Moody had been out since last December after suffering a career-threatening stress fracture of the foot.
But he was in vintage form against the Italians, scoring two second-half tries in a performance that would have delighted national boss Andy Robinson.
England scrum-half hopeful Harry Ellis also scored twice, while Seru Rabeni scored the other try.
Calvisano's only reply came from fly-half Gerard Fraser, who kicked a penalty in either half.
Leicester coach John Wells, though, will not have been happy with his side's disjointed first-half showing.
The Italians arrived having shipped an average of 40 points in their four previous encounters with the Tigers. But Leicester appeared to have half an eye on the stiffer tests ahead against Pool One big guns Biarritz and Wasps.
They left Neil Back and Julian White on the bench and out of the steady rain. Alongside them was player-coach Richard Cockerill, called up as hooking cover following George Chuter's six-week stamping suspension.
Leicester grabbed a 14th-minute try from Ellis, who was bundled over after Rabeni's break had taken him close to the line.
Andy Goode converted and kept his side on the front foot with a series of searching kicks to the corners.
The Calvisano defence held against some predictably direct attacks and frustrated the hosts for the next 20 minutes until Goode thumped over a second penalty.
The visitors have a dogged reputation and made sure they stayed in the game by scoring with just about their only visit to Leicester territory when Fraser stroked over a penalty two minutes before the break.
Wells made only one change at half-time, replacing the under-employed Healey with the more dynamic Alex Tuilagi.
It took only five minutes for Leicester to add a second try, with Tuilagi involved on the right before Goode's long pass gave Rabeni a clear run to the line.
Cockerill, now 33, replaced James Buckland after 53 minutes and was immediately back into the old routine.
He found Martin Johnson with his first lineout throw and the Leicester pack rumbled towards the line before Ellis nipped round the blind-side for his second try.
Fraser responded with a penalty but the hosts were now in total control, emphasised on the hour when Moody was driven over in the right-hand corner and Goode converted.
Moody was celebrating again two minutes later when he was driven over for a
Goode's conversion made it 37-6 and Leicester were unlucky not to add to the
score as they continued to stretch the visitors in the final 10 minutes.
