  • Care Type (Second Digit): Indicating the nature of care provided, this digit helps differentiate between Inpatient and Outpatient care, among other categories.
  • Bill Sequence/Frequency (Third and Fourth Digits): These digits detail the billing sequence, encompassing aspects such as non-payment, interim claims, and late charges.

As the foundation of Type of Bill codes, these components work together to create a comprehensive identifier for each billed service.

Decoding the Four-Digit Alphanumeric Code

The intricate nature of the four-digit alphanumeric code underscores its importance. Each digit contributes crucial information that collectively paints a precise picture of the billed service. From the type of facility to the care provided and the billing frequency, healthcare professionals decode these digits to streamline the billing process and facilitate accurate payment processing.

The Role of Leading Zeros and CMS Ignorance

The leading zero in Type of Bill codes serves as a subtle yet crucial element.
