CPC Review - ICD-10-CM Chapters 12-22 Study Refresher and Practice Questions

Summary

This video provides an in-depth review of ICD-10-CM codes, focusing on chapters 12 to 22, which cover a wide range of medical conditions. Topics include diseases of the skin, musculoskeletal system, genitourinary system, pregnancy, congenital malformations, and more. The video also highlights key concepts for coding correctly, such as documentation requirements, laterality, staging, and specific conditions like osteoarthritis, chronic kidney disease, pressure ulcers, and hypertension in pregnancy. Additionally, the video includes practice questions to reinforce coding techniques and strategies for CPC exam preparation.

Takeaways

• 😀 Chapter 12 focuses on diseases of the skin and subcutaneous tissue, highlighting conditions like cellulitis, dermatitis, and pressure ulcers.
• 😀 For cellulitis, it's crucial to document laterality and location to select the most specific code, such as L03.115 for cellulitis of the right lower limb.
• 😀 Dermatitis is differentiated by type and causative agent, and external cause codes may be needed, like L24.2 for irritant contact dermatitis due to solvents.
• 😀 Pressure ulcers are commonly tested in the CPC exam and require accurate documentation of site, laterality, and stage (1-4). If the stage can't be determined, it’s considered unstageable.
• 😀 Chapter 13 covers musculoskeletal system conditions like osteoarthritis, fractures, and rheumatoid arthritis, focusing on laterality and underlying causes for fractures.
• 😀 Chronic kidney disease (CKD) is classified by stages, with important codes like N18.4 for stage 4 CKD, which must be carefully documented for accurate coding.
• 😀 Pregnancy-related conditions in Chapter 15 take sequencing priority and require careful documentation, such as hypertension during pregnancy and gestational diabetes.
• 😀 Chapter 16 addresses perinatal conditions, including birth trauma and congenital infections, with Z38 used to identify live births and specify the type and place of delivery.
• 😀 Chapter 17 covers congenital malformations, where conditions like spina bifida and Down syndrome must be documented, along with any associated conditions.
• 😀 The Z codes in Chapter 21 are used for factors influencing health status, such as screening and preventive services, and personal history codes like Z94 for organ transplant status.

Q & A

What is the purpose of this video?

The video serves as a review of ICD-10-CM materials for medical coding, particularly focusing on chapters 12 through 22, to assist viewers in preparing for certification exams or refreshing their medical coding knowledge.

How does the ICD-10-CM curriculum in this video differ from the AAPC's curriculum?

The ICD-10-CM breakdown in the video follows a three-chapter structure, while the AAPC curriculum organizes the material into two chapters. Both approaches offer beneficial information for medical coding certification, but this video provides a step-by-step breakdown to aid in understanding.

What are the three key diagnoses to focus on in Chapter 12 (Diseases of the Skin and Subcutaneous Tissue)?

The three key diagnoses in Chapter 12 are cellulitis, dermatitis, and pressure ulcers. These conditions are essential to understand, particularly in relation to documentation for laterality, location, and staging.

How should cellulitis be coded correctly?

When coding for cellulitis, it's important to include documentation for laterality (right or left) and location to select the most specific code, such as L03.115 for cellulitis of the right lower limb.

What is the difference between 'unstageable' and 'unspecified' when coding for pressure ulcers?

'Unstageable' refers to a pressure ulcer where the stage cannot be determined due to tissue covering the wound, while 'unspecified' refers to cases where the stage is not documented, but the stage can potentially be determined.

How is osteoarthritis of the knee coded in ICD-10-CM?

Osteoarthritis of the knee is coded based on the site and laterality. For example, primary osteoarthritis of the right knee is coded as M17.11.

What factors are important when coding for chronic kidney disease (CKD)?

When coding for CKD, it's crucial to identify the stage of the disease, which ranges from stage 1 to end-stage renal disease. For example, stage 4 CKD is coded as N18.4.

What is the importance of sequencing pregnancy codes (Chapter 15)?

Pregnancy-related conditions in Chapter 15 take sequencing priority over all other codes. This is essential for accurate coding of pregnancy, childbirth, and related conditions, including the use of codes like Z3A to specify weeks of gestation.

How should a pressure ulcer with multiple stages and locations be coded?

A pressure ulcer with different stages and locations requires separate codes for each stage and site. For example, a stage 3 ulcer on the left heel and a stage 2 ulcer on the left hip would need two different codes.

What are the Z codes in Chapter 21 used for?

Z codes in Chapter 21 are used to document factors influencing health status and contact with healthcare services, such as screenings, personal history, family history, and organ transplant status.
