Code Description

ICD-10 B19 is a used to indicate a diagnosis of viral hepatitis, unspecified.

Key Diagnostic Point:

Viral hepatitis, unspecified.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity
Rating: Moderate Factors: 1. Specificity of Diagnosis: ICD-10 code B19 refers to the non-specific category of Unspecified Viral Hepatitis. This lack of specificity can increase complexity because it does not give precise information about the type or stage of the disease. Healthcare providers often favor more specific codes for precise treatment and billing. 2. Compliance with Coding Standards: Coding standards demand specificity. A less specific code like B19 might indicate non-compliance, thus increasing complexity. 3. Non-billable Code: B19 is a non-billable code, implying it cannot be used for reimbursement claims. This increases complexity because adjustments may need to be made to account for treatments and services associated with a non-billable code. Audit risks: 1. Coding Audits: Lack of specificity could raise red flags during coding audits. Auditors may perceive this as a potential area of non-compliance with coding standards. 2. Third-party Payor Denials: Claim denials could increase because the code is non-billable. Insurers generally reject bills with non-specific or non-billable codes as these do not provide sufficient documented evidence for the services rendered. 3. Legal implications: Non-compliance to the ICD-10 Coding Standards and Guidelines could potentially have legal implications if it is perceived that the healthcare provider is systematically using less specific codes. In conclusion, ICD-10 code B19 introduces moderate complexity related to its non-specific nature and non-billability. Nevertheless, it is duly important to ensure proper coding practices are in place to avoid coding audits, insurance denials, and legal implications.

Specialty Focus

Medical Specialties

ICD 10 code B19 is definitely a billable code, designated for unspecified viral hepatitis without hepatic coma. It is commonly used in the diagnosis and treatment of patients suffering from various types of viral hepatitis. However, the code can't provide specific details like the type of hepatitis virus involved. The top three major medical specialties that often use this code include Gastroenterology, Infectious Disease, and Internal Medicine. 1. Gastroenterology: These specialists treat conditions related to the digestive system which includes the liver. Clinical scenario: A patient presents with symptoms like jaundice, fatigue, dark urine, and abdominal pain. Tests show inflammation of the liver, but further detailed tests to identify the specific viral cause are yet to be performed. The gastroenterologist, in this case, might use the B19 code. 2. Infectious Disease: This area of specialty manages diseases caused by viruses, bacteria, fungi, parasites, etc. Clinical Scenario: A patient with a history of drug abuse comes in with fever, fatigue, and loss of appetite. The infectious disease doctor suspects viral hepatitis but doesn't yet know which specific virus is involved. They would use the B19 code. 3. Internal Medicine: These general medicine physicians often encounter a wide variety of diseases, including viral hepatitis. Clinical Scenario: A patient presents to an internal medicine clinic with generalized malaise, nausea, right upper quadrant pain, and jaundice. The physician runs some tests which suggest hepatitis, but the specific form of viral hepatitis is yet to be confirmed. They can utilize the B19 code in this context until more specific results are available. It is important to remember that the B19 code signifies 'unspecified' viral hepatitis and will often be further clarified or replaced by a more specific code once further diagnostic test results are available.

Coding Guidelines

Inclusion Criteria

Use B19 When
  • The ICD
  • 10 code B19 is a non
  • billable code
  • This indicates that the code is not applicable to any procedure that is billed to the 'medical beneficiary's medical health insurance that is apart of HIPAA standard transactions
  • The ICD
  • 10 CM B19 is a diagnosis code, not a procedure code, therefore it is not billable
  • Here are the characteristics regarding the coding guidelines of ICD
  • 10 code B19:

Related CPT Codes

I'm sorry but the task is not possible in the given context. CPT (Current Procedural Terminology) codes are used to identify procedures and services rendered by providers, while ICD-10 (International Classification of Diseases) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in conjunction with hospital care. However, B19 is a non-billable superbill code in ICD-10, meaning it serves as a generalized umbrella for other, more specific codes that fall underneath it. As a non-billable code, it wouldn't have direct corresponding CPT codes. B19 is specifically related to Unspecified Viral Hepatitis, so it would likely fall under more specific diagnoses which would then be paired with procedures related to the treatment of specific forms of viral hepatitis. For specific treatment codes, you would need to look at codes for the specific form of viral hepatitis (e.g., B19.10 for Unspecified viral hepatitis B without hepatic coma, or B19.20 for Unspecified viral hepatitis C), and pair those with their relevant procedure codes. Give me a more specific ICD-10 code, and I'd be happy to find you some common corresponding procedure codes.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The International Classification of Diseases, Tenth Revision (ICD-10) is a coding system used to classify and code all diagnoses, symptoms, and procedures recorded in conjunction with hospital care in the United States. Transitioning from ICD-9 to ICD-10 brought about several changes to billing and coding processes, including for the B19 diagnosis code (also known as ICD-10-CM B19) commonly used for unspecified viral hepatitis.
1. Specificity: ICD-10 has a greater level of specificity compared to its predecessor, ICD-9. For instance, code B19 is non-billable and therefore considered invalid, as it is too general. However, ICD-10 allows healthcare providers to code for specific type of unspecified viral hepatitis such as B19.9.
2. Reimbursement: Under ICD-10, reimbursement can be heavily influenced by the level of specificity used in coding. General codes like B19, which are considered non-billable, may result in non-payment or delayed payment, as insurers often require more specific diagnosis codes. Therefore, it's essential to use the right level of specificity, like B19.9, to ensure reimbursement.
