由于美国医疗改革，多数保险公司已不要求病人由家庭医生转诊看专科 - - 这就是变化。因此，了解美国临床医学分科对你就诊是必要的。
首先，我们应该了解美国医生是怎样培养的。医学院毕业后教育评审委员会
Accreditation Council for Graduate Medical Education (ACGME). 的官方网站 http://www.acgme.org/adspublic/default.asp 的 List of programs by specialty 可提供详细内容。
大的分类如下：
过敏与免疫学，麻醉科，皮肤科，急诊医学，家庭医学，内科医学，神经外科，神经内科，妇产科，眼科，整形外科，耳鼻喉科，病理科，小儿科，物理医学与康复，整形外科，预防医学，精神病学，放射肿瘤学，放射学诊断，外科，胸外科，胸外科综合，泌尿外科。 - 对应英文：
(Allergy and immunology, anesthesiology, dermatology, emergency medicine, family medicine, internist medicine, neurological surgery, neurology,obstetrics and gynecology, ophthalmology, orthopedic surgery, otolaryngology,pathology,pediatrics,physical medicine and rehabilitation, plastic surgery, preventive medicine,psychiatry, radiation oncology, radiology diagnostic, surgery, thoracic surgery, thoracic surgery integrated, urology.)
（亚）专科分类比较细致， 但也清晰。 专科医师都有专科训练（ Fellowship ）在各大科类中进行。比如 疼痛科在麻醉科训练后专科训练， 所以疼痛科医生也是麻醉医生。美国各医院内疼痛病人会诊都要求麻醉疼痛科医生进行。在中国， 2007 年中国卫生部正式发文建立疼痛科。由于麻醉疼痛科医生很少， 所以很多人包括很多医生都把康复科（物理医学与康复）误认为疼痛科。
希望在美的各专科医师提供更多关键信息，为华人社区服务。
