Half my doctors office visits are costing me "office visit" cheap copays and half are going towards my deductible as expensive "outpatient services"

I’m going back and forth between BCBS and the hospital corporation (LCMC) that all my doctors are affiliated with. Since the beginning of July, I’ve seen 5 different doctors in an office (1 endo, 2 obgyn, 1 pcp, 1 neuro PA) and had 6 total visits. I’ve been billed correctly and paid the appropriate copay of $5-50 for 3 of these visits (endo, 1 obgyn, neuro PA). The other 3 have told me I have a copay when I get there, then I got a bill from the hospital later for $60-90 (2 visits with the other obgyn, pcp).

BCBS is telling me these visits were coded as “outpatient” and thus go towards my deductible. The first time it happened, I called BCBS and we talked to the hospital billing. They told me they would resubmit it as an office visit. BCBS assured me my next visit would only cost $25, just for me to having the same issue now two more times. We called the hospital billing again, now this person says the first person I spoke to was incorrect and never resubmitted a claim because it was coded correctly. They also removed that initial visit from my billing section of the patient portal, so I thought it was resolved. She says they can charge me as an outpatient because they’re within 20 miles of the hospital campus. But, some of the providers I saw in the SAME BUILDING a few weeks apart with the same physician group were covered by my copay. The hospital billing dept is supposed to call me back today with answers.

These are the CPT codes, minus the one they hid from me, which was as a new patient:

99204 (x3 visits) – new patient office visit or other outpatient visit – these were all covered by my insurance, I only paid the copay.

99213 (x1 visit) – established patient office or other outpatient visit, 20-29 minutes; 99214 (x1 visit) – established patient office or other outpatient visit, 30-39 minutes; – these were not covered by my insurance.

Now that I’ve looked at the CPT codes, it looks like BCBS is the one in the wrong? On my EOB statements for all of these visits it says “office visit(s)” but only the new patient ones were covered. Maybe they’re making an error with the established patient visits?

Does a CPT code exists that is solely for office visits and doesn’t fall under the outpatient category as well? It looks like the hospital coded everything correctly, but BCBS interpreted it wrong. I have also looked into the laws about “outpatient” charges, and these are not listed on my bills as “facility fees” or anything like that, it’s just the provider’s charges.
