GOOD TO KNOW

• Based on the FY2027 ICD-10-CM code set and Official Guidelines (in effect October 1, 2026 to September 30, 2027). Codes change every October, so check the current year.
• This sheet covers ICD-10-CM diagnosis coding only. It has no CPT procedure codes and no DSM-5-TR criteria.
• Educational reference, not legal or billing advice. Payers and facilities can add their own rules.
• AAPC doesn't allow extra notes or printouts in exam code books, so this is a study aid and work reference, not an exam aid.
• Not affiliated with or endorsed by CMS, NCHS, AHA, AAPC, or AHIMA.
• Digital items generally can't be returned. If a file is missing, damaged, or different from this listing, email thedenialdesk@gmail.com and I'll help sort it out.
• Drafted with help from AI tools, then reviewed and fact-checked by a certified medical coding professional.
