Hypertension and Diabetes Combination Flowchart (ICD-10-CM Cheat Sheet)

A two-page flowchart for coding hypertension and diabetes in ICD-10-CM. Follow the arrows from "hypertension documented" to the right code, with every add-on code you need, then work through diabetes one step at a time.

WHAT'S INSIDE

• Page 1: the "with" rule and when it doesn't apply, a decision flowchart for I10, I11, I12, and I13 (heart disease, heart failure, CKD stage 1 to 4 or 5 and ESRD), the add-on codes people forget (CKD stage, heart failure type, dialysis status, resistant hypertension), and what doesn't follow the I10 to I13 path (hypertensive crisis, elevated reading, secondary hypertension, acute kidney failure, pregnancy)
• Page 2: four steps for any diabetes case, a map of the type 2 codes by body system, the newer codes (E11.A remission, E10.A presymptomatic type 1, E16.A hypoglycemia level), drug code rules for Z79.4, Z79.84, and Z79.85, and 6 worked examples, including diabetes, hypertension, heart failure, and CKD together

Each rule is tagged to its section of the ICD-10-CM Official Guidelines or the Tabular List, so you can read the full text in your book. Made for risk adjustment, outpatient, and inpatient coders, and anyone studying for a coding exam.

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 guide covers ICD-10-CM diagnosis coding only. It has no CPT procedure codes and no HCC model numbers.
• 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.
