Global Healthcare Resource's General Manager of Coding Quality, Viba Raghavendran (CPC) and General Manager of Coding Operations Sivashankari Thangavelu (CPC,BCHHC,RCC & CCS) share helpful rule reminders and coding information for specific medical conditions.

Reimbursements & Research

To revenue cycle professionals, ICD-10 codes are the universal language between providers and payers to communicate appropriate reimbursements. While this is accurate, ICD-10 codes (and their continuous updates) also provide researchers with higher levels of clinical detail that aid in improvements to treatment and technology. This data has further impact on healthcare policy, treatment recommendations and resource allocation.

This year brings several ICD-10 changes; however, we will be focusing on Chapter 13: Diseases of the Musculoskeletal System and Connective Tissue


Chapter 13: Diseases of the Musculoskeletal System and Connective Tissue

Chapter 13 has several updates this year including twelve new codes to capture other pathological fractures (M80.8AX- and M80.0AX-). Updates include an expanded list of codes for rheumatoid arthritis, as well as primary and secondary arthritis and arthritis caused by trauma. New codes in the M24 category for other articular cartilage disorders, disorders of ligament, pathological dislocation, recurrent dislocation, contracture and ankylosis.

In Chapter 13, all the categories below have new codes with “other specified site” in the descriptor.
