Every year, the healthcare industry adjusts to a new round of ICD-10-CM code updates, the essential diagnostic codes used for insurance claims, reporting, and documentation. For acupuncture and integrative medicine practices, staying on top of these updates isn’t just about compliance, it’s about ensuring your claims get paid and your documentation reflects modern medical accuracy.

The ICD-10-CM changes 2026, effective October 1, 2025, brings notable refinements that focus on specificity and precision. While there are no direct changes to the most common acupuncture pain codes, there are several updates that may still impact your claims, particularly for abdominal pain, tenderness, trauma, and multiple sclerosis as a comorbidity.

Let’s break down what’s changing, what’s new, and what you should do right now to stay compliant and avoid denials.

ICD-10-CM 2026 at a Glance

Here’s the big picture for this year’s release:

• Total ICD-10-CM Codes: 74,179

• Additions: 487

• Deletions: 28

• Revisions: 38

Effective Date: October 1, 2025
Important: Always code based on the date of service, not claim submission date.

• Services before Oct. 1, 2025 → Use 2025 ICD-10 codes
• Services on/after Oct. 1, 2025 → Use 2026 ICD-10 codes

Failing to make this distinction will result in claim denials or delayed payments

Key Changes in ICD-10 Codes for Acupuncture Clinics

While pain management remains at the heart of acupuncture billing, new ICD-10 updates for 2026 are adding more granularity, especially in cases involving abdominal pain, contusions, or neurological disorders like multiple sclerosis.

Here’s what you need to know.

1. Pain & Tenderness (R-Codes)

Deleted Codes

• R10.2 – Pelvic and perineal pain

New & Revised Codes

What This Means for Acupuncturists

For many acupuncture patients presenting with pelvic or flank pain, the new ICD-10 codes for acupuncture 2026 now require you to specify the side and exact site of pain.

Your SOAP note should capture:

• Laterality (right, left, bilateral)
• Type of pain (pelvic, suprapubic, flank)

Tip: Update your EHR templates so providers can select the correct site during documentation, this ensures cleaner claims and fewer rejections.

2. Contusions (S-Codes)

Deleted

• S30.1XXA/D/S – Contusion of abdominal wall

Added Codes

Impact on Your Practice

If you treat post-trauma or injury cases, you’ll need to use the updated codes that reflect:

• The specific region (abdominal wall, groin, flank)
• The encounter type (initial, subsequent, or sequela)

🧾 Example:

If a patient returns for follow-up after a flank contusion, use S30.13XD (subsequent encounter).

3. Neurology: Multiple Sclerosis (G35 Series)

Deleted

• G35 – Multiple sclerosis

New Codes

 Relevance for Acupuncturists

If you treat patients with multiple sclerosis as a comorbidity (for fatigue, neuropathy, or mobility issues), you’ll now need to specify MS type and disease activity.

This precision supports medical necessity and reimbursement consistency.

 Avoid These Common Coding Mistakes

12 new codes added in 2026 for hearing device services: including training/support for patients using personal devices connected to hearing devices, assessing psychosocial factors, verifying device performance.

What to watch: If audiology or hearing‐aid support is part of your practice (or you refer patients), check whether these new codes affect your services or partnerships.

Steps to Stay Compliant Before October 1

1. Update your EHR / billing software to load all new ICD-10-CM codes.

2. Audit your most-used codes, replace deleted or revised ones.

3. Revise SOAP note templates for pain and tenderness documentation.

4. Train your front-desk and billing staff to recognize deleted codes.

5. Verify claims by date of service before submission.

Example: Corrected SOAP Note

Before (2025)

Diagnosis: Pelvic pain, unspecified.
Code: R10.2

After (2026)

Diagnosis: Right pelvic and suprapubic pain, chronic.
Codes: R10.21 (Pelvic/perineal pain, right side), R10.24 (Suprapubic pain)

Improved documentation = higher claim acceptance.

New/Removed CPT Codes

Acupuncturists treat a variety of conditions, requiring specific ICD-10 codes for accurate reimbursement. From musculoskeletal disorders to neurological conditions, understanding the most relevant acupuncture billing codes is essential for seamless claims processing and revenue cycle management.

Here are a few concrete examples to illustrate the changes (you’ll want to look up the full list in your CPT 2026 codebook or data file).

• New: Codes for short-duration remote monitoring (2-15 days within 30-day period), added in 2026. 
• New: Codes for AI-augmented services (e.g., coronary plaque assessment, perivascular fat analysis). 
• New: Hearing device codes (12 codes) for training/support and device performance. 
• Removed: 84 codes deleted in 2026 (in total), practice must check which ones affect them. 
• Modified: 46 codes revised in 2026, e.g., descriptor edits, bundling changes.

Practical Impact on Acupuncture Billing and Claims

The 2026 ICD-10 updates reflect a continued move toward greater diagnostic specificity, which directly affects how acupuncture claims are billed and reimbursed.

Here’s what these updates mean for your day-to-day operations:

1. Claims using deleted codes after Oct. 1, 2025, will be denied.
Insurance payers will automatically reject claims that contain codes removed or replaced in the 2026 ICD-10 update. For example, using the deleted code R10.2 (Pelvic and perineal pain) instead of its new, more specific replacements (R10.20–R10.23) will cause immediate claim rejection. These denials delay payments and can affect cash flow, so it’s essential to verify that your system automatically replaces outdated codes.

2. Laterality and encounter type are now mandatory for accuracy.
Many pain-related and trauma codes now require you to document whether the pain is on the right, left, or both sides, and to indicate the encounter type (A = initial visit, D = follow-up, S = sequela). Incomplete documentation may result in down-coded or denied claims, especially with injury-related conditions (S-codes).

3. EHR systems and superbills must be updated before October 1, 2025.
Before the effective date, review your electronic health record (EHR) and printed superbills to ensure all ICD-10 code lists reflect the 2026 revisions. This prevents staff from accidentally selecting old codes and ensures accurate claim submission from day one of the transition.

4. Documentation templates should support side- and site-specific detail.
The new R10-series pain codes (for abdominal, flank, and pelvic pain) require additional specificity in documentation. SOAP note templates should include fields for “pain location,” “side of body,” and “encounter type.” This small adjustment ensures your clinical documentation automatically supports the correct ICD-10 coding.

5. Improved accuracy reduces claim rework and speeds up payment cycles.
When your documentation matches ICD-10 requirements, claim scrubbing tools identify fewer errors, reducing rework and payer inquiries. Accurate ICD-10 coding also helps justify the medical necessity of acupuncture treatments for chronic or recurrent pain, supporting consistent reimbursement.

The 2026 ICD-10 changes emphasize coding clarity and precision. Acupuncturists who update their documentation workflows, billing templates, and EHR settings early will minimize disruptions and maintain steady revenue as the new codes take effect.

Preparing Your Practice for Acupuncture Diagnosis Codes 2026

a. Review common ICD 10 codes for acupuncture that you use and identify those affected by the update.

b. Update your EHR system, SOAP note templates, and superbills.

c. Train your staff on new R10, S30, and G35 series codes.

d. Verify that your billing software automatically updates ICD 10 code for acupuncture

e. Test sample claims before the effective date.
