Important points for module 22 Categories range from P00 to P96 Of the 100 available categories 59 have been allocated. There is one inclusion at the beginning of this chapter, and 5 exclusions. Disorders related to length of gestation and foetal growth - birth weight takes priority over gestational age.

Live birth Live birth is the complete expulsion or extraction from its mother of a product of conception, irrespective of the duration of pregnancy, which after such separation, breaths or shows any other evidence of life, such as beating of the heart, pulsation of the umbilical cord, or definite movement of voluntary muscles, whether or not the umbilical cord has been cut or the placenta is attached; each product of such a birth is considered live born.

Foetal death Fetal death is death prior to the complete expulsion or extraction from its mother of a product of conception, irrespective of the duration of pregnancy, death is indicated by the fact that after such separation the foetus does not breath or shows any other evidence of life, such as beating of the heart, pulsation of the umbilical cord, or definite movement of voluntary muscles.

Birth weight The first weight of the fetus or new born obtained after birth

Low birth weight Birth weight less than 2500g (up to, and including 2499g)

Very low birth weight Birth weight less than 1500g (up to, and including 1499g)

Extremely low birth weight Birth weight less than 1000g (up to, and including 999g)

Neonatal period The neonatal period commences at birth & ends 28 completed days after birth

Neonatal death Deaths among live births during the first 28 completed days of life

Early neonatal death Deaths occurring during the first 7 days of life

Late neonatal death Deaths occurring after the 7 day but before 28 completed days of life

Important points for module 22 P07 gives guidance on the assignment of this code if both birth weight & gestational age are specified P10-P15 birth trauma is classified to six categories which are arranged according to the physical effect of the injury P35-P39 includes only congenital infections & parasitic disease & those infections acquired in utero or which are present at birth

A useful hint Exercise 14 has 5 codes!!
