Valid for Submission
A49.1 is a billable diagnosis code used to specify a medical diagnosis of streptococcal infection, unspecified site. The code A49.1 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code A49.1 might also be used to specify conditions or terms like bacterial infection due to streptococcus milleri group, drug resistant streptococcus pneumoniae disease, infantile streptococcal infection, infantile streptococcal infection, infection caused by alpha-hemolytic streptococcus , infection caused by beta-hemolytic streptococcus, etc.
Unspecified diagnosis codes like A49.1 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Convert A49.1 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code A49.1 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Also called: Strep
Strep is short for Streptococcus, a type of bacteria. There are several types. Two of them cause most of the strep infections in people: group A and group B.
Group A strep causes
- Strep throat - a sore, red throat. Your tonsils may be swollen and have white spots on them.
- Scarlet fever - an illness that follows strep throat. It causes a red rash on the body.
- Impetigo - a skin infection
- Toxic shock syndrome
- Cellulitis and necrotizing fasciitis (flesh-eating disease)
Group B strep can cause blood infections, pneumonia and meningitis in newborns. A screening test during pregnancy can tell if you have it. If you do, I.V. antibiotics during labor can save your baby's life. Adults can also get group B strep infections, especially if they are elderly or already have health problems. Strep B can cause urinary tract infections, blood infections, skin infections and pneumonia in adults.
Antibiotics are used to treat strep infections.
