Specific code 2009 ICD-9-CM Diagnosis Code 412
Old myocardial infarction
  • Short description: OLD MYOCARDIAL INFARCT.
  • ICD-9-CM 412 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 412 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).

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 412 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?
