Retired - Correct Coding - inFlow™ Intraurethral Valve-Pump (Vesiflo, Inc.)

DME MAC Joint Publication

The inFlow™ Intraurethral Valve-Pump is a urinary device for women with incomplete bladder emptying due to impaired detrusor contractility (IDC).  The inFlow™ is promoted as an alternative to urinary catheters.  The device consists of a small catheter with an internal, magnetically-activated pump-valve mechanism. The inFlow™ is placed in the female urethra for up to 30 days.  Upon activation by a battery-powered wand held low over the pubic area, the valve opens and the pump induces urine flow.

Effective 01/01/2016, the inFlow™ Intraurethral Valve-Pump was assigned HCPCS code A4335 (INCONTINENCE SUPPLY, MISCELLANEOUS). This HCPCS code must be used on claims for initial issue of inFlowTM, and is all-inclusive (catheter, wand, and batteries).  In addition, claims for replacement catheters, batteries, or wands must also use HCPCS code A4335.

Claims must include the manufacturer and product name in the narrative field of the electronic claim.
