s the claim filing indicator code "OF" (SBR09) limited to Medicare Part D claims? For 5010 would the appropriate claim filing indicator for Black lung be "WC"?
The code “OF" is defined as other federal programs including but not limited to Medicare Part D. The code “OF” cannot be used for a federal program if another code on the list more accurately describes the program.
The Black lung program is administered by the Office of Workers Compensation programs. For this reason the committee feels that “WC” indicating workers compensation is the best description for the program.
