Home Health Bill Type 32A Returning With Reason Code U537I


CMS implemented HH TOB 32A for the NOA effective for period of care claims on or after 1/1/2022. The NOA is required for all HH period of care claim billing, including demand billing (0329 TOB with cc 20) and no-pay, or insurance denial, billing (0320 TOB with cc21). It is important to ensure the NOA is billed within five calendar days of the start of care and processed prior to submitting any claim billing. If a claim has returned with the U537I reason code because there is not a processed 32A NOA in the system, the NOA must be submitted. Once it has processed, the returned claim can be resubmitted for processing.
