Two things landed in your inbox the same week. A payer requested documentation for eleven claims billed with CPT 99497 over the past quarter, asking specifically for start and stop times. And the adult son of a patient who died in February asked for a copy of his mother's POLST form, which your practice scanned into her chart in 2023. Both requests trace back to the same fifteen-minute conversation in an exam room — and the advanced care planning CPT codes that conversation generated.

This guide is for the administrator, biller, or privacy officer who owns both problems. It covers how practices document and determine code selection for advance care planning, then makes explicit what those records mean for right-of-access requests, personal representative verification, and your business associate inventory. It is not clinical guidance and it does not tell you which code fits a given encounter.

What the Advanced Care Planning CPT Codes Describe

CPT defines two time-based codes for this service. The correct term of art is advance care planning, though most people search for "advanced care planning cpt" — the codes are the same either way.

  • 99497 — advance care planning including the explanation and discussion of advance directives such as standard forms, with completion of such forms when performed, by the physician or other qualified health care professional; first 30 minutes, face-to-face with the patient, family member(s), and/or surrogate.
  • 99498 — each additional 30 minutes.

Three operational facts your billing staff should have memorized. First, no advance directive has to be completed for the service to be reportable — the discussion itself is the service. Second, the patient's participation must be voluntary, and a patient who declines the conversation means no service. Third, these are counseling codes with no procedure attached, so the entire defense of the claim rests on the note.

Who can bill it

Under Medicare, physicians and other qualified health care professionals whose scope permits the service — nurse practitioners, physician assistants, clinical nurse specialists — report these codes. Social workers, chaplains, and care coordinators frequently do the substantive work in real practices, but their time does not convert into a billable unit under these codes on its own. If your care team model relies on non-billing staff, decide in advance how that is documented so nobody reconstructs it later under audit pressure.

The 16-Minute Threshold and the Time Log Your Auditor Will Read

CMS guidance has long treated 99497 as reportable when more than half of the 30-minute increment is spent — at least 16 minutes of face-to-face time. Anything under that is not a shorter version of the code; it is not the code at all.

That single number drives your entire documentation template. Practices that survive time-based audits capture, at minimum:

  1. Total minutes spent, ideally with start and stop times rather than a rounded total.
  2. Who was physically present — patient, family member, appointed surrogate — and their relationship.
  3. That the patient (or surrogate) consented to the discussion and that it was voluntary.
  4. What was discussed: which directive forms, which decisions, which questions the patient raised.
  5. Whether forms were completed, and where the completed form was filed.
  6. The billing practitioner's own attestation and signature, not a scribe's summary alone.

"Advance care planning discussed, 30 minutes" is not documentation. It is a template default, and reviewers recognize it instantly. Time-based, self-attested services with no objective procedure attached are exactly the claim profile that attracts payer review, so build the template to be boring and specific.

Frequency is not capped, but repeat billing needs a reason on the page — a change in health status, a new diagnosis, a revised surrogate designation, a patient who asked to revisit an earlier decision. Your internal rule should be that the second and subsequent claims for the same patient in a year state why the conversation happened again.

Billing Advanced Care Planning CPT Alongside the Annual Wellness Visit

This is where most practices generate patient complaints, and complaints are a compliance problem even when the coding is clean.

When advance care planning is furnished as an optional element of the Medicare Annual Wellness Visit on the same date, and the claim carries modifier 33, Medicare waives the deductible and coinsurance. When the service is furnished on any other date, or without the AWV linkage, the patient's cost-sharing applies.

Your front desk needs to know which of those two situations it is before the patient leaves. A retiree who thought a wellness visit was free and gets a coinsurance bill six weeks later will call, and the call will land on your desk. Give schedulers a one-line script and give billers a pre-submission check: if 99497 is on the claim without an AWV code on the same date, confirm the patient was told cost-sharing applies.

Two other billing mechanics worth writing into your policy. CPT instructions bar reporting these codes on the same date as critical care and certain neonatal and pediatric intensive care codes — confirm against current CPT instructions before you build an edit. And only one practitioner should report the service per session; if a hospitalist and a primary care physician both touch the conversation, decide who bills. For current national payment amounts and locality adjustments, pull them yourself from the CMS Physician Fee Schedule Look-Up Tool rather than relying on a vendor's cached figure.

Telehealth eligibility for these codes has moved repeatedly with congressional extensions and lapses. Do not assume last year's answer holds. Verify status against current CMS guidance before you let the schedulers book these as virtual visits.

Where the Documentation Lives — and Why It Becomes a Records Problem

An advance care planning encounter produces three distinct artifacts, and they behave differently.

The progress note with the time log is a treatment and billing record. The completed directive — living will, healthcare power of attorney, POLST or MOLST, depending on your state — is a legal instrument that happens to be scanned into your chart. The scheduling and outreach trail that got the patient into the room may live in a patient engagement tool outside the chart entirely.

All three sit in your designated record set. That means all three are reachable by a right-of-access request.

The 30-day clock on a directive request

A patient or personal representative who asks for a copy of the advance directive in your chart triggers the same access timeline as any other request: 30 calendar days, with one 30-day extension available if you notify the requester in writing with a reason. HHS's right of access guidance is explicit that you cannot condition release on the patient explaining why they want it, and you cannot charge more than a reasonable, cost-based fee.

The practical failure is routing. Directives are often scanned to a separate document folder or a shared drive, and the release-of-information clerk searching the chart's clinical tabs reports "no records found." Fix this by mapping, in writing, every location a directive can be stored — including any external registry your clinicians upload to — and putting that map in the ROI desk procedure.

Verifying the person holding the healthcare proxy

Advance care planning conversations frequently include a surrogate, and that surrogate may later present as the patient's personal representative under HIPAA. Somebody named in a healthcare power of attorney generally has the same access rights the patient has, to the extent of their authority. Somebody who merely sat in the room does not.

Your staff needs a documented verification step: what document establishes the authority, who reviewed it, when, and whether the authority is limited in scope. "She was at the appointment with him" is not verification. Note also that a directive naming an agent is not the same as a durable power of attorney for finances, and staff who cannot tell them apart will over-disclose.

After the patient dies

PHI stays protected for 50 years following death. The family member who asks for a copy of the directive after a death is either acting as the executor or personal representative of the estate — in which case they generally get access — or they are a family member who was involved in care before death, in which case a narrower permitted disclosure applies and only for information relevant to that involvement. Have that distinction written down before the phone rings, because it rings on the worst possible day.

The Vendor List This Service Creates

Run the workflow end to end and count the third parties handling PHI:

  • The e-signature platform capturing the directive signature.
  • The document scanning or indexing service digitizing paper forms.
  • Any state or regional advance directive registry you upload to.
  • The transcription service or AI scribe capturing the conversation — including, in many products, an audio recording of the patient discussing end-of-life wishes.
  • The telehealth platform, if any part of the conversation happened remotely.
  • The patient outreach tool that texted the appointment reminder describing the visit purpose.
  • The billing company or clearinghouse submitting the claim with the diagnosis attached.

Every one of those is a business associate. The scribe vendor deserves particular attention: an audio file of a patient naming a surrogate and describing resuscitation preferences is among the most sensitive recordings your practice will ever hold, and you need to know from the contract how long the vendor retains it, whether it is used for model training, and what happens to it at termination.

If you find a vendor on that list without a current, signed agreement — which is the usual outcome of this exercise — you can produce a signature-ready Business Associate Agreement through a six-step wizard with PDF and DOCX export, as a one-time purchase rather than another subscription. Close the gap the same week you find it and log the date you sent it.

A Quarterly Self-Review You Can Run in 90 Minutes

Pull ten claims carrying advance care planning codes from the prior quarter and check each against a fixed list:

  1. Does the note state total time, and does it clear the 16-minute threshold for 99497?
  2. Is the voluntary nature of the discussion documented?
  3. Is the billing practitioner's signature present, distinct from any scribe attribution?
  4. If 99498 was added, is the additional increment separately supported?
  5. If modifier 33 was used, is there an AWV on the same date?
  6. If no AWV, is there evidence the patient was informed about cost-sharing?
  7. Where is the completed directive filed, and can the ROI clerk find it in under two minutes?
  8. If a surrogate was present, is the relationship documented and the authority verified?

Log the results, log the corrections, and log who did the review. That log is the difference between "we have a process" and "we can show you our process," and the second one is what matters when a payer or an investigator asks. If your broader documentation set — risk analysis, policies, workforce training records — is thinner than it should be, tools that automate HIPAA risk analysis and the supporting policy set will get you to a defensible baseline faster than building it from scratch in a word processor. HHS does not certify or endorse any product, so treat any "certification" language you encounter accordingly.

Start With the Vendor Inventory

Advance care planning is one of the few services where the billing artifact, the legal artifact, and the most sensitive conversation in medicine all land in the same chart. Get the time documentation right so the claims hold. Get the storage map right so access requests get answered in 30 days. And get the paper right with every vendor touching that record — generate the missing Business Associate Agreements before the next scanning contract renews.
