What 54240 covers
Penile plethysmography measures changes in penile circumference or volume while a patient is exposed to a controlled stimulus protocol. A trained clinician or staff member conducts the test, and a physician interprets the recorded response. It is used in specialized urology or sexual-medicine evaluations when the question concerns the physiologic response to stimuli, rather than sleep-related erections or anatomy alone.
Report 54240 when this measurement and interpretation are performed; documentation should identify the protocol, recorded response, clinical question, and interpretation. The global service includes same-day preoperative and postoperative care. The global service may be billed without a component modifier, or the interpretation with modifier 26 and the equipment and staff with modifier TC. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeon and team-surgery billing are not permitted.

How to choose
- 54250Nocturnal erection testingTumescence and rigidity
- Choose 54240 for stimulus-associated penile response measurement; choose 54250 for testing nocturnal tumescence and rigidity during sleep.
- 54230CavernosographyContrast injection
- 54230 is cavernosography, an imaging study of the corpora after injection. It does not measure the stimulus-response signal captured by 54240.
- 54231CavernosometryDynamic hemodynamic study
- 54231 assesses cavernosal hemodynamics with dynamic testing; 54240 records changes in penile circumference or volume during a stimulus protocol.
54240 billing questions
How is 54240 different from 54250?
54240 measures penile response during a controlled stimulus protocol. 54250 evaluates nocturnal penile tumescence and rigidity during sleep.
Can the professional and technical portions be billed separately?
Yes. Report modifier 26 for the physician's interpretation or modifier TC for the equipment and staff; without either modifier, the claim represents the global service.
What documentation supports 54240?
Document the clinical question, stimulus protocol, recorded penile response, and physician interpretation so the record shows that plethysmography was performed.
Should modifier 50 be used for bilateral testing?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What same-day care is included?
The 0-day global period includes same-day preoperative and postoperative care. Assistant-at-surgery payment requires documented medical necessity, while co-surgeon and team-surgery billing 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.
