In a TOB code, which digit indicates the sequence of the bill within an episode of care?

• A. The first digit
• B. The second digit
• C. The third digit
• D. The fourth digit

Answer: (D)

The demand here is to identify how Type of Bill (TOB) codes show the order of billing within a single episode of care. A TOB is a four-digit code used on UB-04 claims, and while the first three digits describe the general billing category (what type of bill this is, such as inpatient vs outpatient and related classification), the fourth digit specifically marks the sequence of the bill within that episode. This last digit helps payers link multiple claims to the same hospitalization or care episode by indicating the bill’s position in the sequence (for example, whether it’s the first, second, or subsequent bill).
