Background

Christy Coll sued Dr. John Kelly, a licensed chiropractor, for professional negligence after seeking treatment for neck and shoulder pain. Coll alleged that Dr. Kelly took an X-ray that was partially obscured by her necklace and failed to retake a clear image before performing a spinal manipulation. Coll claimed she experienced immediate sharp pain and was later diagnosed with a serious spinal infection (discitis/osteomyelitis) in the area that had been obscured on the X-ray.

To support her malpractice claim, Coll attached an expert affidavit from Dr. Jeremy Royal, a musculoskeletal radiologist. Dr. Royal opined that Dr. Kelly breached the standard of care by relying on an obscured X-ray and that the subsequent spinal manipulation may have caused or worsened Coll’s infection. Dr. Kelly moved to dismiss the lawsuit, arguing that Dr. Royal, as a medical doctor, was not qualified to provide an expert opinion against a chiropractor under Georgia law. The trial court agreed and dismissed the complaint.

The Court’s Holding

The Court of Appeals of Georgia affirmed the trial court’s dismissal. The court’s decision centered on Georgia’s statutory requirements for expert affidavits in professional malpractice cases. Under OCGA § 9-11-9.1 and § 24-7-702, an expert providing an affidavit must be a member of the “same profession” as the defendant. The court observed that Georgia statutes explicitly list “medical doctors” and “chiropractors” as distinct and separate professions.

Because Dr. Royal is a medical doctor (a radiologist) and Dr. Kelly is a chiropractor, the court concluded they are not members of the same profession. Therefore, Dr. Royal was not qualified to offer expert testimony on the standard of chiropractic care. The court rejected Coll’s argument that a different rule should apply because the case involved taking an X-ray, a procedure common to both medicine and chiropractic. It held that the “same profession” requirement is absolute for an expert affidavit, regardless of any overlap in procedures. As Coll’s complaint was not supported by a valid expert affidavit, its dismissal was mandatory under Georgia law.

Key Takeaways

  • In a Georgia professional malpractice case, the plaintiff’s expert witness must be from the exact “same profession” as the defendant.
  • Georgia law considers medical doctors and chiropractors to be separate professions for the purposes of expert testimony.
  • A medical doctor cannot serve as a qualified expert witness against a chiropractor in a malpractice lawsuit, even if the alleged negligence involves a procedure (like an X-ray) that both professions perform.
  • Failing to file a statutorily compliant expert affidavit with the initial complaint will lead to the dismissal of the case.

Why It Matters

This decision reinforces the strict “same profession” rule for expert witnesses in Georgia malpractice litigation, highlighting a critical requirement for plaintiffs. It clarifies that the legal distinction between professions like medicine and chiropractic is rigid, even when their practical procedures overlap. Attorneys and plaintiffs must ensure their chosen expert precisely matches the defendant’s professional category as defined by statute. The ruling underscores the importance of procedural compliance and significantly narrows the pool of potential experts in cases where professional practice areas intersect, potentially making it more challenging to bring certain malpractice claims.
