Medicare Scribe Documentation Requirements:
Signatures, Attestation, and Physician Responsibility
Under CMS policy, a medical scribe whether human or AI-assisted is not required to sign or date a Medicare medical record entry. The treating physician or non-physician practitioner (NPP) must sign and date the documentation to authenticate it. Physician signature alone is sufficient; no separate attestation statement is required in a standard scribe arrangement.
Why These Rules Matter for Every Physician Using a Scribe
For physicians and practice managers evaluating medical scribe services, the compliance question comes up quickly: who is actually responsible for the chart? The answer has real consequences. Medicare claims can be denied when documentation does not meet signature requirements, and the physician not the scribe bears that responsibility.
CMS guidance on this point has been in place since 2017 and was reaffirmed in the updated MLN Fact Sheet published in July 2025. The core principle is straightforward, but the application across different situations missing signatures, illegible signatures, AI-assisted documentation, NPPs acting as scribes, and amendment workflows requires a closer look.
Key takeaways:
- A scribe (human or AI) is not required to sign or date the note under CMS rules.
- The treating physician or NPP must sign and date every scribed entry to authenticate it.
- No attestation statement is needed in a standard, properly documented scribe arrangement.
- Attestation is available as a remedy for missing or illegible physician signatures — it is not a substitute for a physician’s timely review.
MAC-specific guidance may add documentation expectations beyond the CMS baseline.
What CMS Actually Says
About Scribe Signature Requirements
The authoritative source is the
CMS Medicare Program Integrity Manual (Publication 100-08), Chapter 3, Section 3.3.2.4, as updated through CMS Change Request (CR) 10076 (Transmittal 713, May 2017) and reaffirmed in the
CMS MLN Fact Sheet MLN905364, updated July 2025.
Scribes are not providers of items or services. When a scribe is used by a provider in documenting medical record entries (e.g. progress notes), CMS does not require the scribe to sign/date the documentation. The treating physician’s/non-physician practitioner’s (NPP’s) signature on a note indicates that the physician/NPP affirms the note adequately documents the care provided.” — CMS CR10076 (Transmittal 713), cited by Noridian, CGS, and all major MACs
The July 2025 MLN Fact Sheet expanded this explicitly to AI-assisted documentation, stating: “If you use a scribe, including artificial intelligence technology, sign the entry to authenticate the documents and the care you provided or ordered. You don’t need to document who or what transcribed the entry.”
In plain terms: regardless of whether a human virtual scribe or an
AI scribing tool drafts the note, the physician must personally sign and date it. The scribe’s identity does not need to be documented under federal CMS policy, though some MACs recommend it as a best practice.
Physician Responsibility: What Signing the Note Actually Means
When a physician signs a scribed note, that signature is not a formality. It represents the clinician’s affirmation that:
- The note accurately reflects the care they provided or ordered.
- The documentation meets the medical necessity and coverage requirements for the billed service.
- They have reviewed the scribed entry and stand behind its content.
This means the physician cannot simply co-sign a note without reading it. A rubber-stamp approach to physician authentication creates compliance exposure regardless of how well the scribe documented the encounter. Physician review is not optional it is what makes the signature meaningful.
The scribe’s role is to record. The physician’s role is to verify, attest through signature, and take responsibility for the medical record.
This distinction matters particularly for Medicare billing. Reviewers during audits whether conducted by MACs, Recovery Audit Contractors (RACs), Unified Program Integrity Contractors (UPICs), or the CERT program are looking for the treating physician’s or NPP’s signature and date on the note. Claims reviewers are instructed not to deny claims solely because a scribe has not signed or dated the note.

When Is a Signature
Attestation Statement Needed?
A signature attestation is not a routine requirement simply because a human or AI scribe prepared a note. It may be used to address certain missing or illegible signatures when CMS rules permit it.
1. Missing signature on a medical record
When a required signature is missing from medical documentation other than an order, CMS may accept an attestation from the author of the record, subject to applicable requirements.
The practice should verify that the attestation is associated with the relevant record, identifies the author and entry, and meets the applicable policy. CMS may consider attestations created after the original entry unless a regulation or policy requires the signature to be in place before a particular event or date.
An attestation must not be used to backdate a plan of care or bypass a requirement that a signature be obtained at a specified time.
2. Illegible signature
If a signature is present but its author cannot be identified, CMS guidance allows a signature log or attestation to help establish the signer's identity, subject to the applicable rules.
A signature log generally associates a practitioner's name with their signature. Practices should retain appropriate supporting documentation and follow their MAC's instructions when responding to a medical review request.
3. When attestation is not an appropriate substitute
CMS does not accept a signature attestation as a substitute for a required signature on an order. Attestation also cannot override a rule that requires authentication before a particular event or date.
For the applicable exceptions and details, consult the
CMS Medicare Signature Requirements fact sheet.
MAC-Specific Guidance:
What Individual Contractors Recommend
While the CMS baseline under CR10076 applies nationally, individual Medicare Administrative Contractors have published supplemental guidance that practices should review. The ACEP Scribe FAQ (updated April 2021) compiled MAC-level policies, and the following patterns are common across jurisdictions:
Noridian (Jurisdictions E, F, J, DME A/B): Follows CMS CR10076 directly. Reviewers shall not deny claims because a scribe has not signed or dated a note.
CGS (Jurisdictions 15, JC): Emphasizes that the real-time transcription must be clearly documented by both the scribe and the physician, and that failure to comply with documentation instructions may result in claim denial.
Novitas (Jurisdictions H, L): Recommends documenting who performed the service and the scribe’s identity within the note. Sample language: “[scribe name] scribing for [physician name].”
National Government Services (Jurisdiction 6): Requires a notation that identifies the scribe as “acting as scribe for Dr. ___” and that the physician co-signs indicating the note accurately reflects the provider’s words and actions.
Palmetto GBA (Jurisdictions J, M): Notes that a scribe does not have to be an employee of the physician/NPP.
Practical takeaway: Because MAC guidance varies and
changes over time, practices billing Medicare should check their specific MAC’s current website for scribe documentation guidance in addition to the CMS baseline policy. Confirm which MAC covers your jurisdiction at cms.gov.

Virtual Medical Scribes and
Medicare Documentation: How the Workflow Fits
A virtual medical scribe joins a patient encounter remotely via a secure, HIPAA-compliant connection and documents the visit in real time directly within the physician’s EHR. From a Medicare documentation standpoint, the mechanism of scribing (in-room, remote, or AI-assisted) does not change the authentication framework. The physician must still review and sign.
What a well-structured virtual scribe workflow should include:
- Real-time documentation entered directly into the EHR during or immediately after the encounter, rather than after-hours reconstruction from memory or recordings.
- Physician review before or at the time of sign-off not days later.
- Clear identification (per many MACs) of who entered the note, where the MAC’s published guidance recommends it.
- A signed Business Associate Agreement (BAA) with the scribe service before any patient information is accessed, which is a HIPAA requirement independent of Medicare billing rules.
The physician’s signature at the end of that workflow is what transforms a documented encounter into an authenticated Medicare medical record.
Note: Chase Clinical Documentation’s
virtual medical scribe service is designed to support real-time EHR documentation with physician review and sign-off as the expected final step. Whether a given practice’s scribe implementation meets all applicable Medicare documentation requirements depends on the physician’s review process and compliance with their MAC’s guidance not the scribe service alone.
Amendments, Corrections, and Delayed Entries in Scribed Records
When a scribed note requires amendment after the fact, CMS guidance under the Medicare Program Integrity Manual (Chapter 3, Section 3.3.2.5) applies. Amendments, corrections, and delayed entries must:
- Clearly and permanently identify the change as an amendment, correction, or delayed entry.
- Clearly indicate the date and author of the change.
- Preserve all original content nothing may be deleted.
For electronic health records, the system must provide a reliable means to distinguish original content from modified content, including the date and authorship of each modification. This is a documentation integrity requirement that applies whether or not a scribe was involved in the original entry.
Conclusion:Accurate Documentation Starts With Clinician Review
Medicare scribe documentation requirements distinguish between preparing a medical record entry and authenticating it. CMS does not require a human or AI scribe to sign or date the entry merely because they documented it. The responsible physician or NPP must authenticate the record as required by applicable policy.
Signature attestations and signature logs can help resolve certain documentation issues, but they have specific limitations. Practices should confirm current CMS guidance, applicable MAC instructions, and any document-specific requirements before changing their workflows.

FAQ
Does a medical scribe need to sign a Medicare note?
No. Per CMS Change Request 10076, incorporated into the Medicare Program Integrity Manual (Section 3.3.2.4) and reaffirmed in the July 2025 MLN Fact Sheet, a scribe is not required to sign or date a medical record entry. Medicare reviewers are instructed not to deny claims solely because a scribe has not signed the note. The treating physician’s or NPP’s signature is the only authentication required.
Does a physician need to write a scribe attestation statement when using a medical scribe?
Not as a routine matter. An attestation statement is a remedy for a missing or illegible physician signature it is not a standard step in a properly documented scribe arrangement. The Wisconsin Physicians Service MAC has stated explicitly that in a scribe situation, no attestation is needed because the physician’s signature validates the record. Attestation is never accepted for orders.
What happens if a physician doesn’t sign a scribed note before it is submitted for billing?
A missing physician signature is a documentation deficiency that can result in claim denial. If a signature is absent from a medical record (but not an order), a signature attestation statement may be submitted retroactively. However, the attestation must be created by the treating physician who authored the entry, not by a colleague, partner, or the scribe.
Can an AI medical scribe be used for Medicare documentation?
The July 2025 CMS MLN Fact Sheet (MLN905364) explicitly addresses AI-assisted documentation, stating that if a provider uses a scribe “including artificial intelligence technology,” the provider must sign the entry to authenticate it. The same rule that applies to human scribes applies to AI-assisted tools: the physician or NPP must review and sign the note. CMS notes that it is unnecessary to document whether a human or AI transcribed the entry.
Who is responsible if a scribed note contains an error that affects billing?
The treating physician. When a physician signs a scribed note, they are affirming that the documentation accurately reflects the care provided. If the note contains inaccuracies that affect coding or medical necessity, the physician not the scribe is the author of record. This makes thorough physician review of every scribed note essential before sign-off.
Does my MAC require the scribe’s name to appear in the note?
CMS’s national policy under CR10076 does not require documentation of the scribe’s identity. However, several MACs including NGS, Novitas, and CGS recommend or require that the note indicate who entered it and on whose behalf. Practices should verify their specific MAC’s current published guidance and consider including scribe identification as a standard workflow element regardless, as it supports audit readiness.
