Not paying for Lactation Specialist consult

According to my maternity benefits on Bonfit select, I get 4 consultations after delivery with a midwife (1 of these can be used with a lactation specialist). I went onto the SACLC website and found a registered LC.

After the consult I received an invoice with the correct ICD-10 code (Z39.1) LACT01 which clearly states I went to see the LC for these services.

But, the registered LC is also a registered Dietician and Bonitas fails to pay due to her also being a dietician (practice code on the invoice).

Now Bonitas wants a LC practice code but there is no practice code for a LC? I can clearly show them that she is registered with SACLC.

I also asked Bonitas to give me a list of LC which they will cover, but NO SUCH list is available? So which LC do they cover? none?

They will ALWAYS find a reason not to pay and wont even listen to me when I say that she is BOTH a dietitian and LC!!!! all bonitas does is give me the definition of the two... but you can CLEARLY see per invoice I did not use her services as dietician but for a lactation consult!
