Short Description:Staphylococcal infection, unspecified site
Long Description:Staphylococcal infection, unspecified site

Not Valid for Submission

ICD-10 A49.0 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of staphylococcal infection, unspecified site. The code is NOT valid for the year 2019 for the submission of HIPAA-covered transactions.

Consider the following ICD-10 codes with a higher level of specificity:

  • A49.01 - Methicillin susceptible Staphylococcus aureus infection, unspecified site
  • A49.02 - Methicillin resistant Staphylococcus aureus infection, unspecified site

Code Classification

  • Certain infectious and parasitic diseases (A00–B99)
    • Other bacterial diseases (A30-A49)
      • Bacterial infection of unspecified site (A49)

Information for Patients


Staphylococcal Infections

Also called: Staph

Staph is short for Staphylococcus, a type of bacteria. There are over 30 types, but Staphylococcus aureus causes most staph infections (pronounced "staff infections"), including

  • Skin infections
  • Pneumonia
  • Food poisoning
  • Toxic shock syndrome
  • Blood poisoning (bacteremia)

Skin infections are the most common. They can look like pimples or boils. They may be red, swollen and painful, and sometimes have pus or other drainage. They can turn into impetigo, which turns into a crust on the skin, or cellulitis, a swollen, red area of skin that feels hot.

Anyone can get a staph skin infection. You are more likely to get one if you have a cut or scratch, or have contact with a person or surface that has staph bacteria. The best way to prevent staph is to keep hands and wounds clean. Most staph skin infections are easily treated with antibiotics or by draining the infection. Some staph bacteria such as MRSA (methicillin-resistant Staphylococcus aureus) are resistant to certain antibiotics, making infections harder to treat.

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
