In simple words: This code is used when you visit a doctor or other healthcare provider to check on how your birth control patch is working and to discuss any concerns.

This code is used for encounters with a healthcare professional for the purpose of monitoring or checking the effectiveness and any potential side effects of a transdermal (skin) patch hormonal contraceptive device.

Example 1: A patient has been using a transdermal contraceptive patch for three months and visits her physician for a routine follow-up to discuss its effectiveness and any side effects., A patient experiences skin irritation at the patch application site and consults her dermatologist for advice on managing the local reaction while continuing contraception., A patient who recently started using the contraceptive patch presents with concerns about irregular bleeding and seeks medical advice from her gynecologist.

The medical record should document the reason for the encounter, such as routine surveillance, management of side effects, or concerns about efficacy. Details of the patient's experience with the contraceptive patch, including any adverse reactions or questions, should be noted.

** This code specifically refers to surveillance of the transdermal patch hormonal contraceptive device, not other forms of contraception. Please refer to other Z codes for surveillance of other methods (pills, injectable, IUD, ring, implant, etc.).
