ICD code V91.02XD – Burn due to fishing boat on fire

Key takeaways

V91.02XD is a billable ICD-10-CM external cause code for burns from a fishing boat fire, reported at a subsequent (follow-up) encounter.

The 7th character D separates follow-up visits from the initial encounter (A) and sequela (S). Keeping XA after the first active-treatment visit is the most common denial trigger.

V91.02XD is never the first-listed diagnosis. A burn T-code for the degree and body site must precede it on every claim.

Practice management software like Pabau checks that payer details, such as membership numbers and authorization codes, are in place before each claim is sent.

ICD-10 code V91.02XD: Code at a glance

ICD-10 code V91.02XD is the billable external cause code for a burn caused by a fishing boat on fire, reported at a subsequent encounter. It sits in Chapter 20 of ICD-10-CM and always follows a burn T-code on the claim. Per the CDC/NCHS ICD-10-CM web tool, the code is valid and billable for the current fiscal year. The table below sums up the facts to confirm before you submit a claim.

What V91.02XD covers: Official code description

V91.02XD covers a patient burned when a fishing boat caught fire, seen at a follow-up visit after initial active treatment. The code captures both the vessel type and the encounter phase. A fishing boat is coded apart from a merchant ship, a passenger ship, or a sailboat.

Three elements must all be true for V91.02XD to apply:

• Burn injury mechanism: The burn resulted directly from a fishing boat that was on fire, not from another watercraft type or from drowning or submersion.
• Vessel type: A fishing boat specifically. Merchant ships, passenger ships, and other powered watercraft each have their own V91.0 code.
• Encounter phase: The patient is presenting for ongoing wound care, scar management, or a related follow-up, not for the first active treatment of the burn.

V91.02XD is an external cause code. It describes how and where the injury happened, while the accompanying T-code records the burn itself by degree (first, second, third) and body site. That T-code is listed first on the claim.

Understanding the 7th character in ICD-10 code V91.02XD

The 7th character is mandatory for all V91.02 codes and changes what the code reports. The CMS ICD-10-CM official guidelines allow three options. Choosing the wrong one after the first visit is the top coding error in this code family. The character reflects the phase of care, not the severity of the injury.

The diagram below follows one fishing boat burn through all three phases and shows the claim order at a follow-up visit.

When to use V91.02XD vs V91.02XA

V91.02XA applies at the first encounter where a provider actively treats the burn. V91.02XD applies at every visit after that, for as long as the patient receives routine care for the same injury.

The practical test is documentation-based: If the clinical note reflects active initial evaluation and management of a new burn, XA is correct. If the note shows wound checks, dressing changes, scar monitoring, or medication refills for an established injury, XD is correct. A single injury can generate many XD claims across weeks or months of follow-up. It generates only one XA claim.

V91.02XD as an external cause code: How to use it correctly

V91.02XD is classified under Chapter 20 of ICD-10-CM (External Causes of Morbidity), so it can never stand alone as a diagnosis. Section I.C.20 of the ICD-10-CM Official Guidelines governs every external cause code. It states that codes from this chapter are never the principal or first-listed diagnosis. The injury code describes what was injured, and the external cause code describes how and why.

The same rule holds for burns from other mechanisms. X05.XXXD reports a nightwear burn at a subsequent encounter, and it also follows the T-code on the claim.

Correct sequencing on a claim containing V91.02XD follows this order:

1. First-listed (principal) diagnosis: The burn T-code reflecting degree and body site, for example T23.201D for a second-degree burn of the right hand.
2. Additional diagnosis: V91.02XD as the external cause code describing the injury mechanism.
3. Any other relevant codes: Additional codes for complications, concurrent conditions, or place of occurrence.

Required primary codes to pair with V91.02XD

The T-code depends on the burn degree and the specific body site involved. The table below lists the burn T-code categories most often paired with V91.02XD on a subsequent-encounter claim. Each T-code must also carry the 7th character D to match the encounter phase. AAPC’s ICD-10-CM code lookup helps you confirm the correct T-code subdivision by body site and degree.

Excludes notes and coding restrictions

Category V91 and its V91.0 subcategory carry exclusion notes that decide whether V91.02XD is the right code. Reading them correctly prevents both over-coding and under-coding on complex trauma cases.

• Excludes2, drowning and submersion (V90.-): This note covers drowning and submersion due to accident to watercraft. An Excludes2 note means the condition is not part of V91, but a patient can have both. A burn patient who was also submerged gets V91.02XD plus a separate V90 code. A patient who jumped from the burning fishing boat falls under V90.22, and a late-effect visit for that submersion is coded V90.22XS.
• Excludes1, military watercraft: A military watercraft accident in military or war operations is excluded from V91 and falls under Y36 or Y37. A civilian water transport accident involving a military watercraft goes to V94.81- instead.
• Excludes1 at V91.0, localized fire (V93.-): A burn from a localized fire or explosion on board, with no accident to the watercraft, goes to V93.-.
• V91.02XD does not capture: Burns sustained on land after leaving a fishing boat, or burns from a fire on any other type of vessel.

Neighboring codes: The V91.0 burn subcategory

V91.02XD sits in V91.0, the subcategory for burns due to a watercraft on fire. The table below lists every V91.0 code at the subsequent encounter, so you can confirm the documented watercraft matches the code.

When documentation says “commercial fishing vessel” rather than “merchant ship,” V91.02XD remains appropriate. When the vessel type is ambiguous, V91.09XD (unspecified watercraft) is the fallback. Never assume the vessel type from context alone.

Payer requirements and documentation checklist

Medicare, Medicaid, and most commercial payers do not require prior authorization for external cause codes. They do expect documentation that supports the code’s clinical logic, and five points carry most of the weight.

• Circumstance of injury documented: The clinical note must state how the burn occurred. “Patient sustained burns when fishing vessel caught fire on [date]” is sufficient. A vague note such as “burn injury” with no mechanism will not support V91.02XD.
• Prior encounter records accessible: Payers may ask for evidence that an initial encounter (XA) was billed before the subsequent encounters (XD). Keep prior visit records easy to retrieve.
• Burn T-code sequenced first: V91.02XD must appear as an additional code, never in the first diagnosis position on the CMS-1500 or 837P.
• 7th character matches the encounter: Confirm the T-code and the V91.02 code both carry the D suffix for the same visit. Mismatched 7th characters between the two are a common edit-reject trigger.
• Place of service accurate: Outpatient wound care and inpatient burn unit visits carry different place-of-service (POS) codes. Confirm the POS matches where treatment was delivered.

Common claim denial reasons for V91.02XD

Watercraft burn claims are a niche category, but their denials are predictable. Most trace back to one of the five causes below. Tracking the denial codes behind rejections on V91 claims over a quarter shows which cause drives them at your practice.

• V91.02XD in the first-listed position: External cause codes cannot anchor a claim. Payers reject any claim where a Chapter 20 code sits in position 1. The fix is simple, but it needs a workflow check before submission.
• 7th character not switched from XA to XD: Continuing to use V91.02XA on follow-up visits is the most common error in this code family. Once initial active treatment is documented, every subsequent visit carries XD.
• Missing or mismatched T-code: V91.02XD sent without a burn T-code triggers an edit reject. So does pairing it with a T-code that carries a different 7th character, such as T23.201A.
• Thin documentation of the injury circumstance: Claims that reach audit without a note describing the fishing boat fire are open to medical necessity denials. Confirm the documentation before submitting, not after a denial arrives.
• Wrong vessel subcategory: Submitting V91.02XD when the note says “recreational motorboat” rather than “fishing boat” is a specificity error. Use V91.03XD for other powered watercraft when the fishing boat descriptor is absent.

ICD-9-CM crosswalk for V91.02XD

V91.02XD has no direct one-to-one ICD-9-CM equivalent. The ICD-9-CM E-code system covered external causes of injury, but it lacked vessel-type detail and encounter-phase 7th characters. Per ResDAC’s ICD coding resources for Medicare files, General Equivalence Mappings (GEMs) for external cause codes are approximate. They should not be used for prospective coding, so the crosswalk below is for historical reference and payer audit response only.

If a payer audit references legacy ICD-9 data, point out that the CMS GEMs documentation flags this conversion as approximate.

How Pabau keeps V91.02XD claims complete before submission

A follow-up burn claim can pass every coding check and still bounce because a membership number or authorization code is missing. That rejection lands weeks later, after several more XD visits have gone out the same way.

Practice management software like Pabau includes claims management with validation checks. They run in the background each time you send a claim and confirm the payer details insurers need are in place. Sequencing the burn T-code first and choosing the 7th character stay with your coder.

In the US, Pabau connects to the Claim.MD clearinghouse. From there you submit claims electronically, run real-time eligibility checks, track claim status, and post electronic remittance advice (ERA). Each claim shows as pending, submitted, processing, paid, or error, so a rejected V91.02XD claim is easy to spot and resubmit.

Streamline your burn injury billing with Pabau

Pabau checks membership numbers and authorization codes before each claim is sent. It then tracks every V91.02XD claim through Claim.MD from submission to payment.

Conclusion

V91.02XD claims fail for a short, predictable list of reasons. Build three checks into every follow-up visit: The burn T-code goes first, both codes carry D, and the note names the fishing boat fire.

The trade-off is a few seconds of review per claim against a denial that can repeat across weeks of wound care visits. Fix the EHR template once, and the same error stops copying forward.
