UB04 Type of Bill Code 0211: Skilled Nursing - Inpatient (Medicare Part A) - Admit through Discharge Claim

Overview

The UB-04 Type of Bill code 0211 identifies a claim from a Skilled Nursing Facility (SNF) for Inpatient Part A care, submitted as a single claim covering the entire stay from admission through discharge. According to the Noridian Bill Types guidance, the four-digit code structure (after a leading zero) conveys three pieces of information: the second digit indicates the type of facility (2 = Skilled Nursing Facility), the third digit indicates the type of care (1 = Inpatient Part A), and the fourth digit indicates the sequence/frequency (1 = Admit Through Discharge) ^[1]. This code is used exclusively for Medicare Part A covered SNF stays that are billed as a complete episode without interim or continuing claims.

When to Use

Use 0211 when a SNF provides Medicare Part A covered inpatient care to a beneficiary and the provider is submitting a single claim that encompasses the entire period from the date of admission through the date of discharge. The Noridian guide specifies that frequency digit “1” means “Admit Through Discharge” ^[1]. This code is appropriate for stays that do not require interim billing (e.g., no beneficiary transfer to another Part A facility, no change in payer mid-stay, and the stay is complete before billing). If the SNF is billing for Medicare Part A services but only a portion of the stay (e.g., the first or interim period), codes 0212 (Interim – First Claim), 0213 (Interim – Continuing Claims), or 0214 (Interim – Last Claim) would be used instead. Code 0211 is also not used for non-payment/zero claims (frequency 0) or late charges (frequency 5) ^[1].

Step-by-Step Claim Example

Assume a Medicare beneficiary is admitted to a SNF on April 1, 2026, for a Part A covered stay and discharged on April 15, 2026. The SNF prepares a UB-04 claim for the entire stay.

• Field 4 – Type of Bill: Enter 0211. The leading zero is ignored by CMS. Digit “2” indicates Skilled Nursing Facility, digit “1” indicates Inpatient Part A, and the final “1” indicates this claim is for the entire Admit Through Discharge period ^[1].
• Other fields: The claim includes the beneficiary’s Medicare HIC number, admission date (04/01/2026), discharge date (04/15/2026), covered days (14), and all revenue codes and charges for Part A covered services (e.g., room and board, therapy, nursing).

After submission, the Medicare Administrative Contractor (MAC) processes the claim as a complete stay, applying the appropriate SNF Part A prospective payment system (PPS) rate. No interim claims are needed because the stay was billed in full using code 0211 ^[1].

Common Mistakes & Audit Red Flags

• Using 0211 for partial stays: If a SNF bills an interim first or continuing claim with frequency 1 instead of the correct interim code (2 or 3), the MAC may reject or down-code the claim. Noridian makes clear that frequency 1 is reserved for “Admit Through Discharge” only ^[1].
• Incorrect type of care digit: Using code 0211 when services are actually Part B (e.g., outpatient therapy in a SNF) is a common error. Third digit “1” strictly means Inpatient Part A; Part B inpatient would be code 0221 ^[1].
• Mixing frequency digits: Submitting an 0211 claim after previously billing an interim claim (e.g., 0212 then 0214) duplicates billing and may trigger an audit. Frequency 1 should only appear once per stay.
• Billing non-covered days: Code 0211 includes the entire stay; if some days are not covered under Part A, providers must use a different frequency (e.g., 0210 for non-payment) or adjust as needed.

Related Codes/Fields

The table below shows related Type of Bill codes for Skilled Nursing Facility inpatient Part A claims, based on the Noridian frequency definitions ^[1]. All codes share facility digit “2” and care digit “1”.

Code	Frequency Digit	Meaning
0210	0	Non-payment/Zero Claim
0211	1	Admit Through Discharge
0212	2	Interim – First Claim
0213	3	Interim – Continuing Claims
0214	4	Interim – Last Claim
0215	5	Late Charge Only
0217	7	Replacement of Prior Claim
0218	8	Void/Cancel of Prior Claim
0219	9	Final claim for Home Health PPS Period (rare for SNF)

Note: Additional frequencies (A through Z) exist for hospice, adjustments, and other special situations, but are not commonly used for routine SNF inpatient Part A stays ^[1]. For a complete list of all frequencies, refer to the Noridian guidance.
