2008 ICD-9-CM Diagnosis Code 742.4

Other specified congenital anomalies of brain

Short description: BRAIN ANOMALY NEC.
ICD-9-CM 742.4 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 742.4 should only be used for claims with a date of service on or before September 30, 2015. For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10-CM code (or codes).
You are viewing the 2008 version of ICD-9-CM 742.4.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 742.4 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
