Magnetic Resonance Cholangiopancreatography

Magnetic resonance cholangiopancreatography (MRCP) may be considered medically necessary for diagnostic evaluation of the pancreaticobiliary system when:

· there is a low likelihood of needing therapeutic intervention or tissue sampling with ERCP or PTC,

· ERCP has been technically unsuccessful, or

· ERCP is considered unsafe or very unlikely to be successful (e.g., pediatric patient, major medical comorbidities, or complex pancreaticobiliary anatomy such as post biliary-enteric bypass).
