What this actually is
You bring your specialist expertise to AI evaluation. The shape of the work varies but the pattern is the same: review outputs, rate quality, write prompts, flag errors. The platform title (Clinical Documentation Integrity (CDI) Specialist) reflects the rate band and the expertise required, not the day-to-day work.

Original posting from Mercor
To qualify you must work regularly in a professional inpatient CDI or coding role - hospital CDI (specialist or leadership), inpatient DRG coding/auditing, or clinical-documentation denial management - with 2+ years of experience under ICD-10-CM/PCS and the MS-DRG system.
Clinical documentation knowledge we require
Coding & the pre-bill cycle
- ICD-10-CM/PCS assignment, POA reporting, and the inpatient DRG assignment and reimbursement cycle
- Concurrent and retrospective (pre-bill) review, DRG reconciliation (working vs. final), and tie-out of coded diagnoses to source documentation in the record
Judgment & evaluation
- CC/MCC impact and DRG movement; when a diagnosis does or doesn't change the DRG, severity of illness, or risk of mortality
- Code changes and their coupled effects (principal-diagnosis sequencing, DRG shift, dollar and quality impact)
Clinical standards & criteria
- Applying published clinical criteria to the record - AKI staging (KDIGO), sepsis, respiratory failure, malnutrition, CKD staging - and UHDDS reporting rules
- Distinguishing a clinically supported diagnosis from an unsupported or templated/copy-forward one; clinical validation
Query & compliance discipline
- AHIMA/ACDIS-compliant, non-leading query construction; when a query is required versus when specificity is already provider-documented
- The bright line: indicators justify a query, never a code - never add, delete, or change a provider-documented diagnosis without a provider response
Documentation & evidence
- Query vs. CDI-review vs. note standards, hold/pending mechanics, review-ready completeness
- Evidence provenance: a lab value, document, baseline, or DRG figure is only valid if it is actually in the record and produced by the grouper, not asserted
Tools
- Comfort in professional CAC/CDI software - computer-assisted coding and CDI workflow platforms (e.g., Dolbey Fusion, 3M 360 Encompass, Nuance/Optum360), DRG groupers, and EHR systems (e.g., Epic)
What you'll do
- Review AI-agent attempts at realistic CDI/coding tasks and judge whether each disposition is correct and adequately supported by the record
- Confirm work is actually completed and recorded - codes changed, queries sent (not left in draft), holds placed, DRG recomputed, notes and CDI reviews filed - not just described
- Catch fabricated or overstated work: cited labs, documents, or prior encounters that don't exist, a claimed provider response that never came, DRG or dollar figures not produced by the grouper
- Judge completeness and whether the right action was applied to the right chart - code fix vs. query vs. clinical-validation query vs. leave-alone - and require verify-before-finalize
- Write clear, specific agree/disagree rationales on each attempt
Requirements
- 2+ years of professional experience in one or more of: inpatient hospital CDI (specialist or leadership), inpatient DRG coding/auditing, or clinical-documentation denial management
- Current or recent hands-on work under ICD-10-CM/PCS and MS-DRGs
- Reflexive professional judgment; can spot an unsupported diagnosis, a leading query, a missed CC/MCC, or a rubber-stamped account on sight
- CCDS, CDIP, CCS, RHIA/RHIT, or RN with CDI experience (or equivalent); hospital, coding, or HIM background
- Comfort working inside CAC/CDI software and reading the full clinical record - H&Ps, consults, progress notes, discharge summaries, labs, and flowsheets
