UB04 Type of Bill Code 0121: Hospital Inpatient (Medicare Part B only) - Admit through Discharge Claim

Introduction

Type of Bill Code 0121 represents a Hospital Inpatient (Medicare Part B only) - Admit through Discharge Claim. This code is reported in Field 4: Type of Bill.

Usage

This code is utilized when a patient is an inpatient in a hospital setting but is either not entitled to Medicare Part A benefits or has exhausted their Part A coverage. It signifies a claim for ancillary services covered under Medicare Part B for the entire duration of the stay, from admission through discharge.

Billing Impact

Using this code ensures that the facility is reimbursed for specific Part B services rather than the standard Part A DRG payment, preventing claim denials for exhausted benefits.
