Practitioners listed here are registered with the relevant Duitsland medical authority and operate within national rules on scope of practice, prescribing rights, and continuing professional development. Care delivered in Cologne carries the additional benefits of local language support, in-person follow-up, and direct coordination with regional hospitals and labs.
