Certified Professional Coder CPC AAPC Study Notes

When a patient experiences an underdose of insulin due to an insulin pump malfunction, the primary reason for the encounter would be the malfunction itself, which is coded first. The resulting hyperglycemia or hypoglycemia due to the pump failure is a secondary condition. According to ICD-10-CM guidelines, the code for the mechanical complication of the pump (T85.633-) is sequenced first, followed by a code for the diabetes with complication (E11.65 for type 2 diabetes with hyperglycemia).

ICD-10-CM (current year), Chapter 19: Injury, Poisoning and Certain Other Consequences of External Causes (S00-T88), ICD-10-CM Official Guidelines for Coding and Reporting, Section I.C.4.

This scenario describes apalatoplasty(repair of cleft palate) withclosure of the alveolar ridgeusing abone graft. CPT code42210is the code that captures palatoplasty withclosure of the alveolar ridgeand associated bone grafting work as part of the reconstructive procedure described. Because the bone graft is part of the defined palatoplasty service in this code concept, you donotseparately report a generic bone graft harvesting code such as20900in the way the answer options suggest. The distractor42200is associated with a more limited palate repair (not matching the alveolar ridge closure with graft detail), and42205does not reflect the specific alveolar ridge closure with bone grafting described in the question stem. CPC exam strategy: identify the mostcomprehensive cleft palate repairthat matches the documentation; when a CPT code description includes the specific additional work (like alveolar ridge closure with graft), code that single comprehensive service.

Place of Service (POS) codes are two-digit numeric codes used on professional claims to identify where a service was performed (e.g., office, inpatient hospital, outpatient hospital).

Reporting an incorrect POS can affect reimbursement and may result in claim denial ✔

POS codes are not alphanumeric

They describe many locations, not just ICU

POS codes are maintained by CMS, not found in the ICD-10-CM code book

For the procedure involving access to the subclavian vein and advancing a catheter to the inferior vena cava for injection and imaging, the following codes are used:

36010 for the catheter placement.

75825-26 for the supervision and interpretation of the imaging.

Modifier -26 indicates the professional component of the radiological supervision and interpretation.
