Final answer:
ICD-10-CM codes should be reported for the pre-operative clearance. The specific codes will depend on the findings of the screening and any related diagnoses or conditions.
Step-by-step explanation:
According to ICD-10-CM guideline IV.M, when a patient requires pre-operative clearance for a surgery, it is important to report the ICD-10-CM codes that describe any conditions or diseases that the patient may have. In this case, the patient is scheduled for a splenectomy for hypersplenism, so the pulmonologist would perform a pre-operative screening to assess the patient's respiratory health. The ICD-10-CM codes reported for the pre-operative clearance would depend on the specific findings of the screening and any related diagnoses or conditions that are identified.
