a)
If the physician provides "Consultation service" by three criteria of consultation, should be billed as "Outpatient Consultation"99241-99245. But if the same physician on same DOS, ADMITS the patient into OBSERVATION STATUS, and does the e/m as per Observation Coding criteria, then Consultation services should not be billed and only INITIAL OBSERVATION CARE should be billed.
b)
If the consultation service doesn't justify three criteria of consultation, then it should be billed as ED codes 99281-99285 if there is no Observation care on same DOS. But if the same physician on same DOS, ADMITS the patient into OBSERVATION STATUS, and does the e/m as per Observation Coding criteria, then ED codes should not be billed and only INITIAL OBSERVATION CARE should be billed.

an example is given below which is similar to your 2nd question. Plz refer to the examples:

When another practitioner requests your orthopedic surgeon’s opinion about a patient’s condition, you should report a consult code.
*
Example: A patient presents to her primary-care physician (PCP) complaining of shoulder pain. The PCP cannot establish a diagnosis and asks an orthopedic surgeon to evaluate the patient and give his opinion regarding the patient’s condition and possible treatment methods. The orthopedic surgeon examines the patient, determines that she has a torn rotator cuff (840.4), and recommends arthroscopic repair (29827, Arthroscopy, shoulder, surgical; with rotator cuff repair). He sends the PCP a report with his diagnosis and his recommendation.
The orthopedist’s service qualifies as an office consultation, and you should report the appropriate code from the 99241-99245 range.
*
Referrals: No request, no report. A referral, on the other hand, is the transfer of responsibility for a patient’s care from one physician to another, says Marvel Hammer, RN, CPC, CHCO, owner of MJH Consulting in Denver.
*
Example: A 23-year-old woman with severe knee pain reports to her internist. The internist orders an MRI, and the radiology report indicates that the patient has a torn medial meniscus (836.0). The internist refers the patient to the orthopedic surgeon for surgical repair. Because the internist does not ask the orthopedist to render an opinion on the patient’s condition, the orthopedic surgeon should code his service with a new patient office visit code (99201-99205).
