Preventive Visits and ICD 9 Diagnosis Codes

Gurgaon, Haryana
Best answers
Every preventive visit should be reported with an appropriate ICD-9-CM diagnosis code to reflect the reason for the visit. The most commonly used diagnosis codes associated with preventive services include:
• V70.0 Routine general medical examination at a health care facility for adults
• V70.3 should be used to identify examinations for administrative purposes, such as marriage and school admission
• V72.31 Routine gynecological examination for gynecologic exams
• V20.2 Routine infant or child health check for well-child care
• Additional special screening codes (V73.0-V82.9) may be used, as appropriate.

My question:

1) Can we bill any other ICD 9 diagnosis codes (beside the above listed V codes) along with preventive visit codes 99381–99429.
2) Do we need to bill these codes as primary diagnosis?
3) I've a claim scenario where the primary diagnosis is "042" - HIV , and the proc code is (99395) - preventive visit code. Will that be considered as preventive visit or its an upcoding scenario.
3) Can we consider annual wellness visit codes -G0438 and G0439 as preventive visit?

Please help me resolve these issues.

Many thanks for your valuable time in advance.
