Final answer:
The statement was edited to correct punctuation, ensuring clarity by separating independent clauses with a semicolon and following the transitional phrase with a comma.
Step-by-step explanation:
To correct the error in the statement, the punctuation must be revised for clarity. The edited sentence should be:
"Today, legislation controls organ-donation policies and procedures; indeed, organ and tissue donation is becoming one of the most regulated fields within health care."
This correction provides a semicolon to separate the two independent clauses and a comma to follow the transitional phrase 'indeed,' improving the readability and coherence of the statement.
