Mapping from ICD-10-CM: what to do meanwhile

Prepare without a map

Without an official map, prepare with what WHO's guidance already gives you.

What NCVHS lists as US interests

NCVHS lists what the US still has to work out: alternative code set mapping including SNOMED CT, post-coordination standards, semantic equivalence and technical implementation in EHRs, and the financial impact of reimbursement based on ICD-11 versus ICD-10-CM.

• Mapping · Other sets · Alternative code set mapping, including with SNOMED CT.
• Technical · EHR · Post-coordination standards, semantic equivalence and technical implementation in EHRs.
• Impact · Money, risk · The financial impact of reimbursement based on ICD-11 versus ICD-10-CM, and risk adjustment precision.

Four practical steps

Our advice, built on WHO's guidance. One: know the gap, because WHO's maps are for WHO ICD-10 and ICD-10-CM is a modification. Two: use dual coding studies. Three: plan to run old and new in parallel for at least eighteen months.

• Step 1 · 1 · Know the gap. WHO's maps are for WHO ICD-10. ICD-10-CM is a modification, so check each use.
• Step 2 · 2 · Dual code. WHO recommends dual coding studies to find variation and impact.
• Step 3 · 3 · Overlap. Plan to run old and new in parallel for at least 18 months.

Check yourself

Pause and think. Why check any map against ICD-10-CM before using it? The answer: WHO maps are for WHO ICD-10 and ICD-10-CM is a modification. Know the gap: WHO's maps are for WHO ICD-10, and ICD-10-CM is a modification.

• Maps are never reliable
• ICD-10-CM has no codes
• WHO maps are for WHO ICD-10 and ICD-10-CM is a modification
• WHO maps are for ICD-9

Keep these in mind

Check any map against ICD-10-CM before using it. Dual coding studies measure the impact. And plan for parallel running.
