Partial ureterectomy (removal of part of the ureter).

CPT® Coding:

50220: Nephrectomy, including partial ureterectomy, any open approach.

AMA ' s CPT® Professional Edition (current year).

33779 = Arterial switch operation (definitive repair)

33955 = Open central cannulation for ECMO

33985 = ECMO management

Modifier -58 = staged/related procedure

Modifier selection for discontinued procedures depends onsettingandhow far the procedure progressed. In the CPT modifier framework,-53(Discontinued Procedure) is used when a physician terminates a procedure due toextenuating circumstances or those that threaten the well-being of the patientafter the procedure has begun. Here, anesthesia was given, the incision was made, and then respiratory distress occurred—clearly a patient safety issue requiring stopping the surgery. That matches modifier-53for the surgeon’s claim. Modifier-74is afacilitymodifier (commonly used by ambulatory surgery centers/hospitals for discontinued outpatient procedures after anesthesia), not the surgeon’s CPT modifier in the typical CPC context. Modifier-47indicates anesthesia by the surgeon, which is not the key fact here and does not represent discontinuation. Modifier-52is for reduced services when a service is partially reduced at the physician’s discretion, not terminated for patient safety. Therefore, the oral surgeon reports21060-53.

1. E/M Code Category Selection:

The patient was placed in observation care on 12/2/20XX for an acute asthma exacerbation and stayed in observation for a total of 16 hours, with discharge occurring on 12/3/20XX.

The appropriate E/M category for patients in observation care for a period that includes both admission and discharge on separate calendar dates is " Hospital Inpatient or Observation Care Services " , with specific codes for admission and discharge on different dates.

2. Code Range and Specific Codes:

Code Range 99234-99236 applies to cases where observation care includes both admission and discharge, particularly when they occur on different calendar days and the total duration of care is under 24 hours.

For discharge on the subsequent day, 99238-99239 (Hospital Inpatient or Observation Discharge Services) applies, depending on the time spent on discharge.

3. Rationale for Excluding Other Options:

Option B and Option D include Initial Hospital Inpatient or Observation Care codes (99221-99223), which are typically used for admissions to inpatient care rather than for observation care scenarios as presented here.

Option C incorrectly combines Subsequent Inpatient or Observation Care codes (99231-99233), which are used for follow-up days rather than discharge services.

4. AAPC and CPT® Coding Guidelines:

According to CPT® guidelines, the 99234-99236 code range is used when observation care requires both admission and discharge on different dates, and 99238-99239 is appropriate for discharge services.

Therefore, the correct answer is A. Hospital Inpatient or Observation Care Services (Including Admission and Discharge Services) (99234-99236) and Hospital Inpatient or Observation Discharge services (99238-99239).
