Symptoms are not reported with definitive diagnosis

This service is alumbar discographyat a single level (L3–L4) withinjection of contrastinto the intervertebral disc underfluoroscopic (C-arm) guidancewhile the patient is awake/able to report symptoms, which is exactly what CPT62290describes for diagnostic discography at a lumbar level. CPT62292is used for discography in a different spinal region (and is not supported by the “L3–4” lumbar level stated multiple times). The post-discography CT scan is referenced as planned/reviewed but is not clearly documented as performed/interpreted as part of this same physician service in the stem, and it is not part of the answer choices. For ICD-10-CM, the confirmed postoperative finding is “normal discography,” but the reason for the study remains the patient’slow back painand suspected stenosis; in outpatient/procedural settings you code thereason for the testwhen the definitive suspected condition is not confirmed. Here, the stenosis was ruled out (“no evidence”), so donotcode spinal stenosis; reportM54.50for low back pain. Therefore,62290 with M54.50is correct.

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.

99291: This code is used for the first 30-74 minutes of critical care, evaluation, and management of the critically ill or critically injured patient.

99292: This code is used for each additional 30 minutes of critical care service beyond the first 74 minutes.

The documentation indicates that the patient received a total of 45 minutes of critical care, which involves continuous IV insulin for diabetic ketoacidosis, administration of antiemetics, and admission to the ICU. The critical care time documented justifies the use of 99291 for the first 30-74 minutes and 99292 for each additional 30 minutes.
