16. Chapter 16: Certain Conditions Originating in the Perinatal Period (P00-P96) Flashcards
- a. General Perinatal Rules
1) Use of Chapter 16 Codes - Chapter 16: Certain Conditions Originating in the Perinatal Period (P00-P96)
1) Use of Chapter 16 Codes
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.
- a. General Perinatal Rules
2) Principal Diagnosis for Birth Record - Chapter 16: Certain Conditions Originating in the Perinatal Period (P00-P96)
2) Principal Diagnosis for Birth Record
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.

4) Use of Chapter 16 Codes after the Perinatal Period - Chapter 16: Certain Conditions Originating in the Perinatal Period (P00-P96)
4) Use of Chapter 16 Codes after the Perinatal Period
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.
- a. General Perinatal Rules
6) Code all clinically significant conditions - Chapter 16: Certain Conditions Originating in the Perinatal Period (P00-P96)
6) Code all clinically significant conditions
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.
- b. Observation and Evaluation of Newborns for Suspected Conditions not Found
- Chapter 16: Certain Conditions Originating in the Perinatal Period (P00-P96)
1) Assign a code from category Z05, Observation and evaluation of newborns and infants for suspected conditions ruled out, to identify those instances when a healthy newborn is evaluated for a suspected condition that is determined after study not to be present. Do not use a code from category Z05 when the patient has identified signs or symptoms of a suspected problem; in such cases code the sign or symptom.
2) 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.
3) Z05 on a birth record
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.
- d. Prematurity and Fetal Growth Retardation
16. Chapter 16: Certain Conditions Originating in the Perinatal Period (P00-P96)
d. Prematurity and Fetal Growth Retardation
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. Codes from category P05 should not be assigned with codes from category P07.
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.
- e. Low birth weight and immaturity status
16. Chapter 16: Certain Conditions Originating in the Perinatal Period (P00-P96)
e. Low birth weight and immaturity status
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.
- f. Bacterial Sepsis of Newborn
16. Chapter 16: Certain Conditions Originating in the Perinatal Period (P00-P96)
f. Bacterial Sepsis of Newborn
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.
- g. Stillbirth
16. Chapter 16: Certain Conditions Originating in the Perinatal Period (P00-P96)
g. Stillbirth
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.
