"...long, long, time ago, I can still remember, when..."
It might have been 2002, and I was at an NHCAA conference in San Diego in June, perhaps. NHCAA stands for Nation Health Care Anti-fraud Association, I was there with another co-worker.
This is the annual convention and draws people from all types of fraud departments: State Insurance, Federal Law Enforcement, Commercial insurers, and from companies like mine Blue Cross Blue Shield plans across the nation. I think it runs 4 days.
Birds of a feather flock together, and after one day or so of presentations, a group of us from us went to one of the malls, Fashion Mall, I think.
It was accessible by the trolley, which is part of San Diego's mass transit system. There was trolley stop right behind the hotel,
San Diego the, and maybe still, uses an honor system fro paying the fare. You buy a ticket and show it, if asked to an enforcement individual, who might be on the trolley, or asking you for the ticket as you get off. But there not always there.
There are no turnstiles like the N.Y.C. subway. The trolley runs at ground level, powered by pantograph wires overhead. The ride is as smooth as a baby's bottom, because I think the trolley's wheels are rubber.
The station stops are almost sidewalks. You can walk across the tracks to the other side with no chance of any danger.
Being the New Yorker, I am I marveled at the system, especially the honor system for fare collection. I felt proud of myself when I was confronted at a bus stop for my ticket by uniformed fare enforcers. They almost seemed surprised I had one. I wasn't playing the wise guy, conniving New Yorker to beat the fare.
So, here we are at the Fashion Mall, and I can't get over the trolley and the ability to walk across, or along the tracks.
Being who I am, I envisioned getting killed by a trolley. Further, I wondered how they would code the accident using the ICD-10 manual, International Classification of Diseases: Death by trolley? Death by trolley going uptown? Downtown? Electric trolley? Diesel powered?
I kept this patter up as we went to and from the Fashion Mall. "Death by trolley." A woman from the Louisiana Blue Cross Blue Shield thought this was quite funny. They don't come across many New Yorkers whose accent make then sound like a gangster, thinking out loud on how to code an unusual death. We can he a handful. We stayed in touch. Somewhat.
Don't laugh, the ICD-10 manual is thick with codes to uses for all kinds of diseases. Toward the back are a series of alphanumeric codes that attempt to assign a code to an event causing death that is not a medical death. Maybe something like a car accident.
But the codes can be quite granular, and an event might need several codes to capture the cause of death, as we will see.
The world runs on statistics, and having a uniform coding system for cause of death allows for research into causes. Medical reasons are understandable. Other types of events that might cause death are varied as well: violence, suicide, accidents by all sorts of conveyances, crime, there is quite a list.
There was quite a bit of teeth gnashing on how to code the deaths from the World Trade Center, the Pentagon, and Shanksville, Pennsylvania. Hijacked 767s not using a runway to land causing death was a coding challenge. Did NYC have a sudden surge in homicides? Oh boy.
I immediately thought of the investigator from Louisiana (who is now a manager of the unit) when I was putting the posting together about the assistant night club manager who was crushed to death by a piano that was accidently hydraulically lifting itself to the ceiling while he was on top of a stripper making whoopee. The assistant manger was crushed to death, and the screaming stripper was found the next morning with bruises, but otherwise not physically hurt. A janitor discovered the scene the following morning when he came in to start cleaning.
Being stuck for hours under a corpse on top of you while you're on a piano pressed against he ceiling, had to leave some mental damage. Eventually, more coding.
The woman from Louisiana was still working for the Blue Cross Blue Shield plan, which made me wonder how young was she when I was going on about "death by trolley?" No matter.
We connected via LinkedIn. I linked her to the blog posting about the assistant night club manager killed in a very unusual manner, and asked her if she'd use the ICD-10 book and code the event for me. The book is expensive and I have no need to have one.
She admitted she was not a coder (there are certified coders as a profession) but took a stab with T14.8, crushed, severe, unspecified site. Certainly fits.
I also asked her if she could also code the Central Park carriage accident where a young man fell out of the carriage attempting to help his mother when the carriage was tipped over because the horse felt a charge of stray electricity in its hoof from the pavement, and ran off. The young man hit his head on the pavement and died. Lots of news there. Louisiana passed on that one, but was a bit astonished that I still brought up "death by trolley" after all thee years.
The coding of unusual deaths still niggled in my brain. It got me thinking. How would they code that? Why not ask AI? Well, ChatGPT reveals how much can go into capturing all the elements of a death precipitated by a horse feeling a stray electrical charge in its hoof and running off while tipping the carriage over, causing a passenger to fall out and fatally crack their skull on the pavement. You got to admit, a lot went into having a very bad day.
ChatGPT:
"The best fit is:
"V80.02XA — Occupant of animal-drawn vehicle injured by fall from or being thrown from animal-drawn vehicle in non-collision accident, initial encounter.
"That category specifically includes an overturning animal-drawn vehicle without a collision, which is essentially what happened when the horse bolted and tipped the carriage.
"For a death certificate/mortality coding, however, the coding works somewhat differently. The CDC says that transportation accidents are classified primarily according to the victim's mode of transportation, and the underlying-cause code is generally selected at the three-character level rather than using the full clinical 7-character injury code.
"So the mortality coding would likely center on:
V80 — Animal-rider or occupant of animal-drawn vehicle injured in transport accident
with the circumstances further described in the record.
"But there is another important part
The actual cause of death would be the fatal head injury—not the horse's electrical sensation. For example, if the medical examiner determined that the passenger died from a traumatic skull fracture and brain injury, the medical cause would be something along the lines of:
Fatal traumatic brain injury due to skull fracture from fall onto pavement
and the V80 code supplies the external circumstances.
"The electrical charge that startled the horse is an additional causal circumstance. ICD-10 mortality coding is designed to capture the chain of events, and the CDC specifically notes that when transportation is involved, the transportation accident is coded as an external cause.
"So, in plain English, your hypothetical could be represented as:
Horse receives stray electrical shock → horse bolts → carriage overturns → passenger is thrown/falls from carriage → strikes head on pavement → fatal skull/brain injury.
"ICD-10-CM external cause: V80.02XA (for the injury encounter)
Underlying mortality classification: V80 (animal-drawn vehicle transport accident)
"One wrinkle: because you specifically said “death precipitated by a horse feeling a stray electrical charge in its hoof,” there may be an argument for separately coding the electrical event. If you're asking this because you're trying to reconstruct how an actual historical death would have been coded, I can dig into the ICD-10 Index and show exactly how the electrical shock → runaway horse → overturned carriage → skull fracture chain would be coded on a death certificate.
