Specific code 2014 ICD-9-CM Diagnosis Code 424.0
Mitral valve disorders
  • Billable Code
  • Short description: Mitral valve disorder.
  • ICD-9-CM 424.0 will be replaced by an equivalent ICD-10-CM code (or codes) when the United States transitions from ICD-9-CM to ICD-10-CM on October 1, 2015.
  • ICD-9-CM 424.0 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 424.0 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?
