Wiki repeat testing/recurrent miscarriage

[Girlzsmom66]

I have a general question regarding sonohysterograms and hysterosalpingograms.

If a patient patient has had recurrent miscarriages and the doctor has trended her hcg levels down to zero with the recommendation that a repeat sono or hsg be repeated after the zero lab draw, would it be appropriate to use z31.41 again? (initially used as a diagnostic test)

Thanks fellow coders!
