Coding is just one part of the larger ambulatory surgery center (ASC) revenue cycle, but it’s incredibly important to get right. Proper coding ensures billing and reimbursement proceed seamlessly; however, even minor coding errors can lead to compliance issues, payment delays, and claim denials, directly affecting the bottom line.
Coding sits at the intersection of clinical accuracy and revenue protection. To help you ensure coding compliance, we’ve put together the following ambulatory surgery center coding guidelines. Discover the key guidelines to follow, the coding compliance challenges ASCs face the most, some strategies to help avoid costly errors, and why outsourcing may be the best route to take.
The first step to achieving accurate, efficient coding is to build a clear, up-to-date reference list of codes. This should include a list of Current Procedural Terminology (CPT), Healthcare Common Procedure Coding System (HCPCS), and the International Classification of Diseases, Tenth Revision (ICD-10) codes.
CPT, HCPCS, and ICD-10 codes identify the items and services associated with certain designated health services that may qualify for certain exceptions. Accurately submitting codes is essential for reimbursement, and a simple error could lead to denials or financial penalties. This is why it’s key to ensure that staff document the correct procedures and submit the proper codes.
The Centers for Medicare and Medicaid Services (CMS) maintains and updates these codes on an annual basis. As such, your ambulatory surgery center coding guidelines must be updated accordingly. You can find up-to-date codes and information on relevant coding updates here for CPT and HCPCS codes and here for ICD-10 codes.
Unfortunately, commercial payers often have coding rules that differ from CMS. This can be difficult and complex to remember and navigate, so it’s often necessary to create payer-specific ASC billing guidelines that explain the coding rules for each payer. Similar to CMS, it’s important to keep these guidelines up-to-date as payers adjust their rules or expand their code lists; though, the frequency of such updates may be more irregular. As such, check payer rules quarterly and inform and train staff of any changes as soon as possible to ensure the revenue cycle continues to run smoothly.
Additionally, you must use the correct modifiers on codes. Modifiers amend certain codes and inform payers on how to adjust payments for specific resources and services. Train to understand the correct modifier usage, including when to use them, how to document them, and how to sequence codes to avoid errors.
Finally, documentation must align with coding rules. Documentation best practices should be shared across the ASC, so everyone—from coders to surgeons and physicians—is aligned on their importance. Accurate clinical notes and operative reports support accurate billing and coding, while unnecessary shorthand or vague documentation can lead to claims denials.
Following these ASC coding guidelines is key to ensuring accurate coding, but it’s also essential for compliance. When your documentation and reference material is up-to-date and organized, audits won’t be intimidating, and they’ll go faster and smoother. This helps you avoid issues that could slow reimbursement and enables your revenue cycle to run like a well-oiled machine.
Without clear, strict ambulatory surgery center coding guidelines, your facility may face a compliance bottleneck that reduces revenue. Here are some common compliance challenges to watch for:
Accurate coding requires a solid foundation and framework of support. ASC coders need comprehensive resources they can reference on their own, regular training to stay up to date with coding changes and payer rules, and clear documentation to help them assign codes to procedures and services.
Without support, coders may feel pressured to make educated guesses or work faster than necessary, which can lead to coding errors, such as upcoding, undercoding, or misusing modifiers. This can negatively affect the bottom line and complicate compliance.
ASC coders rely on documentation to accurately itemize procedures and services and apply the correct codes. Sloppy notation or incomplete operative reports from surgeons can confuse coders, making it unclear what to bill and why. This can lead to unnecessary claim denials, lengthen the time to receive reimbursement, and burden staff with the need to clarify details for an appeal.
On the coding side, it’s also critical to document everything, including when a payer was billed, what was billed, and why. This can streamline compliance audits and ensure all medical records are accurate and up to date.
As your ASC grows and your network expands, you’ll likely have to contend with more payers, each with its own set of ambulatory surgery center coding guidelines. Without proper planning and upkeep, these rules can quickly become disorganized and challenging to navigate, even for the most diligent of coders.
Whether it’s applying the wrong modifier, sequencing codes incorrectly, or billing the wrong code for a specialized procedure, these errors can add up, hurt the bottom line, and even strain relationships with payers who don’t want to deal with this type of compliance headache.
Continuous improvement is key in the ASC setting, where the care landscape is constantly evolving. If you don’t set aside time to conduct regular coding audits, you’ll miss opportunities to improve key metrics tied to the financial success of the organization.
Make it a point to review coding performance regularly. Internal audits can also help you prepare for the real thing when you need to demonstrate the accuracy of your reporting and find important information.
While the challenges of billing compliance can be many and intimidating, you can use the following strategies to reduce errors:
Coding is not a one-and-done skill; it must be continually honed. This is because codes and payer-specific rules change frequently, often annually. Plus, as healthcare evolves, new regulations may be rolled out that affect coding best practices and requirements.
This being the case, it’s best to conduct ongoing coder training to reinforce standards, emphasize the importance of precision, and update staff on coding changes.
Technology can support accurate coding in several ways. For example, coding software can streamline the coding process and ensure the correct codes are associated with the right items and services. Integration with electronic health records can further simplify coding by ensuring codes align with medical records, which should reflect the most up-to-date documentation and patient data available.
ASC-specific coding software can also help establish billing and coding policies and store all reference material in one centralized platform, which supports accurate coding by making it easy to keep track of relevant rules and requirements.
One of the best ways to measure coding performance is to conduct internal reviews and audits regularly, ideally once or twice a year. This allows you to set metrics for coding accuracy and other key performance indicators and compare hard data against them. This creates accountability for staff and prepares your organization for official audits.
Monitoring tools can also help by tracking coding and billing performance, enabling ongoing identification of areas for improvement.
All the best practices and guidelines won’t matter if they’re not adopted. To help encourage adoption, foster a compliance-driven culture by emphasizing the importance of precision—and make it a point to apply these standards across all roles, from coders to surgeons and beyond.
When everyone is on the same page and understands that accurate dictation and documentation are paramount, you can enjoy a more streamlined, compliant, and error-free revenue cycle.
Achieving compliance is possible if you have the time and resources to develop comprehensive ASC coding guidelines and provide the oversight needed to ensure performance metrics are met and continually improved. However, not every ASC is in that privileged position.
ASC billing and coding require a certain level of expertise. Even staff who have worked in other healthcare organizations may not have the experience required to accurately code for ASC-specific payers. It can be confusing, complex, and difficult to navigate for numerous reasons, and in the face of financial penalties and high-pressure revenue cycle needs, it can feel incredibly intimidating to manage.
However, it doesn’t have to be this way. Outsourcing is a powerful option for ASCs that don’t want to spend time managing the complexities of regulatory compliance. With the right partner, ASCs can be assured that their coding and compliance needs are met by experts, freeing up their time to focus on what they do best: delivering safe and effective patient care.
