the other chapters provide more specific detail. Codes for signs and symptoms may be assigned when a definitive diagnosis has not been established. If the reason for the encounter is a perinatal condition, the code from chapter 16 should be sequenced first.

I.C.16.a.4 Use of Chapter 16 Codes after the Perinatal Period chapter guidance p.72

Should a condition originate in the perinatal period, and continue throughout the life of the patient, the perinatal code should continue to be used regardless of the patient’s age.

I.C.16.a.5 Birth process or community acquired conditions chapter guidance p.72

If a newborn has a condition that may be either due to the birth process or community acquired and the documentation does not indicate which it is, the default is due to the birth process and the code from Chapter 16 should be used. If the condition is community-acquired, a code from Chapter 16 should not be assigned. For COVID-19 infection in a newborn, see guideline I.C.16.h.

I.C.16.a.6 Code all clinically significant conditions chapter guidance p.72

All clinically significant conditions noted on routine newborn examination should be coded. A condition is clinically significant if it requires:  clinical evaluation; or  therapeutic treatment; or  diagnostic procedures; or  extended length of hospital stay; or  increased nursing care and/or monitoring; or  has implications for future health care needs Note: The perinatal guidelines listed above are the same as the general coding guidelines for “additional diagnoses,” except for the final point regarding implications for future health care needs. Codes should be assigned for conditions that have been specified by the provider as having implications for future health care needs.

I.C.16.b Observation and Evaluation of Newborns for Suspected chapter guidance p.73

Conditions not Found

I.C.16.b.1 Use of Z05 codes chapter guidance p.73

Assign a code from category Z05, Observation and evaluation of newborn for suspected diseases and conditions ruled out, to identify those instances when a healthy newborn is evaluated for a suspected condition/disease that is determined after study not to be present. Do not use a code from category Z05 when the patient is documented to have signs or symptoms of a suspected problem; in such cases code the sign or symptom.

I.C.16.b.2 Z05 on other than the birth record chapter guidance p.73

A code from category Z05 may also be assigned as a principal or first- listed code for readmissions or encounters when the code from category Z38 code no longer applies. Codes from category Z05 are for use only for healthy newborns and infants for which no condition after study is found to be present.

I.C.16.b.3 Z05 on a birth record chapter guidance p.73

A code from category Z05 is to be used as a secondary code after the code from category Z38, Liveborn infants according to place of birth and type of delivery.

I.C.16.c.1 Assigning codes for conditions that require treatment chapter guidance p.73

Assign codes for conditions that require treatment or further investigation, prolong the length of stay, or require resource utilization.

I.C.16.c.2 Codes for conditions specified as having implications for future chapter guidance p.73

health care needs Assign codes for conditions that have been specified by the provider as having implications for future health care needs. Note: This guideline should not be used for adult patients.

I.C.16.d Prematurity and Fetal Growth Retardation chapter guidance p.73

Providers utilize different criteria in determining prematurity. A code for prematurity should not be assigned unless it is documented. Assignment of codes in categories P05, Disorders of newborn related to slow fetal growth and fetal malnutrition, and P07, Disorders of newborn related to short gestation and low birth weight, not elsewhere classified, should be based on the recorded birth weight and estimated gestational age. When both birth weight and gestational age are available, two codes from category P07 should be assigned, with the code for birth weight sequenced before the code for gestational age.

I.C.16.e Low birth weight and immaturity status chapter guidance p.74

Codes from category P07, Disorders of newborn related to short gestation and low birth weight, not elsewhere classified, are for use for a child or adult who was premature or had a low birth weight as a newborn and this is affecting the patient’s current health status. See Section I.C.21. Factors influencing health status and contact with health services, Status.

I.C.16.f Bacterial Sepsis of Newborn chapter guidance p.74

Category P36, Bacterial sepsis of newborn, includes congenital sepsis. If a perinate is documented as having sepsis without documentation of congenital or community acquired, the default is congenital and a code from category P36 should be assigned. If the P36 code includes the causal organism, an additional code from category B95, Streptococcus, Staphylococcus, and Enterococcus as the cause of diseases classified elsewhere, or B96, Other bacterial agents as the cause of diseases classified elsewhere, should not be assigned. If the P36 code does not include the causal organism, assign an additional code from category B96. If applicable, use additional codes to identify severe sepsis (R65.2-) and any associated acute organ dysfunction.

I.C.16.g Stillbirth chapter guidance p.74

Code P95, Stillbirth, is only for use in institutions that maintain separate records for stillbirths. No other code should be used with P95. Code P95 should not be used on the mother’s record.

I.C.16.h COVID-19 Infection in Newborn chapter guidance p.74

For a newborn that tests positive for COVID-19, assign code U07.1, COVID-19, and the appropriate codes for associated manifestation(s) in neonates/newborns in the absence of documentation indicating a specific type of transmission. For a newborn that tests positive for COVID-19 and the provider documents the condition was contracted in utero or during the birth process, assign codes P35.8, Other congenital viral diseases, and U07.1, COVID-19. When coding the birth episode in a newborn record, the appropriate code from category Z38, Liveborn infants according to place of birth and type of delivery, should be assigned as the principal diagnosis.
