Live Action says the video, released Tuesday, demonstrates that an employee was willing to help a person sexually exploit minors.
Planned Parenthood of New York City said the conversation portrayed in the video was not accurate and was reported to management.
The video was the latest released by Live Action in recent days. Others have shown a man visiting Planned Parenthood clinics in Virginia and New Jersey, essentially under the same guise.
Planned Parenthood Federation of America said Monday it was retraining its employees who deal with patients on how to report potential risks to minors.
