20.4.1 Diagnostic Service Defined

20.4.1 - Diagnostic Services Defined (Rev. 82; Issued: 02-08-08; Effective: 01-01-08; Implementation: 03-10-08) 

A service is “diagnostic” if it is an examination or procedure to which the patient is subjected, or which is performed on materials derived from a hospital outpatient, to obtain information to aid in the assessment of a medical condition or the identification of a disease. Among these examinations and tests are diagnostic laboratory services such as hematology and chemistry, diagnostic x-rays, isotope studies, EKGs, pulmonary function studies, thyroid function tests, psychological tests, and other tests given to determine the nature and severity of an ailment or injury.

410.2 PREV defined   42 cfr 410.2   - defined only by examples list, not by theory.

Could CMS's list of PREV services be segregated into logical and insightful categories?  EG GLAUCOMA and BMM are really "management of disease".  GLAUCOMA is left out of UPSTF, and USPSTF handles BMM very differently.

Inbtriguing phrase "screening, and other preventive services"  (E.g. OCP's are not screening, baby aspirin is not screening)

Wich are TESTS and which are nOT
