Tuberculosis (TB) can usually spread from the lungs to another site via the bloodstream.
Because the documentation does not specify whether the TB is primary or secondary, the coder would default to A15.9, as TB unspecified. A cough and fever are symptoms of an underlying illness and would not be coded because a definitive diagnosis of TB is present. Because TB is an HIV- related illness, B20 would be the first listed code.

To determine which services to report for this encounter, it is important to understand which services were rendered on the last. The patient had an open biopsy of the axillary lymph nodes (CPT 38525) last week This procedure has a postoperative 90-day global period. This means that any related services provided to the patient within that time are reported with zero-charge CPT
99024. Services such as biopsy results, follow-up incisional care, and any postoperative complications are all inclusive to this code. As the patient was given biopsy results, CPT 99024 should be reported for this encounter. However, CPT guidelines also state that when it comes to diagnostic procedures, "care of the condition for which the diagnostic procedure was performed...
is not included and may be listed separately." In this case, that care begins with the discussion of treatment options with their identified risks, and the decision to begin radiation. This level of moderate medical decision-making is reported by means of E/M CPT 99214. Modifier 24 is appended to indicate that is it unrelated to postoperative care, and modifier 25 is appended to indicate it is separately identifiable to CPT 99024. ICD-IO-CM crosswalk for lymphoma, diffuse large cell, is C83.34.

Photodynamic therapy applies a photosensitizing agent by either an external or endoscopic application. An external application is applied directly onto a patient's lesions, whereas an endoscopic application is an injection into the bloodstream, where it is absorbed by cells all over the body. Based on this differentiation, the documentation supports only an endoscopic application.
The code notes for CPT 96570 and 96571 indicate they are add-on codes to the bronchoscopy procedure, which is represented by CPT 31641. Any drug administration is inclusive to photodynamic therapy, making CPT 96409 not separately billable.

The documentation demonstrates that the number and complexity of problems addressed is low (fatigue and muscle aches are self-limited problems), the amount or complexity of data to be reviewed and analyzed is moderate (three unique tests), and the risk of complications, morbidity, or mortality of patient management is minimal (the patient was advised to drink more water). (To determine the final level of medical decision making, choose the lowest of the highest two elements. In this scenario, the final level of medical decision making is low, and the CPT code is
99213. Vihen reporting a routine venipuncture, use CPT code 36415. CPT code 36410(a) is reported when it is medically necessary for the physician to draw a patient's blood, and 36416 describes capillary blood collected through a skin prick-certainly not enough to fill two vials. CPT code 99000 can be used to report a specimen being transported to an outside laboratory, but that is unknown in this scenario. A generic urinalysis is reported with CPT code 81002 unless specifically stated that an automated analyzer (81005), a commercial kit (81007), and/or an agar test (81020) was utilized.

When leveling a visit based on the documentation, the lower of the two highest components should be used to determine the level of complexity. In this case, because the number and complexity of problems addressed is moderate and level of risk of complications and/or morbidity or mortality of patient management is low, the MDM is low. On the other hand, because total time is documented and would constitute a higher level of service, total time should be used to select CPT
99214.
