We're often asked about the correct ICD-10 CM diagnosis codes to submit on a claim for a general health exam provided to a newborn, infant, or child. Let's take a look at how to approach this type of coding.
Just like the same general health examination diagnosis codes used in ICD-9 CM, the ICD-10 CM diagnosis codes are also “age banded.” Each diagnosis code has a specific age range to differentiate between a newborn, an infant, and a child.
Use the list of diagnosis codes to select the correct ICD-10 CM diagnosis code: Z00.110 - Health exam for newborn, under 8 days old.
- Z00.111 - Health exam for newborn, 8-28 days old
- Z00.121 - Encounter for routine child health exam, child over 28 days old, with abnormal findings
- Z00.129 - Encounter for routine child health exam, child over 28 days old, without abnormal findings
For further details and explanation, refer to Chapter 21 “Factors Influencing Health Status and Contact with Health Services” in the “2017 Official Guidelines for Coding and Reporting” in the ICD-10 CM Code Book.
