Pregnancy Coding at a Glance (ICD-10-CM Cheat Sheet)

A two-page quick reference for coding pregnancy, childbirth, and the puerperium in ICD-10-CM (Chapter 15, O00-O9A). Every rule is tagged with its Official Guidelines section, so you can check it in your book.

WHAT'S INSIDE

• Page 1: the ground rules (Chapter 15 first, mother's record only, incidental pregnancy Z33.1), a trimester bar with the exact week cutoffs, how to pick the trimester character (including stays that cross trimesters), a "which code goes first" flow for prenatal, high-risk, complication, delivery, and postpartum visits, the fetus 7th character and the categories that use it, Z3A weeks of gestation rules, and the postpartum and peripartum periods with O90.3 and O94
• Page 2: O80 normal delivery rules, Z37 outcome of delivery, pre-existing vs. pregnancy-related diabetes and hypertension (O24, O10, O11, O13, O14, O99), which O code goes first for HIV, COVID-19, poisoning, abuse, alcohol, tobacco, drugs, and puerperal sepsis, what's new for FY2027, and 6 worked examples

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 does not cover the global obstetric package.
• 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.
