urethral dilation

Same question --

Doctor did a urethral dilation on a FEMALE patient. Because he used the MALE dilator, he insists we bill as 53605 --

I say, we chose the gender based on the patient, not the equipment used.

Also the "subsequent code"; i.e., 53621 is that used for same day or next day?

Thank you in advance for your help.

re: urethral dilation

53605 is a gender specific code;
53605 M 2007-01-01 9999-01-01
It is not based on equipment!
"Subsequent" depends on the planned therapy.

The initial and subsequent dilation codes are used for each separate individual course of treatment. Once a patient has had an initial dilation, it does not follow that from the time on all dilations performed should be coded as subsequent dilations. A patient may undergo a urethral dilation with a proposed plan to dilate the stricture to 24F. The initial dilation code is used for the first dilation of the planned therapy, and the subsequent dilation code is used for all dilations after this initial dilation until the planned dilation size is 24F is reached. If the patient subsequently returns 3 months later and undergoes urethral dilations for another planned dilation to 24F, the initial code is 53600, is billed again first followed by subsequent dilation (code 53601) billings until the 24F dilation is reached.
