Absolutely. Even solo practitioners can get tangled in payer requirements, especially with renewals and network changes. That's where physician credentialing services really help. They handle re-attestations, CAQH updates, and ensure you're linked correctly with every insurer. It's not about outsourcing because you can't; it's outsourcing because you shouldn't have to. Physicians should focus on care, not paperwork. Having professionals manage that side ensures nothing gets delayed or overlooked.
