Quick answer: A HCPCS code for a finger splint is chosen from the device descriptor, not from the product name. In the 2021 DME MAC article on finger orthoses, four codes describe a splint worn on the finger’s PIP and DIP joints: L3927 (static, prefabricated off-the-shelf), L3925 (dynamic, prefabricated off-the-shelf), L3933 (static, custom fabricated) and L3935 (dynamic, custom fabricated).
This page describes products and general use; it is not medical advice. It also does not state coverage, payment or fees. Anyone coding a claim should confirm the current code with their DME MAC or the PDAC.
Who looks this up: clinic and supplier staff who code or order orthoses, buyers comparing product listings, and students learning how HCPCS Level II names devices.
What a finger splint HCPCS code covers
HCPCS Level II is, in CMS’s words, a coding system “used primarily to identify products, supplies, and services not included in the CPT codes”, for example durable medical equipment, prosthetics, orthotics and supplies. CMS maintains the Level II codes and decides on additions, revisions and deletions (CMS HCPCS page, checked 2026-11-01). A finger splint code therefore names the device. The act of applying a splint is a procedure and is a different kind of code (see the common mistakes below).
For general background on what a splint is and how finger splints differ physically, see what a splint is and finger splint types. For the sibling coding question on wrist devices, see HCPCS code for a wrist brace.
Finger splint codes at a glance
The table follows the Noridian JA DME and CGS Jurisdiction B DME MAC article “Correct Coding of Finger, Hand, Hand-Finger and Wrist-Hand-Finger Braces (Orthoses)” (originally 10/28/21, revised 11/18/21). Descriptors are shortened here; the article carries the full wording.
| Code | Descriptor (shortened) | Static or dynamic | Fabrication |
|---|---|---|---|
| L3927 | Finger orthosis, PIP/DIP, without joint/spring, extension/flexion (e.g., static or ring type), may include soft interface material | Static | Prefabricated, off-the-shelf |
| L3925 | Finger orthosis, PIP/DIP, nontorsion joint/spring, extension/flexion, may include soft interface material | Dynamic (rubber band or spring) | Prefabricated, off-the-shelf |
| L3933 | Finger orthosis, without joints, may include soft interface, includes fitting and adjustment | Static | Custom fabricated |
| L3935 | Finger orthosis, nontorsion joint, may include soft interface, includes fitting and adjustment | Dynamic | Custom fabricated |
Static vs dynamic: which descriptor applies
The descriptors separate the two types by one feature. A static finger orthosis is “without joint/spring”: it holds the finger and does not move. A dynamic one has a nontorsion joint or spring that controls flexion and/or extension, which the article describes as rubber bands or springs. So the question to ask of a product is whether it contains a joint or spring element, not whether the listing calls it a splint. The concept is explained in static vs dynamic splints.
Prefabricated vs custom fabricated
The same article separates the pairs by wording in the descriptor. L3925 and L3927 say “prefabricated, off-the-shelf”. L3933 and L3935 say “custom fabricated” and “includes fitting and adjustment”. A mass-produced finger splint taken from stock therefore sits in the L3925/L3927 pair, while a device made for one individual sits in the L3933/L3935 pair.
| Static | Dynamic | |
|---|---|---|
| Prefabricated, off-the-shelf | L3927 | L3925 |
| Custom fabricated | L3933 | L3935 |
Hand-finger codes that are not finger splint codes
The article lists a separate “hand finger orthosis” group. L3924 is “hand finger orthosis, without joints, may include soft interface, straps, prefabricated, off-the-shelf”. L3923 uses the same opening wording, and the article describes it as a prefabricated item trimmed, bent, molded, assembled or otherwise customized to fit a specific patient. These describe devices that include the hand, so they are not the answer to a splint that covers only the finger joints. Some third-party listing sites label L3925 as a wrist-hand-finger orthosis; the DME MAC article classes it as a finger orthosis.
No add-on codes
For each of these codes the article states: “This is a complete device and no add-on codes may be billed for this orthosis.” Soft interface material, straps and closures are part of the device descriptor, so they are not separate items under these codes.
Finger splint HCPCS code: how to verify before ordering
- Write down the product’s name and manufacturer, and whether it is stocked (prefabricated) or made for one person.
- Check whether the product has a joint or spring element (dynamic) or none (static).
- Match those two answers to the 2×2 table above, then read the full descriptor in the current DME MAC article.
- Ask the supplier which code they intend to use and have them show how the product matches the descriptor.
- Confirm with your DME MAC, or with the PDAC (the Pricing, Data Analysis and Coding contractor), because the article above is dated 2021 and codes and articles are revised. CMS publishes HCPCS quarterly update files, so a code’s status should be checked in the current file.
Common mistakes
- Coding the procedure instead of the device. Codes for applying a splint are a separate family; the L-codes above name the product.
- Choosing a hand-finger code for a finger-only splint. L3923 and L3924 belong to the hand-finger group.
- Billing straps or padding separately. The article says no add-on codes may be billed for these orthoses.
- Treating a listing site as the authority. Use the DME MAC article and the current CMS file.
- Mixing up static and dynamic. The L3927 descriptor gives “static or ring type” as examples of a device without joint or spring; only a device with a nontorsion joint or spring is dynamic.
FAQ
What is the HCPCS code for a finger splint?
There is no single code. The 2021 DME MAC article lists L3927 (static, prefabricated), L3925 (dynamic, prefabricated), L3933 (static, custom fabricated) and L3935 (dynamic, custom fabricated).
Is there a finger splint HCPCS code for a simple off-the-shelf static splint?
The descriptor that fits a prefabricated device with no joint or spring is L3927. Confirm it with your DME MAC or PDAC before ordering.
Does the code include the straps and padding?
Yes. The article says these are complete devices and no add-on codes may be billed.
Does this page say Medicare will pay for a finger splint?
No. It covers code descriptors only, not coverage, payment or fees.
