In the Aug. 1, 2014 issue of Dynamic Chiropractic, I reviewed some of the literature demonstrating the role of the chiropractic adjustment in post-concussive care.1 A year later, I presented a series of brief cases demonstrating patient improvement in reverse digit span – an outcome measure related to attention span – under chiropractic care.2 This series included patients with and without concussion. In the process of preparing these articles, as well as organizing material for postgraduate courses, I naturally found myself reviewing much of the biomedical and chiropractic clinical literature relevant to concussion and the vertebral subluxation complex (as defined in Redwood, 1997).3 Let's try a few simple thought experiments and then discuss why a new classification term – the concussion-subluxation complex – may be warranted.
Two Thought Experiments
Try these two thought experiments (experiments conducted entirely within the confines of your own mind); I believe the results will speak for themselves.

Recent laws in New Jersey and California represent a disturbing trend that will negatively impact a practice’s ability to collect monies from patients, as well as expose them to significant penalties if the practice does not follow the mandatory guidelines to a T. Please be aware that a similar law may be coming to your state. The time to act is before the law is passed.

With estimates showing over 30 million Americans affected by peripheral neuropathy – and a significant portion underdiagnosed – it’s increasingly likely that chiropractors are already treating these patients. What’s missing is structured recognition, comprehensive management and targeted tools to slow progression, improve function and support systemic health.

Each year, ICD-10-CM is updated on Oct. 1. For 2026, there are 74,179 total codes, with 487 additions, 28 deletions and 38 revisions. Code changes are based on date of service, not the claim submission date. Services performed on/after Oct. 1 must use the new codes. While no changes affect the common spinal or extraspinal codes most frequently used by DCs, several updates may still affect your claims – particularly for comorbidities, referred pain, or trauma cases. | Digital Exclusive
