The Centers for Medicare & Medicaid Services (CMS) issued Change Request (CR) 6698 to clarify how Medicare claim review contractors review claims and medical documentation submitted by providers. This clarification included an outline of new rules for signatures and added language for e-prescribing.
The previous language in the Program Integrity Manual (PIM) required a “legible identifier” in the form of a handwritten or electronic signature for every service provided or ordered. CR 6698 updates these requirements to require that every service provided or ordered be “authenticated by the author” by handwritten or electronic signature; stamp signatures are generally unacceptable.
CR 6698 also provides some exceptions to the signature requirement. First, facsimiles of original written or electronic signatures are acceptable for certifications of terminal illness for hospice. Second, there are other circumstances for which an order does not need to be signed. For example, orders for clinical diagnostic tests are not required to be signed, but there must be medical documentation by the treating physician that s/he intended the clinical diagnostic test to be performed. The documentation showing intent must be authenticated by the author with a handwritten or electronic signature. Finally, other regulations and CMS instructions regarding signatures take precedence. For example, if the NCD, LCD, and CMS manuals have specific signature requirements, those signature requirements take precedence. However, if these are silent as to signature requirements, the reviewer should follow the guidelines set forth in CR 6698.
