Type of Bill 32X

Type of bill is a code reported on institutional claims, commonly written with a leading zero, such as 0329. Reading 32X: the 3 identifies home health as the facility type, the 2 identifies the classification for services under a home health plan of care, and the final character is the frequency code that defines the transaction. The frequency character is where billers live day to day, because it distinguishes an admission notice from a payment claim from a correction, and using the wrong one produces rejections or unintended replacements of prior claims.

A handful of 32X variants cover nearly all home health billing:

• 32A: the Notice of Admission (NOA), filed once per admission within 5 calendar days of the start of care
• 329: the original final claim for a 30-day payment period
• 327: an adjustment (replacement) of a previously processed claim
• 328: a cancellation of a previously processed claim
• 320: a nonpayment claim, used in no-pay situations such as reporting for a beneficiary with no payable coverage

Historically, 322 identified the Request for Anticipated Payment (RAP), which was retired when the NOA replaced it in January 2022.

Not everything a home health agency bills rides on 32X. The 32X family is specifically for services furnished under a home health plan of care, the services paid through the prospective payment system. Certain services an agency furnishes outside a home health plan of care are billed on type of bill 034X instead, following different payment rules. The distinction keeps the PDGM payment machinery, NOAs, sequential billing, HIPPS codes, pointed only at plan-of-care claims. Billers moving from other settings should also note that hospice, outpatient, and facility claims use entirely different bill type families, so cross-setting habits do not transfer.

Most type of bill errors are frequency-code errors. Submitting a 329 when the NOA has not been accepted gets the claim caught in sequential billing edits. Using a cancellation (328) when an adjustment (327) was needed removes the original claim entirely and forces a rebill, extending payment delays. Adjusting a claim in the middle of an admission can also ripple through the sequence behind it. The working rules: confirm the NOA status before billing finals, adjust rather than cancel unless the claim should never have existed, and check the remittance to verify which transaction Medicare actually processed.
