Free ICD-10 claim scrubber
Paste the diagnosis codes from a claim and get back what would reject it: Excludes1 conflicts, non-billable header codes, missing 7th characters, laterality contradictions, and unmet sequencing rules.
Free DRG calculator
Enter the diagnoses with POA and the procedures and get the MS-DRG CMS assigns, medical or surgical: which procedure and which secondary set it, the DRG family with weights, and what a documented CC or MCC would change.
Free HCC lookup
Paste the diagnosis codes from a chart and see which ones risk-adjust under CMS-HCC V28: the category, its coefficient, the age and sex edits, and which captured HCCs the hierarchy would zero.
Denial appeal letter generator
