Centesis may be defined as the act of puncturing a body cavity or space with a hollow needle and drawing out fluid. Each centesis procedure involves both a puncture action and a needle aspiration action. It is correct to have two relationship groups for centesis procedures.
One group has a Method (attribute) of Puncture - action (qualifier value) and a Procedure site - Direct (attribute) of the structure being punctured.
A second group has a Method (attribute) of Aspiration - action (qualifier value) and a Procedure site - Indirect (attribute) of the space being aspirated.
For example,
91602002 |Thoracentesis (procedure)| has:
Role group 1:
Method = Puncture - action
Procedure site - Direct (attribute) = Pleural membrane structure (body structure)
Using device = Needle, device
Role group 2:
Method = Aspiration - action
Procedure site - Indirect (attribute) = Pleural cavity structure (body structure)
Using device = Needle, device
