ICD code V26.29XS – Nontraffic motorcycle crash with nonmotor vehicle, sequela

Key takeaways

V26.29XS is a valid, billable ICD-10-CM code, but only as a secondary external cause code.

It fits an unspecified rider of a motorcycle, other than an electric bicycle, who collided with a nonmotor vehicle away from a public highway.

The 7th character S means sequela: the injury has healed, and today’s visit is for a residual condition it caused.

The residual condition, such as post-traumatic arthritis, is always coded first, and Y92, Y93 and Y99 codes stay off sequela claims.

Pabau’s claims management software pre-fills the claim from the patient record and checks required fields before you send it.

ICD-10 code V26.29XS covers a nontraffic motorcycle sequela

ICD-10 code V26.29XS is the ICD-10-CM code for an unspecified rider of other motorcycle injured in collision with other nonmotor vehicle in nontraffic accident, sequela. It sits in Chapter 20, External causes of morbidity, of the CDC/NCHS ICD-10-CM classification. That chapter holds the transport accident codes, V00-V99.

In plain terms, the patient was on a motorcycle that collided with an animal-drawn vehicle, a ridden animal or a streetcar. The crash happened away from a public highway, and the chart doesn’t say whether they were driving. The injury has since healed, and today’s visit is for what it left behind.

The code is valid and billable, but only as a secondary code. It never takes the first-listed position on a claim.

Each character in V26.29XS answers one question

Read the code left to right and it tells the payer who was hurt, how, and when. Knowing the structure heads off the two slips that cause the most rework: a missing placeholder X and the wrong rider role.

The placeholder X is mandatory. ICD-10-CM needs seven characters for this code, and nothing occupies the 6th position, so X holds the slot. V26.29S, with six characters, is structurally invalid and gets rejected.

The 7th character S marks an injury that has healed

The 7th character tells the payer which phase of care the visit belongs to. The three options don’t overlap, so only one can be right for a given visit.

Under the ICD-10-CM Official Guidelines, S marks a condition that remains after the injury itself has healed. Timing alone never decides it. Take a patient still in physical therapy for a broken collarbone from the crash. That visit takes D. Two years later, a visit for post-traumatic shoulder arthritis takes S.

Code the residual condition first, then V26.29XS

Sequela coding follows a fixed order. The residual condition comes first, because it’s the reason for the visit. The original injury code, with 7th character S, comes next, and V26.29XS follows as the external cause.

Here’s how that looks in practice. A patient returns two years after a crash on a private farm road and now has post-traumatic arthritis in the right shoulder. The chart never says who was driving. You’d lead with the arthritis code, add the healed shoulder injury with S, then report V26.29XS.

• Step 1: Confirm from the physician’s note that the acute collision injury has healed.
• Step 2: Code the residual condition, for example M19.111 for post-traumatic osteoarthritis, right shoulder.
• Step 3: Add the code for the original injury with 7th character S.
• Step 4: Assign V26.29XS as the external cause code.
• Step 5: Leave off place (Y92), activity (Y93) and status (Y99) codes, which belong to the initial encounter only.

V26.29XS never stands alone on a claim. If the residual condition’s own code is what’s holding you up, our ICD-10-CM code guides cover the conditions that usually lead these claims.

V26 covers collisions with nonmotor vehicles, away from traffic

Category V26 covers motorcycle riders injured in a collision with other nonmotor vehicle. In ICD-10-CM, that means an animal-drawn vehicle, an animal being ridden, or a streetcar. A collision with a pedal cycle belongs in V21 instead.

“Other motorcycle” means a rider of any motorcycle except an electric (assisted) bicycle, which takes 5th character 1, as in V26.21. The 4th character .2 makes this a nontraffic accident, one that happened entirely away from a public highway. The traffic versions use .4 for a driver, .5 for a passenger and .9 for an unspecified rider.

The grid below maps all six sequela codes in this corner of the category.

Residual conditions that bring these patients back for sequela visits include:

• Post-traumatic osteoarthritis of a joint injured in the collision
• Fracture nonunion or malunion at a collision-related fracture site
• Chronic pain syndrome attributable to the collision
• Peripheral nerve injury sequela, such as neuropathy from limb trauma
• Scarring or contracture from soft-tissue injuries sustained in the collision

Know what V26 includes and excludes before you code

The category boundaries decide whether V26.29XS fits at all. A collision with the wrong kind of vehicle moves the claim to a different category entirely.

What V26 includes

Collisions between a motorcycle and an animal-drawn vehicle, an animal being ridden, or a streetcar fall within scope.

What V26 excludes

• Motor vehicle collisions: A crash with a motorized vehicle codes to V22-V25. Those cover two- or three-wheeled motor vehicles, cars, pick-ups and vans, heavy transport vehicles and buses, and trains.
• Pedal cycle collisions: A crash with a bicycle codes to V21.
• Noncollision crashes: A skid or fall with no collision moves to category V28, as in V28.19XS for a passenger.

Code the sequela condition first

For every sequela encounter, the residual condition leads. Chapter 20 codes are never first-listed, so V26.29XS always follows it.

Neighboring codes that get mistaken for V26.29XS

Rider role trips coders up because charts often skip it. If the chart confirms the patient was operating the motorcycle, use the driver code. If it confirms a pillion rider, use the passenger code. If the note is silent or ambiguous, V26.29XS is correct.

Electric bicycles sit on a separate branch, with 5th character 1. V26.41XD shows that branch for a driver in a traffic accident, at a follow-up visit.

V26.29XS needs a companion code, and nothing from Y92 to Y99

V26.29XS always travels with the diagnosis code for the residual condition. The rest of the claim depends on what you leave off as much as what you add.

• Residual condition code (required): Always code the residual condition first. This is the first-listed diagnosis, and V26.29XS follows it.
• Original injury code with S: The injury that caused the sequela takes 7th character S and sits after the residual condition.
• No Y92, Y93 or Y99 codes: Place of occurrence (Y92), activity (Y93) and external cause status (Y99) are reported once, at the initial encounter. They aren’t added to V26.29XS sequela encounters.

So a status code such as Y99.8, which flags leisure activity, belongs on the first visit after the crash. It doesn’t come back on the sequela claim, even if the chart repeats it.

The note needs four facts before you assign V26.29XS

If any of these is missing, query the provider before you submit. Sound medical billing compliance means coders never infer external cause details the record doesn’t state.

• The collision type: The note must say the patient was a motorcycle rider who collided with a nonmotor vehicle. A general “motor vehicle accident” isn’t enough for V26.
• Where it happened: The crash must have happened away from a public highway. If it happened on a public road, the traffic code V26.99XS applies instead.
• A causal link to today’s complaint: The physician must document that today’s condition resulted from the prior collision. A note such as “post-traumatic arthritis of the right knee from the crash” does that. Without that link, the residual condition is coded without an external cause.
• Rider role, or its absence: If the chart is silent on driver or passenger, V26.29XS fits. If it says “driver” or “operator,” use V26.09XS instead. Never assume rider role.

How payers treat V26.29XS on a claim

V26.29XS is a valid secondary code, but no national rule requires external cause codes. The ICD-10-CM guidelines leave reporting to state mandates and payer policy, and encourage it voluntarily everywhere else.

Medicare: CMS doesn’t require external cause codes for Medicare fee-for-service claims. Some Medicare Advantage plans and state Medicaid programs do ask for them on injury claims, especially where auto insurance may pay first. Check the plan’s billing manual before you treat the code as optional.

State mandates: Many states require external cause codes in hospital claims data, and some state Medicaid programs extend that to professional claims. Your state Medicaid billing manual has the current rule.

How the claim moves: On a CMS-1500, list the residual condition in box 21 first, then the injury code with S, then V26.29XS. Point each service line in box 24E to the residual condition, never to the external cause code.

Five mistakes that get V26.29XS claims denied

Motorcycle sequela claims tend to fail in the same few ways. Catching these before submission is cheaper than working them back through denial management after the payer responds.

• V26.29XS listed first, or alone: External cause codes are supplementary. A claim that leads with V26.29XS, or carries no residual condition code, fails edits straight away.
• Missing placeholder X: V26.29S is structurally invalid. A clearinghouse usually rejects it, and one that lets it through leaves the payer to deny it.
• S during active treatment: If the injury is still being treated, A or D applies. Using S too early misstates the clinical picture and can prompt requests for records.
• The wrong rider role: If the note says “patient was driving the motorcycle,” reporting V26.29XS is a specificity error. Use V26.09XS, and query the provider when the note is ambiguous.
• The wrong road status: A crash on a public road is a traffic accident. The unspecified rider code there is V26.99XS, not V26.29XS.

Before you submit

A clean claim for a sequela visit passes every one of these checks before it leaves the practice:

• The residual condition is first, the injury code with S is next, and V26.29XS follows them.
• The code has seven characters, with X in the 6th position.
• The injury has healed, and the note links today’s condition to the crash.
• The crash happened away from a public highway.
• The rider role matches the note, or the note is silent on it.
• No Y92, Y93 or Y99 codes appear on the claim.

How Pabau takes the retyping out of sequela claims

A sequela claim often starts from a note written long after the crash. Someone has to pull the residual condition, the healed injury and the external cause into one claim by hand. A slip in any of the three sends it back.

Pabau, the practice management platform we build, handles this through simpler claims management. It pre-fills the claim form from the patient record, so the ICD-10-CM codes already on the problem list land in the diagnosis slots. A built-in code library lets you look up V26 siblings without leaving the claim.

Before the Send button unlocks, Pabau checks that required claim fields are complete, such as membership numbers and authorization codes.

US practices submit through the Claim.MD clearinghouse integration, with eligibility checks, claim-status tracking and remittance posting in the same place. Your team spends less time retyping codes and more time with the patients coming back for care.

Build sequela claims from the patient record

Pabau pre-fills claim forms from the patient record, checks required fields before you send, and tracks each claim through Claim.MD. Fewer claims come back for missing details.

Conclusion

V26.29XS rewards a careful read of the note more than coding speed. Before you use it, confirm three things: the injury has healed, the crash happened away from a public highway, and the rider role is unknown. If any one of them fails, a sibling code fits better.

The trade-off is time. A provider query might hold the claim for a day, while a denied sequela claim costs far more in rework. When the note is thin, ask before you submit.
