Guidelines: Factors influencing health status and contact with health services (Z00-Z99)
Note: Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00-Y99 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:(a) When a person who may or may not be sick encounters the health services for some specific purpose, such as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
(b) When some circumstance or problem is present which influences the person's health status but is not in itself a current illness or injury."

Please help i have read the guidelines in icd-10 about 10 time and i can not find the answer. Patient comes for an annual exam z00.00 or z01.419 and the provider orders sti test. In icd-9 we used v74.5 screening for sexually transmitted disease. In icd-10 i used z11.3 encounter screening for infection with a predominantly sexual mode of transmission. Bcbs denied claim stating it is not a medical diagnosis. We see a lot of patients for screening sti's with no signs or symptoms. Please help me with correct coding for this process.

It may be that the carrier does not cover screening for STI. In which case it is patient responsibility. Also you may consider adding the code for high risk sexual behavior if applicable.
