`Z43.2`, Encounter for attention to ileostomy

ICD-10-CM

No Prior Auth Required

Code is covered without prior authorization (high confidence)

A face-to-face encounter and a Written Order Prior to Delivery (WOPD) are required for specified HCPCS codes per Final Rule 1713 and the LCD-related Standard Documentation Requirements Article (A55426); claims missing these will be denied.
For quantities of supplies that exceed the usual maximum amount, the medical record must explain the need for the increased amount and be available upon request.
Initial justification for medical need must be established at the time the ostomy item is first ordered; once initial need is established, ongoing need is assumed and no further documentation is required as long as the beneficiary continues to meet the Prosthetic Devices benefit.
Claims for tape and adhesive (A4450, A4452, A5120) must include an AU modifier or another appropriate modifier indicating alternate coverage; absence of such modifier will cause rejection for missing information.

Ostomy supplies are covered under the Prosthetic Device benefit for beneficiaries with a permanent impairment requiring an ostomy; permanence means a condition of long and indefinite duration as documented by the treating practitioner.
Ostomy supplies are covered for use on beneficiaries with a surgically created opening (stoma) to divert urine or fecal contents, including colostomy, ileostomy, and urinary ostomy.
