Per NCCI guidelines, when a laparoscopic procedure is converted to an open procedure, only the open procedure is reported, so you would only code 58150. From the NCCI Manual: "If a procedure utilizing one approach fails and is converted to a procedure utilizing a different approach, only the completed procedure may be reported. For example, if a laparoscopic hysterectomy is converted to an open hysterectomy, only the open hysterectomy procedure code may be reported. If a laparoscopic procedure fails and is converted to an open procedure, the physician should not report a diagnostic laparoscopy in lieu of the failed laparoscopic procedure. For example, if a laparoscopic cholecystectomy is converted to an open cholecystectomy, the physician should not report the failed laparoscopic cholecystectomy nor a diagnostic laparoscopy."
And yes, 49000 is inclusive and also cannot be reported - it is designated as a 'separate procedure' so is always inclusive to any other procedure at the same site or incision.
