CO 256. It's a denial code that can make any biller's eyes roll. Why? Because it points directly to the heart of the managed care aggravation: contract terms that decide what's payable and what's not. "Service not payable per managed care contract" sounds straightforward, but digging into the details can reveal a tangle of stipulations and clauses that feel anything but simple.
Understanding CO 256
CO 256 means a claim was denied because the service in question isn’t covered under the managed care agreement in place. It’s a reminder that when it comes to managed care contracts, the devil is truly in the details. These contracts are not one-size-fits-all — each payer might have different stipulations, and those can even vary from one specialty to another.
Managed care contracts dictate the specifics of coverage, including which services are payable, under what circumstances, and at what rates. When you see CO 256, it’s a signal that either the service provided wasn’t covered as thought, or perhaps, there’s a misunderstanding of the terms. Here’s what to do when faced with this denial.
Step-by-Step: Tackling CO 256
Review the Contract
First things first — read the contract. Sounds basic, but contracts can be lengthy, and it’s easy to overlook nuances. Managed care contracts will list covered services, exclusions, pre-authorization requirements, and any limitations. Look for the section detailing specific services and conditions. Is the denied service excluded from coverage? Is there a cap on the number of times such a service can be billed?
Cross-Check with Patient Coverage
Next, verify the patient's eligibility and plan details. Even within a single payer, plan specifics can differ. Use the payer’s portal to confirm the service is indeed not covered under the patient’s plan. These portals are notorious for their quirks — slow load times or buried information — but persistence here pays off.
Verify Authorization
Did the service require pre-authorization? Managed care contracts often require this step for certain services, and missing it is a surefire path to denial. Check the authorization status in the payer’s system. If overlooked, appeal the denial by providing retroactive documentation if your contract allows it.
Payer Communication
When things aren’t adding up, pick up the phone. Contacting the payer can often shed light on why CO 256 was applied. Be prepared for lengthy hold times, and make sure to have all the claim details on hand. Sometimes there’s an internal error at the payer’s side — not unheard of, unfortunately.
Appeal if Necessary
If you're certain the service should be covered, file an appeal. This isn’t a quick process — prepare for it to be a drawn-out battle — but if the contract terms support your position, it’s worth pursuing. Include contract excerpts, any correspondence with the payer, and all relevant documentation.
Common Pitfalls and How to Avoid Them
Assuming Coverage
Assumptions are the enemy. Never assume a service is covered just because it’s a routine procedure or has been covered in the past under a different plan. Payer-specific quirks and unique plan configurations mean past coverage doesn’t guarantee future payment.
Incomplete Contract Reviews
Skimming contracts rather than digging into their depths leads to unpleasant surprises. An incomplete understanding of the terms can result in repeated denials. Develop a habit of thorough contract review — it’s tedious but necessary.
Ignoring Plan Changes
Managed care plans are not static. Payers update them annually, at minimum — sometimes more frequently. Keep abreast of these changes to avoid denials stemming from outdated knowledge.
Turning Denials into Opportunities
CO 256 denials, annoying as they are, offer a learning opportunity. Each denial is a chance to better understand contract intricacies and to prepare for future claims. By thoroughly dissecting the denial and its causes, billing teams can refine their processes — reducing the frequency of similar denials down the road.
Final Thoughts
In the world of medical billing, mastery over managed care contracts equates to fewer denials, smoother claim processes, and ultimately, better cash flow for the practice. CO 256 might be a headache, but it doesn’t have to be a dead end. With careful contract review and diligent follow-ups, these denials can be tackled effectively. Prepare now, and next time CO 256 pops up, it won’t be a crisis — just another claim to manage.
