2026 ICD-10-CM Updates for Chiropractic Practices

Samuel A. Collins  |  DIGITAL EXCLUSIVE

Effective Date: Oct. 1, 2025.

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.

Key rule: Code changes are based on date of service, not the claim submission date. Services performed on/after Oct. 1 must use the new codes.

Areas Impacting Chiropractic Documentation

While no changes affect the common spinal or extraspinal conditions most frequently used by DCs, several updates may still affect your claims – particularly for comorbidities, referred pain, or trauma cases.

Pain & Tenderness (R-Codes)

Deleted: R10.2 Pelvic and perineal pain

Added:

  • R10.20 – R10.23 Pelvic/perineal pain (unspecified, right, left, bilateral)
  • R10.24 Suprapubic pain
  • R10.85 Abdominal pain, multiple sites
  • R10.8A1 – R10.8A3 Flank/suprapubic tenderness (side-specific)
  • R10.8A9 Flank tenderness, unspecified
  • R10.A0 – R10.A3 Flank pain (side-specific and unspecified)

Contusions (S-Codes)

Deleted: S30.1XXA/D/S Contusion of abdominal wall.

Added:

  • S30.11XA – S30.11XS Abdominal wall contusion (initial, subsequent, sequela)
  • S30.12XA – S30.12XS Groin contusion
  • S30.13XA – S30.13XS Flank (latus) region contusion

Musculoskeletal & Other Relevant Codes

  • M21.159 Varus deformity, unspecified hip
  • M61.129 Myositis ossificans progressive, unspecified upper arm
  • R39.851 – R39.859 Costovertebral (angle) tenderness (side-specific)

Neurology (Multiple Sclerosis – G35)

Deleted: G35 Multiple sclerosis.

Added:

  • G35.A Relapsing-remitting MS
  • G35.B0 – B2 Primary progressive MS (unspecified, active, non-active)
  • G35.C0 – C2 Secondary progressive MS (unspecified, active, non-active)
  • G35.D Multiple sclerosis, unspecified

Practical Impact for DCs

  • Coding precision is increasing: Many previously single codes (e.g., pelvic pain, contusion of abdominal wall, multiple sclerosis) now have laterality, site-specificity, and disease activity requirements.
  • Claims risk: Using a deleted or outdated code after Oct. 1 will result in claim denial.
  • Best practice: Update your EHR, superbills, and macros now to ensure correct code selection.

Diagnosing Radiculopathies Through History & Observation
Diagnosing Radiculopathies Through History & Observation

MRI is currently the gold standard for identifying radicular pathology, but unfortunately, it requires preauthorization, which isn’t easy to obtain. Physical tests are what most practitioners depend on – despite the marginal reliability of the tests. The information in this article brings history and observation to the forefront of radicular diagnostics. Each factor listed can significantly increase the clinician’s ability to diagnose radiculopathies.

Multiple-Procedure Claim Reductions?
Multiple-Procedure Claim Reductions?

With some plans – and it starts with Medicare (CMS) – there is a payment protocol called the multiple-procedure payment reduction (MPPR). This protocol means that if a health care provider performs multiple procedures during a single patient encounter, Medicare (and many commercial insurers) typically will pay “full price” for only the highest-valued procedure. The subsequent procedures will be reduced, as there is overlap.

From Sciatica to Brain Tumor: A Life-Saving Diagnosis

A 42-year-old male former patient arrives at your chiropractic office with excruciating low back pain that travels all the way down his right leg to his foot. A spinal surgeon previously recommended surgery to correct an MRI-confirmed disc herniation (sequestration) at L5, but the patient chose conservative chiropractic care. Although conservative treatment is effective for many lumbar disc herniations, the warning signs in this case call for escalation.
