ICD-10-CM Clinical Coding
A real coding workbench, not a quiz: decode any ICD-10-CM code's anatomy, then code synthetic cases by searching the index and assigning a code — the engine checks billability, specificity, laterality and the 7th character.
A 58-year-old woman presents for routine follow-up. She has type 2 diabetes mellitus managed with metformin alone; HbA1c 7.1%. No nephropathy, retinopathy, neuropathy or peripheral vascular disease is documented.
Assign the most specific billable ICD-10-CM code for the primary diagnosis.
Search 'diabetes type 2'. E11 is the category — it is not billable on its own. The 5th character carries the complication status.
