Contrast medium

Substance that is injected into the body, introduced via catheter, or swallowed to allow radiographic images of internal structures that would normally be difficult to see on x-ray films. Also called contrast material.

Contribution limit

Maximum yearly contribution legally permitted to a participant’s account in a defined benefit pension plan (DBPP). This may include employer and employee contributions and forfeitures that have been reallocated from other participants’ accounts. The contribution limit is set under Section 415 of the Internal Revenue Code.

Contributory elements

Parts of documentation that confirm the selection of procedure codes for evaluation and management (E/M) services but may not be of sufficient quantity to make a change in code selection. An exception is if counseling or coordination of care requires more than half the intraservice time for the encounter, then time is used to determine the code selection when billing.
