Detailed Breakdown: Mastering the UB Form Fields
While the UB92 has transitioned to the UB04, the fundamental principles of institutional billing remain consistent. This section provides a deep dive into the critical fields, ensuring you understand the nuances of completing a UB 92 form or its modern equivalent, the UB04. We’ll explore how each piece of information contributes to a clean claim.
Understanding the UB-04: The Evolution from UB92
The UB-92 served as the standard institutional claim form from 1992 until 2007 when it was replaced by the UB04. The transition was driven by the need to accommodate new coding systems (like ICD-10-CM/PCS), NPI requirements, and other evolving healthcare regulations. While the UB04 introduced additional fields and updated some existing ones, the core structure and purpose of reporting institutional services remained largely the same. Many of the principles discussed here apply directly to the UB04, making this guide relevant for current billing practices. You can often find a printable UB 92 claim form or a UB 92 claim form pdf online for historical reference, but for current submissions, the UB04 is the required format.
Key Sections and Their Significance
The UB form is logically divided into sections that capture different aspects of the patient’s encounter and the services provided.
1. Provider Information (FL 1-8)
This section identifies the facility submitting the claim.
- FL 1: Provider Name, Address, and Telephone Number: This must be the legal name and address of the billing facility.
- FL 4: Type of Bill: This is a crucial 3-digit code.
- Digit 1: Type of Facility (e.g., ‘1’ for Hospital)
- Digit 2: Type of Care (e.g., ‘1’ for Inpatient, ‘3’ for Outpatient)
- Digit 3: Frequency Code (e.g., ‘1’ for Admit thru Discharge, ‘7’ for Replacement of Prior Claim)
- FL 5: Federal Tax Number: The facility’s Employer Identification Number (EIN).
- FL 7: Medicare Provider Number: The facility’s Medicare number, if applicable.
- FL 8: Patient Control Number: A unique identifier assigned by the facility for internal tracking.
2. Patient Information (FL 9-17)
Accurate patient demographics are paramount for proper identification and claim processing.
- FL 9: Medical Record Number: The patient’s unique identifier within the facility’s system.
- FL 12-16: Patient Name, Birth Date, Sex, Address: Ensure this matches the patient’s insurance card and medical records exactly.
- FL 17: Admission Date, Hour, Type, Source:
- Admission Date: The date the patient was formally admitted.
- Admission Hour: The hour of admission (e.g., ’01’ for 1 AM, ’13’ for 1 PM).
- Admission Type: (e.g., ‘1’ for Emergency, ‘2’ for Urgent, ‘3’ for Elective).
- Admission Source: (e.g., ‘1’ for Physician Referral, ‘4’ for Transfer from Hospital).
3. Condition, Occurrence, and Value Codes (FL 18-41)
These fields provide critical context for the services rendered and can significantly impact reimbursement.
Condition Codes (FL 18-28)
These 2-digit codes describe conditions or events that apply to the entire bill.
- Example: ’20’ (Beneficiary Requested Billing), ’04’ (Hospice), ‘G0’ (No-Fault Auto Accident).
- These codes inform the payer about special circumstances that might affect coverage or processing.
Occurrence Codes & Dates (FL 31-34)
These 2-digit codes identify specific events and their dates relevant to the claim.
- Example: ’01’ (Accident/Illness Date), ’04’ (Date of Admission), ’11’ (Onset of Symptoms).
- Each code is paired with a specific date.
Occurrence Span Codes & Dates (FL 35-36)
These codes identify a range of dates for specific events.
- Example: ’70’ (Qualifying Stay Dates), ’74’ (Prior Stay Dates).
- Each code is paired with a “From” and “Through” date.
Value Codes & Amounts (FL 39-41)
These 2-digit codes identify monetary amounts or values not covered by revenue codes.
- Example: ’01’ (Coinsurance Amount), ’02’ (Deductible Amount), ’31’ (Patient Liability).
- These are crucial for calculating patient responsibility and coordinating benefits.
4. Service Line Details (FL 42-49)
This is the heart of the claim, detailing the services provided.
FL 42: Revenue Code
This 4-digit code identifies the specific department or type of service provided. It’s a fundamental element of institutional billing.
- Example:
- 0300: Laboratory – General Classification
- 0450: Emergency Room – General Classification
- 0250: Pharmacy – General Classification
- 0110: Room & Board – Private (Non-Medical)
- Each line item on the claim must have a corresponding revenue code.
- Incorrect revenue codes are a frequent cause of denials. For a deeper dive, consult official CMS manuals or our guide on revenue code mastery.
FL 43: Revenue Code Description
A brief description of the service corresponding to the revenue code.
FL 44: HCPCS/CPT Codes
These codes describe the specific procedures, services, or supplies provided.
- For outpatient services, CPT codes are typically used.
- For inpatient services, ICD-10-PCS codes are used for procedures, while CPT may be used for professional components.
- Ensure the CPT/HCPCS code aligns with the revenue code. For instance, a CPT code for a lab test should be under a 030X revenue code.
FL 45: Service Date
The date the service was rendered.
FL 46: Units of Service
The quantity of the service provided (e.g., number of lab tests, hours of therapy).
FL 47: Total Charges
The total charge for that specific line item.
FL 48: Non-Covered Charges
Charges for services not covered by the payer.

- FL 57: Other Provider ID: Any other provider identification number required by the payer.
- FL 58: Insured’s Name: The name of the policyholder.
- FL 59: Insured’s Relationship to Patient: (e.g., ’18’ for Self, ’19’ for Spouse).
6. Diagnosis and Procedure Information (FL 66-75)
Accurate coding is paramount for medical necessity and reimbursement.
FL 66: Diagnosis Codes (ICD-10-CM)
These codes describe the patient’s medical conditions.
- Principal Diagnosis: The condition chiefly responsible for the admission.
- Other Diagnoses: Co-existing conditions that affect treatment or length of stay.
- Ensure all diagnoses are supported by medical record documentation.
FL 74: Principal Procedure Code & Date
For inpatient claims, this is the main surgical or diagnostic procedure performed.
- Uses ICD-10-PCS codes for inpatient procedures.
- For outpatient, CPT codes are used in FL 44.
7. Attending Physician and Other Provider Information (FL 76-79)
Identifies the healthcare professionals involved in the patient’s care.

8. Remarks and Other Information (FL 80-81)
FL 80: Remarks
Used for additional information required by the payer or to clarify specific aspects of the claim.
FL 81: Code-Code
This field is highly versatile and can be used for various purposes depending on payer requirements, such as:
- External authorization numbers.
- Specific claim-related identifiers.
- Often used for reporting specific data elements not captured elsewhere.
Understanding the specific use of box 19 on a ub-92 ub form (which corresponds to FL 81 on the UB04) is critical as it’s often payer-specific. Always refer to the payer’s billing manual for guidance on its use.
Addressing “What is Code 92?”
The query “what is code 92” can be ambiguous as there isn’t a single, universally recognized “code 92” that applies across all fields of the UB form. However, the number ’92’ can appear in various contexts:
- Condition Code 92: On the UB04, Condition Code ’92’ is used for “Claim for a beneficiary who is a qualified Medicare beneficiary (QMB) and is enrolled in a Medicare Advantage (MA) plan.” This is a specific scenario for Medicare beneficiaries.
- Revenue Codes: While there isn’t a 0092 revenue code, you might encounter codes like 0492 (Cardiac Catheterization) or 0792 (Labor Room/Delivery Room). The ’92’ here is part of a larger classification.
- Occurrence Codes/Value Codes: It’s less common for ’92’ to appear as a standalone occurrence or value code, but specific payers might have unique requirements.
When encountering “code 92,” it’s essential to clarify which field or context it refers to. In most cases, if it’s not a condition code, it’s likely a specific internal tracking code or a partial reference to a larger code. Always consult official coding manuals or payer guidelines for definitive answers.

Common Denial Codes & Step-by-Step Appeal Instructions
Denials are an inevitable part of medical billing, but effective appeal strategies can significantly recover lost revenue. Understanding common denial codes and having a structured appeal process is critical.
Understanding CARC and RARC Codes
Denial reasons are typically communicated using two sets of codes:
- Claim Adjustment Reason Codes (CARC): Explain why a claim or service line was paid differently than billed (e.g., denied, reduced).
- Remittance Advice Remark Codes (RARC): Provide additional explanation for a CARC or convey information not covered by a CARC.
Common Denial Codes and Appeal Strategies
1. CARC CO-16: Claim/Service Lacks Information or Has Submission/Billing Error
- Meaning: The claim is missing required information, or there’s an error in how it was submitted. This is a broad category and often paired with a RARC for specifics.
- Common RARCs:
- M86: Missing/incomplete/invalid documentation.
- N11: Missing/incomplete/invalid group practice information.
- N265: Missing/incomplete/invalid patient relationship to insured.
- Step-by-Step Appeal:
1. Identify the Specific Error: Review the RARC and the original claim. Was a field left blank? Was a code incorrect? Was documentation missing?
2. Gather Missing Information/Correct Error: Obtain the necessary data from the patient’s chart, front desk, or provider.
3. Correct the Claim:
- If it’s a simple data entry error, resubmit a corrected claim (often with Type of Bill ‘XX7’ for replacement or ‘XX8’ for void/cancel, depending on payer rules).
- If documentation was missing, prepare an appeal letter with the supporting documents.
4. Write an Appeal Letter: Clearly state the original claim number, the denial reason (CARC/RARC), the correction made, and attach supporting documentation.
5. Submit Appeal: Follow the payer’s specific appeal instructions (e.g., online portal, mail, fax).
2. CARC CO-29: The Time Limit for Filing Has Expired
- Meaning: The claim was submitted after the payer’s filing deadline.
- Common RARCs:
- N270: The claim was not received within the required time frame.
- Step-by-Step Appeal:
1. Verify Filing Limit: Confirm the payer’s filing limit and the date the claim was originally submitted.
2. Identify Reason for Late Filing: Was there a system error? A natural disaster? A delay in receiving information from another payer (for secondary claims)?
3. Gather Evidence: Collect proof of timely submission (e.g., electronic submission report, certified mail receipt) or documentation supporting an exception (e.g., disaster declaration, proof of primary payer processing delay).
4. Write an Appeal Letter: Explain why the claim was late, provide evidence, and request an exception to the filing limit.
5. Submit Appeal: Attach all supporting documentation.
3. CARC CO-97: The Benefit for This Service Is Included in the Payment/Allowance for Another Service/
FAQ: Common Questions Answered
When is the UB92 form still used in medical billing?
While the UB92 form was largely superseded by the UB04 form in 2007, its relevance isn’t entirely diminished. In 2025, you might still encounter or need to understand UB92 for specific, albeit limited, scenarios. These include processing adjustments or appeals for very old claims originally submitted on a UB92, dealing with legacy systems that haven’t fully transitioned, or for educational purposes to understand the evolution of institutional billing. Some niche state programs or specific payers might also have unique requirements that reference UB92 standards, though this is increasingly rare. For the vast majority of current institutional claims, the UB04 is the mandated standard.
What are the key differences between UB92 and UB04 claim forms?
The UB04 form represents a significant evolution from the UB92, primarily driven by the need for more comprehensive data, compliance with HIPAA standards, and the transition to ICD-10 coding. Key differences include: the UB04 has 81 Form Locators (FLs) compared to UB92’s 76, allowing for more granular data capture. UB04 introduced mandatory fields for the National Provider Identifier (NPI) for all rendering and billing providers, Present on Admission (POA) indicators for diagnoses, and expanded sections for Condition Codes and Value Codes. It also refined patient status codes and was designed to be fully compatible with HIPAA 5010 transaction standards, making it better suited for electronic claims submission and the complexities of modern healthcare billing.
Where can I find a printable UB92 claim form PDF?
Finding a blank, printable UB92 claim form PDF for current submission purposes is challenging, as the UB04 is the universally accepted standard for institutional claims. Most medical billing software and clearinghouses only provide UB04 forms. However, if you need a UB92 form for historical reference, training, or to process an extremely old claim adjustment, you might find archived versions through resources like the National Uniform Billing Committee (NUBC) website, older medical billing textbooks, or by contacting specialized medical billing vendors who maintain historical forms. Always verify the form’s validity and acceptance with the specific payer before attempting any submission.
How do I complete the Type of Bill (TOB) field on a UB92 form?
The Type of Bill (TOB) field, typically a 3-digit code on the UB92 form (similar to FL4 on the UB04), is crucial for payers to understand the nature and sequence of the claim. Each digit conveys specific information:
- Digit 1 (Type of Facility): Identifies the type of institution submitting the bill (e.g., ‘1’ for Hospital, ‘2’ for Skilled Nursing Facility, ‘3’ for Home Health Agency).
- Digit 2 (Bill Classification): Specifies the type of care or patient status (e.g., ‘1’ for Inpatient, ‘2’ for Outpatient, ‘3’ for Emergency, ‘4’ for Clinic).
- Digit 3 (Frequency): Indicates the sequence of the bill for a specific patient stay or encounter (e.g., ‘1’ for Admit through Discharge, ‘2’ for Interim First Claim, ‘7’ for Replacement of Prior Claim, ‘8’ for Void/Cancel of Prior Claim).
Accurate completion of this field is vital for correct claim processing and reimbursement, as it dictates the billing rules and payment methodologies applied by the payer.
