AAPC Updated CPC Exam Questions and Answers by avie

In medical billing, Place of Service (POS) code 31 is used to indicate that a service was performed in a skilled nursing facility (SNF). POS codes are standardized by the Centers for Medicare & Medicaid Services (CMS) to specify the location where services are provided.

A. 32 refers to a nursing facility (NF), which is different from a skilled nursing facility in terms of the level of care provided.

B. 20 indicates urgent care facility.

C. 22 is used for outpatient hospital services.

Thus, the correct answer is D. 31 for a skilled nursing facility.

1. Procedure and CPT® Code Selection:

The patient delivered her second child vaginally after having a previous cesarean delivery for her first child. This scenario describes a Vaginal Birth After Cesarean (VBAC).

CPT® Code 59610 is specific for a vaginal delivery after a previous cesarean delivery, including antepartum and postpartum care with the same provider, which matches this case exactly.

2. Rationale for Excluding Other Options:

Code 59410 covers only vaginal delivery with postpartum care but does not include a history of previous cesarean delivery, so it is not appropriate for a VBAC.

Code 59400 is for routine vaginal delivery with antepartum and postpartum care but, again, does not account for a previous cesarean, so it does not apply in this VBAC scenario.

Code 59614 is for a VBAC but does not include antepartum care, making it incomplete for this scenario since the question specifies that antepartum, delivery, and postpartum care were provided by the same provider.

3. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines indicate that 59610 should be used for a complete VBAC service that includes antepartum, delivery, and postpartum care by the same provider.

Therefore, based on CPT® guidelines, the correct answer is B. 59610.

In the ICD-10-CM Tabular List,parentheses ( )are used to enclosenonessential modifiers, also described assupplementary words. These are words thatmay be present or absentin the diagnostic statement without affecting code assignment. This is exactly why parentheses are associated with synonyms, alternative wording, or explanatory phrases. If the provider documents the core diagnosis and the parenthetical term is missing, the code can still be correct; if the parenthetical term is present, it still points to the same code. By contrast, acolon (:)is used after an incomplete term that needs one or more additional terms to make it assignable.Brackets [ ]have other specific functions (such as enclosing synonyms in certain contexts and used with instructional content), but the standard CPC-tested definition for “synonyms/alternative wording/explanatory phrases” in the Tabular List points toparenthesesas nonessential modifiers. Knowing this distinction supports accurate code selection and reduces errors when provider wording varies.
