Give a coding example of when you shouldn't use Z34.

Answer 1

ICD 10 codes from category Z35 are used for encounters for supervision of normal pregnancy.

for eg. Z34.01 normal pregnancy for 1STtrimester

Z34.02 is normal pregnancy 2nd trimester

Z34.03 is normal pregnancy for 3rd trimester

If mother has any condition related to complicating or complicated by pregnancy

for coding of pregnancy complications O is used.

For example

O30.011 Twin pregnancy monochorionic,monoamniotic,first trimester

O30.012 Twin pregnancy monochorionic,monoamniotic second trimester

O30.013 Twin pregnancy monochorionic,monoamniotic third trimester

Patient diagnosed with eclampsia(hypertension,convulsions and proteinuria during third trimester

O15.00 Eclampsia in pregnancy unspecified

O15.02 eclampsia in pregnancy second trimester

O15.03 eclampsia in pregnancy 3rd trimester

Mrs.X admitted with twin pregnancy fetus 2 breech presentation will be coded as O32.1XX2

Z34.0 should not be used for reimbursement purposes also.
