Radial collateral ligament sprain of right elbow, init

This diagnosis code signifies a sprain, or stretching/tearing, of the radial collateral ligament (RCL) in the right elbow. The RCL is a key stabilizer on the outer (lateral) side of the elbow joint, connecting the humerus to the radius. Injury to this ligament typically results from a varus stress or hyperextension force.

This code is appropriate for documenting an initial encounter for a patient presenting with a newly diagnosed radial collateral ligament sprain of the right elbow. This includes the first time the patient is seen by a provider for this specific injury, regardless of whether treatment is initiated or further evaluation is planned. It is used when the injury is acute or subacute and the patient is receiving active treatment.

• Ensure documentation specifies the right elbow and confirms the injury is to the radial collateral ligament.
• Verify the encounter is truly the "initial encounter" for this specific injury; subsequent encounters will require a different seventh character.
• Distinguish from ulnar collateral ligament injuries or other elbow sprains, which have different codes.
