Medical necessity is established when the use of an antiseptic, such as chlorhexidine, is clinically indicated to reduce the risk of infection before a procedure involving skin puncture or mucosal contact. This is especially important in patients with compromised immune systems or those undergoing procedures at high risk for infection.

Application of the antiseptic to the patient's skin by a healthcare professional (nurse, medical assistant, physician, or surgeon) before a medical procedure to reduce the risk of infection.

IMPORTANT For alcohol or peroxide, per pint, see A4244; For alcohol wipes, per box, see A4245; For Betadine® or phisohex solution, per pint, see A4246; For Betadine® or iodine swabs or wipes per box, see A4247.

In simple words: This code is for a small amount (1 milliliter) of antiseptic solution containing chlorhexidine. Doctors and nurses use it to clean a patient's skin before doing things like taking blood sugar tests or giving injections.This helps prevent infections.

HCPCS code A4248 represents a 1 ml chlorhexidine-containing antiseptic solution used for skin antisepsis prior to procedures such as blood glucose monitoring, injections, catheter insertions, or minor wound cleansing.The antiseptic solution is applied to the skin to reduce bacterial load and minimize the risk of infection.The application process typically involves cleaning the area, applying the solution with a sterile applicator, and allowing it to air dry.Mild skin irritation or allergic reactions are potential, albeit rare, complications.

Example 1: A diabetic patient requires a blood glucose test.The nurse uses A4248 to clean the patient's fingertip before the blood draw., Before inserting a peripheral intravenous (IV) catheter, a medical assistant uses A4248 to disinfect the insertion site., A minor wound requires cleaning and dressing. A physician uses A4248 to cleanse the wound before applying an antiseptic dressing.

Documentation should include the reason for using the antiseptic (e.g., pre-procedure skin disinfection), the site of application, the amount used (1 ml), the date and time of application, and any observed adverse reactions.
