Active Treatment vs. Maintenance Care: The Chiropractic Billing Line That Decides Every Claim
A patient walks in for their twelfth adjustment in three months. Repeat the same complaints area, the same general approach to the complaints. The chiropractor’s perspective: continuity of care. If you’re the payer who’s trying to read this claim, this could be interpreted as maintenance care, and maintenance care is where a lot of chiropractic reimbursement goes unnoticed.
This is not something in subtle print. This is the one line that can make or break a claim’s payability, denial, or review. This is where most practices don’t lose money without being doing something wrong clinically. They lose it because the difference is not clearly captured and properly documented to withstand scrutiny by a payer.
Two Categories, One Very Blurry Line
Active treatment indicates that the patient has been diagnosed with a condition that can be expected to improve through a course of treatment. The problem is measurable; the treatment plan is grounded in the problem, and there is a reasonable expectation of improvement in a reasonable time. This will be paid back to payers, such as Medicare.
During maintenance, it is a different ballgame. It is a patient who has reached a plateau or stabilization point, and the treatment is for maintenance of current function, not improvement. Maintenance care is not covered by Medicare. This is often the case with most commercial payers, even if they are more ambiguous in their published policies on where the line is actually drawn.
The issue is that these two types can be practically indistinguishable one visit to the next. The adjustment technique doesn’t change much. How the client’s condition has changed and if it is accurately documented.
Where Practices Get Caught Off Guard
Fraud and carelessness are not typically the weakest links. It’s momentum. A patient begins active treatment for an acute episode of low back pain, gets better over the course of 6-8 visits, and then continues weekly visits due to the effect the treatment has on them and the chiropractor’s belief that the care has value. No one makes the diagnosis, treatment goals, or the billing code change so that the patient is in maintenance. Claims continue to be issued that are exactly the same as the previous claims that were validly in treatment.
This is easily noticed by payers by analyzing visits. A claims algorithm does not require the clinician to mark it. As soon as the number of visits for one diagnosis reaches a certain number of visits without any new functional outcome measures, it is automatically flagged for review.
This is most clearly seen with the AT modifier when applied to Medicare claims to denote active treatment. Adding AT to a claim for which there is no evidence in the documentation is not a grey area. It’s one of the most frequently mentioned problems on chiropractic Medicare audits and is easily seen throughout a provider’s claims history.
What the Documentation Actually Needs to Show
Getting this right comes down to a few specific documentation habits that hold up under review.
Diagnosis must be clear and current, based on an objective finding and not simply a diagnosis carried over from several months ago that no longer applies to the patient.
Treatment goals must have measurable benchmarks. “Improve range of motion by x degrees,” or “Reduce pain from a 7 to a 3 on a functional scale” provides a reviewer with a form of progress check. A goal such as “continue care as needed” will be interpreted as maintenance, no matter what the code for the billed service is.
All notes must have some form of progress note, even a simple one. Become better, levelled off, or worse. A single statement could be the key to the success of a claim or to its being denied as being not medically necessary.
If a patient truly does “indicate” to go into maintenance care, the transition should be documented in a thorough fashion and should have a corresponding change in billing procedure. It’s important to remember that some payers have specific rules that still permit maintenance visits to be charged, but not necessarily expected to be reimbursed by insurance. This needs to be communicated to the patient and not assumed.
Why This Category Gets Audited So Frequently
The payment position of chiropractic is unique. However, with a surgical specialty, it is usually obvious that surgery is necessary, and this does not need to change from visit to visit. In a surgical specialty, however, the need for ongoing manual therapy is usually clear, and doesn’t have to be justified visit to visit. That is the reason that practices with frequent visits per patient are more likely to be audited than practices with relatively short treatment periods and clearly defined treatment episodes.
This is also the point where a lot of practices realize their internal billing process wasn’t built to catch this shift in real time. Chiropractic billing services that specialize in this specialty tend to build active-treatment-to-maintenance tracking directly into their claims review process, flagging visit counts and stagnant progress notes before a payer’s algorithm does it for them. Catching the transition internally, before it becomes a pattern across dozens of claims, is a fundamentally cheaper problem to solve than responding to a post-payment audit months later.
The Bottom Line for Practices
This separation isn’t changing, and payers are becoming more “automated” in identifying this distinction. The chiropractors who are making long-term patient relationships are not the ones who don’t make money. They are the ones who see the change from active care to maintenance and adjust their billing strategies when that change occurs, instead of keeping visit twelve the same as visit two.
