What 52204 covers

A urologist passes a cystoscope through the urethra into the bladder, inspects the lining, and collects one or more tissue samples, commonly from a suspicious mucosal lesion. The samples are submitted for pathologic examination. The procedure may be performed in an office or a facility, depending on the patient and clinical circumstances.

Report 52204 for cystoscopic tissue sampling, rather than inspection alone or a session that treats a lesion by fulguration or resection. The operative note should identify the sampled site or sites and the reason for biopsy; report the procedure once, not by specimen count. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Endoscopy-family pricing applies when related endoscopies are performed together. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

52204 billing questions

When is 52204 appropriate instead of a treatment code?

Use 52204 when cystoscopy is used to obtain tissue for examination. When the session treats a lesion by fulguration or resection instead, select the code that describes that treatment.

Is 52204 reported once for each biopsy specimen?

No. Report the procedure once for the cystoscopic biopsy session, not once per specimen. Document the sampled site or sites and the clinical reason for sampling.

How does 52204 differ from diagnostic cystoscopy?

A diagnostic cystoscopy involves inspection without tissue sampling. Report 52204 when the cystoscopic procedure includes biopsy.

Can modifier 50 be used for biopsies from both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 is not used.

What happens when related endoscopies are performed in the same session?

CMS endoscopy-family pricing applies when related endoscopies are performed together. The same-day preoperative and postoperative care is included in the 0-day global period.

Can an assistant surgeon or co-surgeon be billed?

Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
