I do not know of any "official" sources that specifically address bilateral procedures. There are official sources for medical record documentation, such as:
But these "official" sources do not specifically address what is required when documenting a bilateral procedure. In my experience, a physician statement that the procedure was performed on the opposite (contralateral) side in the same manner/fashion as the first side has been sufficient and I have never had an insurance carrier deny reimbursement for bilateral procedures with that type of statement. Having said that, if the second side was not done in EXACTLY the same manner/fashion as the first side, then specific documentation as to how it was done differently would be required.
AHIMA has a clinical example in one of their training texts that supports this type of documentation, which is the closest I have found to any "official" source (

Operative Report
Preoperative Diagnosis: Thrombosed hemorrhoids
Postoperative Diagnosis: Same
Indications: This 25-year-old female, one week postpartum, complains of extremely painful hemorrhoids. Examination revealed circumferential prolapsed hemorrhoids with partial thrombosis in multiple areas.
Procedure: After induction of general anesthesia, she was prepped and draped in the usual sterile fashion. The patient was placed in lithotomy position and a retractor was placed in the anus. Very prominent, large, partially thrombosed external hemorrhoid was identified at 7-8 o'clock in the lithotomy position. It was grasped with a hemorrhoidal clamp. A 2-0 chromic stitch was placed at the apex. The Bovie electrocautery was then used to elliptically excise the large hemorrhoid, staying superficial to the sphincter muscle. Bleeding was controlled with Bovie electrocautery. The mucosa was closed with a running chromic stitch, leaving the end-point epidermis open.
Two other very large external hemorrhoids with thrombosis were then identified, at the 5 o'clock position in lithotomy and at the 10-11 o'clock position. These two hemorrhoids were excised in the exact same fashion as the first hemorrhoid. At the conclusion, there was no evidence of bleeding. The patient was returned to the recovery area in good condition.
