Hand & Wrist diagnosis codes, from the official FY2026 files
Hand and wrist coding mixes nerve codes (carpal tunnel is a G code, not an M code), tendon families (trigger finger by digit, de Quervain), elbow enthesopathies, and two enormous injury families — distal radius fractures (S52.5) and wrist/finger sprains (S63).
Every code below is billable in FY2026. Descriptions are reproduced verbatim from the official ICD-10-CM release (NCHS/CMS — public domain). 116 codes shown on this page.

Reading these codes correctly
- Laterality is inside the code. Many families end in 1 (right), 2 (left), and sometimes 3 (bilateral) or 9 (unspecified). Payers increasingly deny “unspecified side” when a sided code exists — capture right vs. left on the very first phone call.
- Injury (S) codes need a 7th character. The tables below show initial encounter (A) codes. The same code exists with D (subsequent encounter) for routine follow-up care and S (sequela) for late effects. A follow-up visit billed with an “A” code is a mismatch.
- Codes update every October 1. These tables are from the official FY2026 ICD-10-CM release (public domain, NCHS/CMS). Verify against the current year's files before billing.
Where the phone call fits
Every code on this page starts as a sentence a patient says on the phone. ClinicFlow's scheduling agent captures the complaint, the side, and the duration on the first call and writes it into the EMR — so intake, scheduling, and coding tell the same story.

Frequently asked questions
What is the ICD-10 code for carpal tunnel syndrome?
G56.01 for the right upper limb, G56.02 for the left, and G56.03 for bilateral. It's a mononeuropathy (G) code, which makes it easy to miss when searching the M chapter.
How is trigger finger coded?
The M65.3- family branches by digit and side — for example M65.321 (trigger finger, right middle finger). De Quervain's tenosynovitis is the neighboring M65.4.
What is the code for a distal radius fracture?
The S52.5- family, branching by fracture pattern (including Colles and Smith patterns) and side, with the injury 7th character. The tables here show initial-encounter closed-fracture (A) codes.
