CPT Code 90648 | Description & Clinical Information
CPT 90648 describes the administration of a vaccine that protects against Haemophilus influenza B, a bacteria that causes meningitis, by injecting it into a muscle as part of a four-dose schedule.
Official Description
The CPT book defines CPT code 90648 as: “Haemophilus influenzae type b vaccine (Hib), PRP-T conjugate, 4 dose schedule, for intramuscular use”.
Clinical Information
The procedure described by CPT code 90648 involves the administration of Haemophilus influenza B (Hib) PRPT conjugate vaccine into the patient’s muscle. This vaccine is given as part of a four-dose schedule to protect against Hib bacteria that can cause serious illnesses such as meningitis, pneumonia, and epiglottitis.
Before the vaccine is administered, the patient and their family are provided with counseling and instructions. This includes information about the benefits of the vaccine and the potential side effects. The provider also discusses precautions that need to be taken before and after the injection.
Appropriate patient preparation is crucial for the safe and effective administration of the vaccine. The provider may ask questions about the patient’s medical history, allergies, and current medications. They may also check the patient’s vital signs and assess their overall health.
During the injection, the provider will select an appropriate site on the patient’s body – such as the thigh or upper arm – and ensure that the area is clean and sterile. The needle is then inserted into the muscle and the vaccine is injected slowly. After the injection, the provider will observe the patient to ensure that they do not experience any adverse reactions.
It is important for patients to complete the full four-dose schedule to ensure maximum protection against Hib bacteria. The second and third doses are usually administered at one to two-month intervals, while the fourth dose is given at 12 to 15 months of age.
Although the Hib vaccine is generally safe and well-tolerated, some patients may experience side effects such as fever, irritability, and injection site pain. These symptoms are usually mild and go away on their own within a few days.
In summary, the administration of the Hib PRPT conjugate vaccine as described by CPT code 90648 is a routine procedure that is essential for protecting against serious illnesses caused by Hib bacteria. With proper patient preparation, counseling, and precautions, the vaccine can be administered safely and effectively as part of a four-dose schedule.
