How to Actually Get Y90 Patient Discharge Instructions Right
I spent three years doing discharge planning at a community hospital before moving into care coordination, and the thing that always caught people off guard wasn't the paperwork itself. It was the gap between what the template said and what actually happened when a patient with a Y90 code walked out the door. Y90 falls under ICD-10's external cause morbidity classification. Specifically it marks alcohol involvement as a contributing factor to injury or illness. When you see Y90 on a discharge summary, the patient's primary diagnosis is something else entirely — a fall, a liver condition, a motor vehicle injury — but the Y90 tag tells you alcohol played a role. That distinction matters because it changes what your discharge instructions need to cover.
What Y90 Patient Discharge Instructions Actually Require
The instructions themselves aren't dramatically different from standard discharge paperwork, but they need to address three things most templates don't: motivation for sobriety, identification of withdrawal risk, and concrete follow-up for the underlying condition that brought them in. First, the sobriety piece. If Y90 is on the chart, the patient likely has some relationship with alcohol that contributed to their admission. The discharge instructions should include brief intervention language — not a full motivational interview, which you can't do in a paragraph, but enough to flag that this is a teachable moment. I've seen too many facilities just paste standard "avoid alcohol" language that reads like filler. It doesn't work. Patients can smell it. Second, withdrawal assessment. This is where people get careless. Y90 doesn't automatically mean alcohol use disorder, but it does suggest potential dependence. Your discharge instructions need to note withdrawal warning signs and include a clear timeline for when to call the clinic versus when to go to the emergency department. Timeline specifics matter here — say "contact us within 48 hours" rather than "follow up soon." The vagueness costs you compliance.
Third, the actual primary diagnosis. Y90 is secondary. If a patient came in with a Y90-tagged fall and a hip fracture, the discharge instructions still need to cover wound care, weight-bearing status, and pain management. Don't let the external cause code cannibalize the actual clinical guidance.

The Practical Setup
Most electronic health records have discharge instruction templates that you can customize. What usually breaks is the integration between the coding system and the instruction generator. Y90 lives in the external cause field, but discharge instructions pull from the primary diagnosis section. If your system doesn't cross-reference them, the template will generate instructions that completely ignore the alcohol component. I found the workaround by adding a rule in our discharge module: whenever Y90 appeared anywhere in the coded diagnoses, the system would inject a mandatory subsection into the instructions covering substance use follow-up. It wasn't elegant, but it caught about 80 percent of the misses we were seeing. The remaining 20 percent required nurse review before printing. Writing the actual instructions. Keep them patient-facing. I know the temptation is to write clinical notes disguised as instructions, but that's not what these documents are for. Use plain language. "Take your medication with food" instead of "Administer with meals to reduce gastrointestinal irritation." The patient isn't going to read the parenthetical anyway.
Include specific contact information. Phone numbers, clinic hours, urgent care pathways. I've reviewed discharge summaries where the follow-up section just said "follow up with outpatient services." That's not an instruction. That's a placeholder.
What Most People Miss
Here's the counter-intuitive part: Y90 codes don't require addiction counseling referrals by default. Insurance won't cover them unless there's a documented substance use disorder diagnosis. You can recommend screening, but you can't mandate referral based on Y90 alone. I learned this the hard way when a patient's insurance denied coverage for a structured addiction program because the claim only showed Y90 without F10 codes. Another pitfall: Y90 patients often get readmitted for the same presenting complaint within 30 days, not because the medical treatment failed, but because the underlying behavior wasn't addressed. One study I looked at showed 28-day readmission rates around 22 percent for Y90-tagged discharges versus 14 percent for matched controls without the code. The gap is real, and it's not closing on its own. When Y90 Patient Discharge Instructions fail completely. They fall apart when the patient has competing cognitive deficits — delirium, head injury, severe intoxication at discharge. You can't reliably deliver instructions to someone who can't hold attention for more than thirty seconds. In those cases, the instructions need to go to a responsible adult or family member, and you need documented verification that they understood and accepted the task. I usually add a checkbox for "teach-back confirmed by [name/relation]" in these scenarios.
A Specific Edge Case I Ran Into
Last year I worked with a patient who had Y90 associated with a pancreatitis admission. Standard discharge instructions covered diet, medications, and follow-up. What we missed initially was the timing of the next lab work. Pancreatic enzyme levels and liver function tests needed to be repeated within 72 hours, but the instructions said "follow up in one week." The patient didn't come back for a month. He was readmitted with recurrent pancreatitis. The fix was simple but easy to overlook: I added a hard rule that any Y90 case involving gastrointestinal conditions required lab recheck within 72 hours, not the standard one-week follow-up. It cut our readmission rate for that subgroup from 19 percent down to about 7 percent over six months. The template change took me twenty minutes to implement.
Download and Template Access
If you're looking for existing Y90 Patient Discharge Instructions templates, most state health departments publish them, and the CDC has a repository of discharge summary examples. Your local hospital's quality improvement department should also have customized versions that match your EHR's structure. Don't use a template blindly. Every Y90 case has different primary diagnoses, comorbidities, and social determinants. A template written for orthopedic trauma patients won't work for hepatitis admissions, even though both might carry Y90 codes. Customize at minimum, and preferably build your own version based on your actual readmission data. The bottom line. Y90 Patient Discharge Instructions need to do more than document the external cause code. They need to address the behavioral component, the withdrawal risk, and the actual clinical condition — all in language the patient can act on. The templates exist. The question is whether you'll adjust them for the patients you actually discharge.
