+# Mission Control — Bouwplan Diagnose Module
+
+**Projectnaam:** Diagnose Module - Mini EPD
+**Versie:** v1.1
+**Datum:** 11-12-2024
+**Auteur:** Colin Lit
+
+---
+
+## 1. Doel en context
+
+**Doel:** De bestaande diagnose-functionaliteit uitbreiden naar een volwaardige module met doorzoekbare ICD-10 classificatie, verbeterde UX en hoofd-/nevendiagnose ondersteuning.
+
+**Toelichting:**
+De huidige implementatie (`diagnosis-manager.tsx`) is een basic formulier met handmatige code-invoer. Dit bouwplan beschrijft de upgrade naar:
+- Doorzoekbare **ICD-10 codelijst** (~50 GGZ-codes, client-side filtering)
+- **Modal-based invoer** (in plaats van inline formulier)
+- **Diagnose cards** met visuele status badges
+- Hoofd-/nevendiagnose markering
+- DSM-5 referentieveld (vrije tekst)
+
+**Referentiedocumenten:**
+- PRD: `docs/specs/diagnose/prd-diagnose-module-v1.md` (v1.1)
+- FO: `docs/specs/diagnose/fo-diagnose-module-v1.md` (v1.1)
+- TO: `docs/specs/diagnose/to-diagnose-module-v1.md` (v1.0)
+
+---
+
+## 2. Uitgangspunten
+
+### 2.1 Technische Stack
+- **Frontend:** Next.js 14 App Router + Tailwind CSS + shadcn/ui
+- **Database:** Supabase PostgreSQL (bestaande `conditions` tabel)
+- **UI Components:** shadcn/ui Dialog, Command (cmdk), Badge, Card
+- **Form Handling:** react-hook-form + zod
+- **Icons:** Lucide React
+
+### 2.2 Projectkaders
+- **Scope:** Prototype voor demo
+- **Data:** Statische ICD-10 JSON (~50 codes), geen API call
+- **Licentie:** ICD-10 = publiek domein (WHO). DSM-5 vereist licentie.
+- **AI:** Optioneel / post-MVP
+
+### 2.3 Programmeer Uitgangspunten
+
+**Code Quality Principles:**
+- **DRY:** Herbruikbare ICD-10 zoekcomponent, diagnose types
+- **KISS:** Client-side filtering (geen server call voor 50 codes)
+- **SOC:** Modal logica gescheiden van lijst weergave
+- **YAGNI:** Geen AI-suggesties in v1, geen patiënt-breed overzicht
+
+**Development Practices:**
+- Bestaande `conditions` tabel gebruiken (geen schema wijzigingen)
+- Server actions in bestaande `actions.ts` uitbreiden
+- shadcn/ui Command component voor autocomplete

+# 🧩 Functioneel Ontwerp (FO) – Diagnose Module
+
+**Projectnaam:** Diagnose Module - Mini EPD
+**Versie:** v1.1
+**Datum:** 11-12-2024
+**Auteur:** Colin Lit
+
+---
+
+## 1. Doel en relatie met het PRD
+
+🎯 **Doel van dit document:**
+Het Functioneel Ontwerp beschrijft **hoe** de diagnosemodule in de praktijk werkt voor GGZ-professionals. Dit document vertaalt de requirements uit het PRD naar concrete schermen, acties en interacties.
+
+📘 **Toelichting aan de lezer:**
+Dit FO beschrijft de diagnose-functionaliteit voor het prototype met **ICD-10 classificatie** (publiek domein) als basis en optionele DSM-5 referentie. De focus ligt op een eenvoudige, werkende flow voor demo-doeleinden.
+
+**Relatie met PRD:**
+Dit FO implementeert de requirements uit `prd-diagnose-module-v1.md` (v1.1), specifiek:
+- ICD-10 classificatie browser (PRD 3.1)
+- Diagnose registratie met DSM-5 referentieveld (PRD 3.2)
+- AI-ondersteuning (PRD 3.3) — optioneel voor prototype
+
+> **Licentie-opmerking:** DSM-5 vereist licentie. Dit prototype gebruikt ICD-10 (publiek domein).
+
+---
+
+## 2. Overzicht van de belangrijkste onderdelen
+
+1. **Diagnose Tab** (binnen Intake) — Hoofdlocatie voor diagnose-registratie
+2. **ICD-10 Code Zoeken** — Autocomplete met GGZ-subset (~50 codes)
+3. **Diagnose Invoer Modal** — Formulier voor nieuwe/bewerken diagnose
+4. **Diagnose Detail Card** — Weergave per geregistreerde diagnose
+5. *(Optioneel)* **AI Diagnose Assistent** — Suggesties op basis van intake
+
+---
+
+## 3. Userstories (Prototype)
+
+| ID | Rol | Doel / Actie | Verwachte waarde | Prioriteit |

+# 📄 Product Requirements Document (PRD) – Diagnose Module
+
+**Projectnaam:** Diagnose Module - Mini EPD
+**Versie:** v1.1
+**Datum:** 11-12-2024
+**Auteur:** Colin Lit
+
+---
+
+## 1. Doelstelling
+
+🎯 **Doel:** Een diagnosemodule bouwen voor het prototype die psychologen in staat stelt diagnoses gestructureerd vast te leggen met ICD-10 codes (publiek domein) en DSM-5 referenties.
+
+📘 **Toelichting:**
+De huidige diagnose-functionaliteit is minimaal: een simpel formulier met handmatige code-invoer. Deze MVP breidt dit uit naar een werkende module met:
+- Doorzoekbare **ICD-10 classificatie** (publiek domein, geen licentie nodig)
+- DSM-5 equivalent als referentieveld (vrije tekst)
+- Meervoudige diagnoses per intake (hoofd- en nevendiagnoses)
+- Status tracking (actief, in remissie, opgelost)
+- AI-ondersteuning voor diagnose-suggesties
+
+**Type:** Prototype voor demo en validatie.
+
+> **Licentie-opmerking:** DSM-5 classificaties vallen onder licentie van Boom uitgevers. Voor productie is een licentie vereist. Dit prototype gebruikt ICD-10 (WHO, publiek domein) als primaire classificatie.
+
+---
+
+## 2. Doelgroep
+
+🎯 **Primaire doelgroep:**
+- **Psychologen / Regiebehandelaren:** Stellen diagnoses en hebben behoefte aan efficiënte classificatie met onderbouwing.
+- **Psychiaters:** Valideren diagnoses, voegen specialistische classificaties toe.
+
+📘 **Secundaire doelgroep:**
+- **Product Owners & Managers:** Demo van AI-potentieel in diagnostisch proces.
+- **Developers:** Referentie-implementatie voor medische classificatiesystemen.
+
+**Persona's:**
+> - **Marieke (GZ-psycholoog):** Wil snel DSM-5 codes kunnen vinden zonder handboek. Wil zien welke diagnoses passen bij de intake-bevindingen.
+> - **Peter (Psychiater):** Wil comorbiditeit vastleggen met hoofd/nevendiagnose structuur. Heeft behoefte aan differentiaaldiagnostiek.
+
+---
+
+## 3. Kernfunctionaliteiten (MVP-scope)
+
+### 3.1 ICD-10 Classificatie Browser
+1. **Doorzoekbare codelijst:** Zoeken op code (F32.1) of beschrijving ("depressieve episode").
+2. **Categorie navigatie:** Hiërarchische structuur (Hoofdgroep → Subgroep → Specifieke diagnose).
+3. **Snelkeuze:** Veelvoorkomende GGZ-diagnoses (top 30).
+
+### 3.2 Diagnose Registratie
+4. **ICD-10 code:** Primaire classificatie (verplicht).
+5. **DSM-5 referentie:** Optioneel vrije-tekst veld voor DSM-5 equivalent.
+6. **Meervoudige diagnoses:** Hoofd- en nevendiagnoses (primair/secundair markering).
+7. **Ernst classificatie:** Licht / Matig / Ernstig.
+8. **Status tracking:** Actief / In remissie / Opgelost / Ingevoerd-in-fout.
+9. **Notities veld:** Onderbouwing en klinische redenering.
+
+### 3.3 AI-ondersteuning
+10. **Diagnose-suggesties:** Op basis van intake-notities en anamnese (ICD-10 codes).
+11. **Differentiaal-helper:** Toon vergelijkbare diagnoses met onderscheidende kenmerken.
+
+### 3.4 Integratie
+12. **Behandelplan-koppeling:** Diagnoses beschikbaar als input voor behandelplan.
+13. **Overdracht-integratie:** Actieve diagnoses in overdrachtsamenvatting.
+
+### *(Stretch / Post-prototype)*
+- Volledige DSM-5 integratie (na licentie-afsluiting)
+- Diagnose-overzicht patiënt-breed
+- Versiebeheer diagnoses
+
+---
+
+## 4. Gebruikersflows (MVP-flows)
+
+### Flow 1: Diagnose toevoegen via zoeken
+```
+1. Psycholoog opent Diagnose tab binnen intake
+2. Klikt [+ Nieuwe diagnose]
+3. Zoekt op "depressie" of "F32"
+4. Selecteert "F32.1 - Depressieve stoornis, matig"
+5. Vult ernst in (dropdown: matig)
+6. Markeert als hoofddiagnose (toggle)
+7. Voegt optionele notitie toe
+8. Klikt [Opslaan]
+```
+
+### Flow 2: AI-suggestie gebruiken
+```
+1. Psycholoog opent Diagnose tab
+2. Klikt [AI › Analyseer intake]
+3. Systeem analyseert intake-notities + anamnese
+4. Toont 2-4 diagnose-suggesties met confidence score
+5. Per suggestie: onderbouwing uit intake-tekst (citaten)
+6. Psycholoog selecteert relevante suggestie(s)
+7. Past aan indien nodig → [Opslaan]
+```
+
+### Flow 3: Differentiaaldiagnose bekijken
+```
+1. Bij geselecteerde diagnose (bijv. F41.1 GAD)
+2. Klikt [Differentiaal bekijken]
+3. Toont gerelateerde diagnoses:
+   - F41.0 Paniekstoornis
+   - F43.1 PTSS
+   - F32.1 Depressie met angstkenmerken
+4. Per alternatief: kernverschillen uitgelicht
+5. Psycholoog bevestigt of past diagnose aan
+```
+
+### Flow 4: Diagnose-overzicht raadplegen
+```
+1. Psycholoog opent Patiënt dossier
+2. Navigeert naar Diagnoses sectie (L2 menu)
+3. Ziet overzicht alle diagnoses (actief + historisch)
+4. Filter op status: Actief / In remissie / Alle
+5. Klik op diagnose → details + gekoppelde intake
+```
+
+---
+
+## 5. Niet in Scope (Prototype)
+
+| Feature | Reden |
+|---------|-------|
+| Volledige DSM-5 classificatie | Licentie vereist (Boom uitgevers) |
+| DSM-5 criteria/checklists | Licentiegebonden content |
+| Multi-disciplinaire validatie workflow | Complexiteit, geen meerwaarde voor demo |
+| Automatische DBC/ZPM-koppeling | Vereist externe integraties |
+| Medicatie-diagnose interacties | Buiten scope |
+| ICD-11 ondersteuning | Nog niet gangbaar in NL GGZ |
+
+---
+
+## 6. Succescriteria
+
+| Criterium | Meetbaar doel |
+|-----------|---------------|
+| Code-zoekfunctie | < 3 klikken van zoeken naar selectie |
+| AI-suggesties | Relevante suggestie in top-3 bij 80% van intakes |
+| Differentiaal | Toon minimaal 2 relevante alternatieven |
+| Demo-flow | Volledige diagnose-registratie in < 60 seconden |
+| Data-integriteit | Diagnoses correct gekoppeld aan intake + patiënt |
+| Overdracht | Actieve diagnoses automatisch in AI-samenvatting |
+
+---
+
+## 7. Risico's & Mitigatie
+
+| Risico | Impact | Mitigatie |
+|--------|--------|-----------|
+| AI-suggesties onjuist/onvolledig | Hoog | Duidelijke disclaimer, suggesties als hulpmiddel niet als diagnose |
+| ICD-10 minder bekend bij GGZ | Laag | Codes zijn identiek aan DSM-5, alleen beschrijvingen verschillen |
+| Complexe classificatie UI | Middel | Focus op top 30 GGZ-diagnoses, rest via zoeken |
+| Performance bij grote codelijst | Laag | Client-side filtering + debounce |
+
+---
+
+## 8. Roadmap / Vervolg (Post-Prototype)
+
+### Fase 2: DSM-5 Licentie
+- Licentie afsluiten met Boom uitgevers
+- DSM-5 beschrijvingen en criteria toevoegen
+- Volledige DSM-5/ICD-10 mapping
+
+### Fase 3: Verdieping
+- Diagnose-overzicht patiënt-breed (over intakes)

+
+## 10. Technische Uitgangspunten
+
+### Database (bestaande `conditions` tabel)
+```typescript
+// Huidige velden (FHIR-inspired)
+- code_code: string        // ICD-10 code (bijv. "F32.1")
+- code_display: string     // ICD-10 beschrijving
+- code_system: string      // 'ICD-10' (primair voor prototype)
+- clinical_status: enum    // active | remission | resolved
+- verification_status: enum // provisional | confirmed | entered-in-error
+- severity_code: string
+- severity_display: string
+- onset_datetime: timestamp
+- recorded_date: timestamp
+- note: text
+- patient_id: uuid
+- encounter_id: uuid       // Gekoppelde intake
+```
+
+### Nieuwe velden (Prototype)
+```typescript
+- is_primary: boolean      // Hoofd- vs nevendiagnose
+- dsm5_reference: text     // Optioneel: DSM-5 equivalent (vrije tekst)
+```
+
+### Statische data (JSON)
+```typescript
+// lib/data/icd10-ggz-codes.json
+// Top ~50 GGZ-relevante ICD-10 codes met Nederlandse beschrijvingen
+[
+  { "code": "F32.0", "display": "Lichte depressieve episode", "category": "Depressie" },
+  { "code": "F32.1", "display": "Matige depressieve episode", "category": "Depressie" },
+  ...
+]
+```
+
+### API Endpoints
+```
+GET  /api/diagnose/codes?q={search}  // Zoek ICD-10 codes (client-side fallback)
+POST /api/diagnose/suggest           // AI suggesties (optioneel)
+```
+
+---
+
+## 11. ICD-10 GGZ Code Subset (Prototype)
+
+Focus op meest voorkomende GGZ-diagnoses (~50 codes). De ICD-10 codes zijn identiek aan DSM-5, alleen de beschrijvingen komen uit de WHO-classificatie (publiek domein).
+
+| Categorie | ICD-10 Codes | Voorbeelden |
+|-----------|--------------|-------------|
+| **Depressieve stoornissen** | F32.x, F33.x | Depressieve episode (licht/matig/ernstig) |
+| **Angststoornissen** | F40.x, F41.x | Sociale fobie, GAD, Paniekstoornis |
+| **Trauma/stress** | F43.x | PTSS, Aanpassingsstoornis |
+| **OCD** | F42.x | Obsessief-compulsieve stoornis |
+| **Persoonlijkheid** | F60.x | Borderline, Antisociaal, Vermijdend |
+| **Bipolair** | F31.x | Bipolaire stoornis |
+| **ADHD** | F90.x | Aandachtstekortstoornis |
+| **Autisme** | F84.x | Autismespectrumstoornis |
+| **Eetstoornissen** | F50.x | Anorexia, Boulimia |
+
+> **Opmerking:** Voor productie kunnen de volledige DSM-5 beschrijvingen worden toegevoegd na licentie-afsluiting.
+
+---
+
+## 12. AI Prompt Strategie (Optioneel)
+
+### Diagnose-suggestie prompt
+```
+Je bent een klinisch ondersteuningssysteem voor GGZ-professionals.
+
+CONTEXT:
+- Intake notities: {intakeContent}
+- Anamnese: {anamneseContent}
+
+OPDRACHT:
+Analyseer de informatie en geef maximaal 3 diagnose-suggesties met ICD-10 codes.
+
+Per suggestie:
+1. ICD-10 code en beschrijving
+2. Onderbouwing met citaten uit de intake
+3. Ernst-indicatie (licht/matig/ernstig)
+
+BELANGRIJK:
+- Dit zijn SUGGESTIES ter ondersteuning, geen diagnoses
+- De clinicus neemt altijd de eindbeslissing
+- Gebruik alleen ICD-10 codes uit de GGZ-subset (F-codes)
+```
+
+> **Prototype scope:** AI-suggesties zijn optioneel voor de eerste versie. Focus eerst op de handmatige invoer-flow.

+## 3. Dependency Analyse
+
+### Bestaande dependencies (reeds aanwezig)
+
+| Dependency | Versie | Gebruik |
+|------------|--------|---------|
+| `@radix-ui/react-dialog` | ^1.1.15 | Modal voor diagnose invoer |
+| `@radix-ui/react-select` | ^2.2.6 | Dropdowns (ernst, status) |
+| `lucide-react` | ^0.553.0 | Icons (Search, Plus, Trash) |
+| `date-fns` | ^4.1.0 | Datum formatting |
+| `zod` | ^4.1.12 | Input validatie |
+| `react-hook-form` | ^7.66.1 | Form handling |
+| `@hookform/resolvers` | ^5.2.2 | Zod resolver |
+
+### Nieuwe dependency (toe te voegen)
+
+| Dependency | Versie | Gebruik | Alternatief |
+|------------|--------|---------|-------------|
+| `cmdk` | ^1.0.0 | Autocomplete/Combobox voor ICD-10 zoeken | Custom met Radix Popover |
+
+**Aanbeveling:** Voeg `cmdk` toe voor de autocomplete functionaliteit. Dit is de standaard voor shadcn/ui Command component.
+
+```bash
+pnpm add cmdk
+```
+
+**Alternatief:** Bouw custom autocomplete met bestaande `@radix-ui/react-popover` + input. Minder features maar geen extra dependency.
+
+---
+
+## 4. Database Schema
+
+### Bestaande `conditions` tabel (geen wijzigingen nodig)
+
+De huidige `conditions` tabel is al FHIR-compliant en bevat alle benodigde velden:
+
+```sql
+-- Bestaande tabel (lib/supabase/database.types.ts:291-369)
+conditions (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  patient_id UUID NOT NULL REFERENCES patients(id),
+  encounter_id UUID REFERENCES intakes(id),  -- Gekoppelde intake
+
+  -- ICD-10/DSM-5 classificatie
+  code_code TEXT NOT NULL,                    -- "F32.1"
+  code_display TEXT NOT NULL,                 -- "Matige depressieve episode"
+  code_system TEXT DEFAULT 'ICD-10',          -- "ICD-10" of "DSM-5"
+
+  -- Status (FHIR enums)
+  clinical_status condition_clinical_status DEFAULT 'active',
+    -- active | recurrence | relapse | inactive | remission | resolved
+  verification_status condition_verification_status DEFAULT 'confirmed',
+    -- unconfirmed | provisional | differential | confirmed | refuted | entered-in-error
+
+  -- Ernst
+  severity_code TEXT,                         -- "mild" | "moderate" | "severe"
+  severity_display TEXT,                      -- "Licht" | "Matig" | "Ernstig"
+
+  -- Timing
+  onset_datetime TIMESTAMPTZ,
+  recorded_date DATE DEFAULT CURRENT_DATE,
+
+  -- Extra

+  category TEXT DEFAULT 'encounter-diagnosis',
+
+  -- Metadata
+  created_at TIMESTAMPTZ DEFAULT NOW(),
+  updated_at TIMESTAMPTZ DEFAULT NOW()
+);
+```
+
+### Optionele schema-uitbreiding (later)
+
+Voor de toekomst kunnen deze velden worden toegevoegd via migratie:
+
+```sql
+-- Optioneel: nieuwe velden voor uitgebreide functionaliteit
+ALTER TABLE conditions ADD COLUMN IF NOT EXISTS is_primary BOOLEAN DEFAULT false;
+ALTER TABLE conditions ADD COLUMN IF NOT EXISTS dsm5_reference TEXT;

+
+## 9. Implementatie Stappenplan
+
+### Fase 1: Data & Types (1-2 uur)
+1. Creëer `lib/data/icd10-ggz-codes.json` met ~50 codes
+2. Creëer `lib/types/icd10.ts` met TypeScript types
+3. Creëer `lib/schemas/diagnosis.ts` met Zod schema
+
+### Fase 2: Componenten (3-4 uur)
+4. Installeer `cmdk` dependency
+5. Creëer `ICD10Combobox` component
+6. Creëer `DiagnosisModal` component
+7. Creëer `DiagnosisCard` component
+
+### Fase 3: Integratie (2 uur)
+8. Refactor `diagnosis-manager.tsx` naar nieuwe componenten
+9. Update server actions (ICD-10, update functie)
+10. Test flows: toevoegen, bewerken, verwijderen
+
+### Fase 4: Polish (1 uur)
+11. Lege staten en error handling
+12. Loading states
+13. Toast feedback
+
+---
+
+## 10. Testen
+
+### Handmatige test scenario's
+
+| # | Scenario | Verwacht resultaat |
+|---|----------|-------------------|
+| 1 | Zoek "depressie" | Toont F32.x codes |
+| 2 | Zoek "F41" | Toont angststoornissen |
+| 3 | Selecteer code | Vult beschrijving automatisch |
+| 4 | Opslaan zonder code | Validatiefout |
+| 5 | Bewerk bestaande | Modal met voorgevulde waarden |
+| 6 | Verwijder diagnose | Bevestiging + toast |
+| 7 | Leeg veld | Toont top 5 snelkeuze |
+
+### Build verificatie
+
+```bash
+pnpm build  # Moet slagen zonder type errors
+```
+
+---
+
+## 11. Risico's & Mitigatie
+
+| Risico | Impact | Mitigatie |
+|--------|--------|-----------|
+| cmdk bundle size | Laag | ~10KB gzipped, acceptabel |
+| ICD-10 codes incompleet | Laag | Start met 50, uitbreiden op aanvraag |
+| Performance filtering | Laag | 50 codes is instant client-side |
+| Bestaande data breekt | Middel | Backward compatible, DSM-5 data blijft werken |

+# Diagnose Module - Implementatieplan
+
+## Overzicht
+Implementatie van een verbeterde diagnosemodule voor het Mini-EPD prototype met:
+- ICD-10 classificatie (publiek domein, geen licentie nodig)
+- Autocomplete zoekfunctionaliteit
+- Consistente UX/UI volgens bestaande EPD patterns
+
+## Documentatie Status ✅
+- [x] PRD v1.1 - `docs/specs/diagnose/prd-diagnose-module-v1.md`

+- [x] UX/UI Specificaties (zie hieronder)
+
+---
+
+## UX/UI Design Beslissingen
+
+### Kleurenschema (conform ux-stylesheet.md)
+| Element | Kleur | Hex |
