Section identifier 9 in ICD-10-PCS reports which of the following?

The section identifier 9 in the ICD-10-PCS coding system corresponds specifically to chiropractic procedures. This coding system is structured into distinct sections that categorize procedures based on their respective areas of medicine.

Chiropractic procedures are included under this section as they encompass treatments and manipulations performed by chiropractors to diagnose and manage musculoskeletal conditions, particularly those related to the spine.

The other options refer to different sections in ICD-10-PCS: orthopedic procedures deal with the treatment of musculoskeletal issues but are categorized in a different section, radiological procedures pertain to imaging and diagnostic procedures, and cardiovascular procedures focus on interventions related to the heart and blood vessels. Each of these fields has its respective section code that differentiates them from chiropractic procedures, which is why the section identifier 9 is specifically linked to chiropractic interventions.
