ICD-10-CM and ICD-10-PCS Coding Handbook 2025 With Answers

ICD-10-CM and ICD-10-PCS Coding Handbook 2025 is the only guide published in collaboration with the Central Office on ICD-10-CM/PCS of the American Hospital Association. ICD-10-CM and ICD-10-PCS are the HIPAA code set standard for diagnosis and inpatient procedures in the United States, and AHA’s ICD-10-CM and ICD-10-PCS Coding Handbook is the preeminent resource for ICD-10 medical coding students and coding professionals.

ICD10 Coding Handbook content reflects revisions of the Official Guidelines for Coding and Reporting as well as AHA Coding Clinic for ICD-10-CM and ICD-10-PCS content, updated annually. The format and style of presentation in the ICD-10-CM and ICD-10-PCS Coding Handbook With Answers 2025 follows that of previous editions inspired by the Faye Brown approach to coding instruction. The text leads students to logical answers and provides primary supporting sources. This logical approach has enabled the Handbook to become the most popular textbook for training hospital and physician office coding professionals, along with intermediate coding students.

Useful appendices found in the ICD-10-CM and ICD-10-PCS Coding Handbook:

• Appendix C — comprises advanced case examples based on actual health records and includes code-assignment explanations. 
• Present on Admission Indicator — Additional appendixes explain coding and reimbursement methodologies and reporting of the present on admission indicator—valuable information for new coding students.
