This blog describes the process for coding patients on with Eliquis based on the coded conditions such as atrial fibrillation, DVT, and pulmonary embolism. It discusses the nuances of documentation, specificity of codes, and the longitudinal anticoagulant codes. It also touches on coding and billing best practices, frequent mistakes, compliance, and reimbursement and audit risk.
Modern healthcare has made it essential for medical coding to be precise. With positive patient outcomes in mind, healthcare systems must be compensated for the work being done. Eliquis is a blood thinner that is prescribed to prevent and treat life-threatening blood clots. Healthcare workers and medical coders face a challenge when dealing with blood thinner prescriptions since those prescriptions do not have a specific ICD code. This guide seeks to answer this question while detailing how to tackle the ICD-10 codes that relate to prescriptions for Eliquis, the diagnosis codes, the documentation needed, the associated billing processes, and the issues that can arise when billing for blood thinner prescriptions.
Eliquis and Its Medical Purpose
Definition and Purpose
Eliquis is an oral blood thinner and a Direct Factor Xa Inhibitor. By Direct Factor Xa Inhibiting, Eliquis prevents the blood from clotting, which therefore decreases the chance for a stroke or a systemic embolism. Patients that have Atrial fibrillation, unless it is from a heart valve, and patients with deep vein thrombosis (DVT) or those with pulmonary embolism (PE) conditions are prescribed the anticoagulant, Eliquis. Eliquis has multiple uses in the medical field. In such case, it is a blood thinner that has multiple clinical indications and therefore coding guidelines cannot be adhered to. ICD-10 coding systems are designed to identify and describe the uses blood thinners without leaving gaps in the system.
Why There is No ICD-10 Codes for Eliquis?
Eliquis is a newer prescription medication that must be treated the same as other prescriptions for the purpose of coding. ICD-10-CM does not code based on medications, and instead, relies on documenting the patien’s diagnosis(es). If prescription medication is used on a long term basis, ICD-10 does allow for a code to be used to indicate long term prescription medication use. From an insurance billing persepctive, the above is justified. Insurance uses diagnosis codes to determine if a prescription is medically necessary. If the diagnosis code is not appropriate, the insurance will deny the claim for anticoagulant therapy.
Common ICD-10 Codes Linked to Eliquis Use
Atrial Fibrillation
Eliquis is frequently used for the treatment of Atrial Fibrillation as it is one of the most common reasons for which this medication is prescribed. Atrial Fibrillation is a sustained irregular heartbeat and increases the risk of a stroke. There are several ICD-10 codes for Atrial Fibrillation as there are several code options for varying types of Atrial Fibrillation.
For instance, an epithelium with a diagnosis of paroxysmal atrial fibrillation will be given a code of I48.0 as opposed to an atrial fibrillation diagnosis of persistent I48.1 or chronic I48.2 or unspecified that is given a code of I48.91. Clinically, the detail is documented, and codes are easy to determine.
Deep Vein Thrombosis (DVT)
A common condition that Eliquis is prescribed to treat and prevent is deep vein thrombosis (DVT) which occurs when there is a formation of blood clots in deep veins and is usually found in the legs. ICD-10 coding for DVT requires detailed determination of the position, location, and even the laterality of the clot.
For instance, I82.401 is used for acute embolism and thrombosis of unspecified deep veins of the right lower limb. Other specific codes are preferable when the documentation allows it, as it may enhance the accuracy of the claim and the reimbursement.
Pulmonary Embolism (PE)
A pulmonary embolism is a serious condition that occurs when a blood clot lodges in a blood vessel of the lungs. Eliquis is commonly prescribed for this condition both for treatment and for the prevention of possible recurrence.
To report PE without acute cor pulmonale, coders use the ICD-10 code I26.99. Depending on the complexity, severity, and the associated complications of the condition, further codes may be necessary.
Long-Term Anticoagulant Therapy
In the case of Eliquis, which is indicated for long-term use, coders are required to assign an additional ICD-10 code that specifies long-term anticoagulant therapy. The most frequently used code in this instance is Z79.01.
The use of this code is in addition to the primary diagnosis and is meant to illustrate clinical necessity and more fully describe the patient’s situation.
Documentation Requirements for Accurate Coding
The most accurate ICD-10 coding is the result of rigorous coding and thorough clinical documentation. The provider’s clinical notes must specify which diagnosis is being treated, the indication for prescribing Eliquis, and whether the therapy is short-term or long-term.
In the case of atrial fibrillation, for example, the notes should indicate the type, whether it is paroxysmal, persistent, or chronic. In the case of DVT or PE, the notes should indicate the location, severity, and whether the condition is acute or chronic.
Lastly, documentation should include relevant details in the patient’s history, such as previous occurrences of clotting, bleeding risks, or changes in medication. Good documentation will improve coding accuracy and help with reimbursement.
Billing Guidelines and Best Practices
Linking Diagnosis to Treatment
One of the most important responsibilities concerning billing for Eliquis care, is to ensure that the diagnosis code justifies the medical necessity of the prescribed anticoagulation therapy. This is critical, and without it, claims will be denied.
An example is without documentation of an active atrial fibrillation, DVT or PE, it is inappropriate to justify an Eliquis prescription and for billing purposes, will structure an inappropriate and damaging gap.
Correct Application of Secondary Coding
Secondary coding such as Z79.01, which indicates the patient is on long-term anticoagulation therapy, should be employed as such to indicate and justify chronic treatment, especially for chronic conditions.
Secondary coding, even if it is not the primary diagnosis, will increase the accuracy and complement the claim.
Specificity in Coding is Important
The most detailed available ICD-10 code is necessary. The more specific the coding is during billing, the better the claims will be in terms of reimbursement. The more generic the codes are when it comes to documentation, the more likely the claim will be denied.
This is to say that there is a predetermined set of coding guidelines that the patient’s provider will choose to apply based on the documentation described.
Common Coding Mistakes and How to Avoid Them
Trying to Code for Eliquis
One of the most common coding errors is trying to code for Eliquis. This is a medication that is not included in ICD-10, and as such, it cannot be done.
Excluding Long-Term Anticoagulant Code
Another frequent mistake is not adding the long-term anticoagulant code to the documentation when it is warranted. Missing Z79.01 can be detrimental to the overall quality of the documentation and can impact the ability to be reimbursed.
Using Unspecified Codes
In addition, some coders use unspecified codes when there are clear details available. It can lead to coding deficiencies, increase the risk of audits and slow the payment process.
Thus, to prevent the above problems, coders need to be sure the documentation sufficiently supports the claim and all comorbid conditions are incorporated, and warranted codes are used.
Specific Coding Situations
Post-Surgical Anticoagulation
After some surgical procedures, the use of Eliquis may be warranted to prevent clotting. For these situations, codes for the post-operative period and initiation of the anticoagulant therapy are required.
Order of the codes is very important to depict the clinical picture accurately and obtain reimbursement for the care.
Bleeding Complications
Eliquis can lead to bleeding complications. Therefore, when such complications occur, it is imperative to apply additional ICD-10 codes for the adverse event.
In relation to coding and billing outcomes, the documentation for the bleeding should specify whether it is related to the use of anticoagulants.
Anticoagulant Transition
Anticoagulants can be changed for various clinical reasons. When it is necessary for a patient to transition from one anticoagulant to another, thorough documentation of the changes and rationale is required.
Coders are responsible for including all relevant diagnoses and details of the treatment to ensure accurate reimbursement and continuity of care.
Compliance and Audit Considerations
Coding compliance is crucial for avoiding monetary penalties and delays in payment for services rendered. Certainly correct coding for Eliquis and services associated with the drug constitutes compliance with payer regulations and helps avoid liability for audits.
Compliance risk is enhanced in the absence of continuous education and training, poor documentation, and ineffective claim coding. Effective compliance audits starts with record keeping and supportive documentation that is comprehensive and effectively connects the dots between a coder, a provider and the payer upon review.
Conclusion
In coding for Eliquis, the coder must have a good command of the relevant ICD 10 codes and the associated clinical condition. The coder must know that there is no code for the drug Eliquis so the coder must ensure there is an appropriate diagnosis code and appropriate supplemental codes with long term anti-coagulant therapy. Compliance is must and with good documentation, correct coding, avoiding the pitfalls, and the coding professional along with the provider can ensure the claim is paid in full. As anti-coagulation therapy is an integral part of patient management, the coder’s proficiency is an indication of the organization’s financial profitability.
Make An Appintment With A2ZFAQs
No, there is not. Codes are assigned for the conditions being treated, including but not limited to, atrial fibrillation, deep vein thrombosis, and pulmonary embolism.
Z79.01 reflects the chronic (current) use of anti-coagulants and is used to describe the primary condition that is being treated.
Documentation is the foundation of coding; it supports the medical necessity, and it is a way of avoiding claim denials and an increase in the audit risk. Proper documentation also improves reimbursement accuracy.
Yes. If a patient has multiple conditions, ie. atrial fibrillation and history of DVT, or is prescribed long term anti-coagulants, more than one code is warranted.
Common errors include attempting to code the medication, not adding the longterm use code, and using an unspecified diagnosis code when more specific ones are available.
