Healthcare AI Use Cases & Costs
| Task | Tokens (in/out) | Claude Haiku 4.5 | Claude Sonnet 4.6 | Claude Opus 4.6 |
|---|---|---|---|---|
| Clinical note from transcript (SOAP format) | 1,000 in / 500 out | $0.003500 | $0.010500 | $0.017500 |
| Discharge summary (from chart notes) | 3,000 in / 800 out | $0.007000 | $0.021000 | $0.035000 |
| Prior authorization letter | 2,000 in / 1,000 out | $0.007000 | $0.021000 | $0.035000 |
| ICD-10 / CPT coding suggestion | 800 in / 100 out | $0.001300 | $0.003900 | $0.006500 |
| Patient message response (portal) | 500 in / 200 out | $0.001500 | $0.004500 | $0.007500 |
| Medication reconciliation review | 1,500 in / 300 out | $0.003000 | $0.009000 | $0.015000 |
| Care plan summary (for patient) | 2,000 in / 600 out | $0.005000 | $0.015000 | $0.025000 |
| Clinical trial eligibility screening | 3,000 in / 200 out | $0.004000 | $0.012000 | $0.020000 |
Healthcare AI is predominantly input-heavy (patient records, charts, transcripts) with moderate output. Haiku is cost-effective for high-volume routine tasks; Sonnet/Opus for complex clinical reasoning.
Monthly AI Cost by Healthcare Organization Size
| Organization | Monthly AI activity | AI cost (Haiku) | AI cost (Sonnet) |
|---|---|---|---|
| Solo practice (1 physician) | 20 notes/day, 200 patient messages/mo, 50 coding suggestions | $24/mo | $72/mo |
| Small clinic (5 physicians) | 100 notes/day, 1K patient messages, 250 prior auth letters | $113/mo | $340/mo |
| Hospital system (100 physicians) | 2,000 notes/day, 20K messages, 5K prior auths, 5K coding | $2,205/mo | $6,615/mo |
| Health tech product (B2B) | 1M notes/month processed | $3,500/mo | $10,500/mo |
Clinical Documentation ROI
AI clinical documentation (ambient note-taking from visit audio) is one of the highest-ROI healthcare AI use cases:
- A physician sees 20 patients/day, spending ~2 minutes post-visit on notes = 40 minutes/day on documentation
- AI reduces documentation time by 50–70% → saves 20–28 minutes/day per physician
- At $300/hour physician cost: 25 minutes saved × $5/min = $125/day saved per physician
- AI note cost (Haiku): 20 notes × $0.0035 = $0.07/day
- ROI: 1,785×
HIPAA Compliance Considerations
| Provider | BAA available? | Deployment option | Notes |
|---|---|---|---|
| Anthropic API | Yes (enterprise plans) | Direct API | BAA available for qualifying enterprise customers |
| AWS Bedrock (Claude) | Yes (via AWS BAA) | Managed service | AWS is a covered entity; standard AWS BAA covers Bedrock |
| Azure OpenAI | Yes (via Azure BAA) | Managed service | HIPAA-eligible service under Microsoft's Azure BAA |
| OpenAI API (direct) | Enterprise only | Direct API | BAA requires enterprise agreement; not available on pay-as-you-go |
| Google Vertex AI (Gemini) | Yes (via Google Cloud) | Managed service | Google Cloud BAA covers Vertex AI; PHI processing supported |
For PHI (Protected Health Information): always use a BAA-covered deployment path. Cloud managed services (Bedrock, Azure, Vertex) are the easiest path to HIPAA compliance.
Which Model for Healthcare AI
- ICD-10/CPT coding, triage classification: Claude Haiku 4.5 — structured classification tasks; cache specialty-specific coding guidelines
- Clinical note generation, patient messages: Claude Haiku 4.5 — excellent format following; cache note templates (SOAP, H&P) as system prompt prefix
- Prior authorization letters, discharge summaries: Claude Sonnet 4.6 — quality matters for payer acceptance and clinical accuracy
- Complex differential diagnosis, specialist consult notes: Claude Sonnet 4.6 or Opus 4.6 — high-stakes reasoning; accuracy is paramount
- De-identification of PHI: Claude Haiku 4.5 — use for bulk PHI removal before passing to non-BAA systems; structured output
