CPT Code 99242: Outpatient consultation billing guide

Key Takeaways

CPT Code 99242 covers office or other outpatient consultations requiring straightforward medical decision making (MDM) or a minimum of 20 minutes of total time.

Medicare Part B does not recognize CPT 99242 for payment – use office/outpatient E/M codes 99202-99215 instead when billing Medicare.

Three documentation requirements apply: a written referral request, the documented reason for the consultation, and a report sent back to the requesting provider.

Pabau’s claims management software streamlines consultation billing workflows, reducing claim errors and supporting compliant documentation across multi-specialty practices.

CPT Code 99242 is the code for an office or other outpatient consultation that requires straightforward medical decision making (MDM) or at least 20 minutes of total time on the date of service. It applies to new or established patients evaluated at another provider’s written or verbal request.

CPT Code 99242: Definition and clinical description

CPT Code 99242 is maintained by the American Medical Association (AMA) as part of the office or other outpatient consultation range (99242-99245). Under the 2023 AMA E/M guidelines, the code is supported by either straightforward MDM or a minimum of 20 minutes of total time spent on the date of service.

Medical decision making and time requirements

The 2023 AMA update removed the mandatory three-key-component framework (history, examination, MDM) for office E/M codes. For CPT Code 99242 specifically, you now select the code using either MDM complexity or total time – whichever you choose to document.

Straightforward MDM means a problem that is self-limited or minor, minimal data reviewed (ordering or reviewing a test, or reviewing external notes), and minimal risk – typically over-the-counter medications or no prescription drug management.

Time-based billing under the 2023 guidelines counts all time spent by the billing provider on the date of service, not just face-to-face encounter time. This includes reviewing records, ordering tests, and care coordination. Document the total time and what activities contributed to it.

A practical note on the old three-key-component framework: some commercial payers (notably Horizon Blue Cross Blue Shield of New Jersey) still reference expanded problem-focused history and expanded problem-focused examination in their reimbursement policies for 99242. Check individual payer contracts and policy pages before assuming 2023 AMA rules apply universally. Supporting medical documentation workflows with templated encounter notes helps practices satisfy both legacy and current requirements without duplicating effort.

Referral documentation: The three-requirement rule

Consultation codes carry a documentation burden that standard office E/M codes do not. Three conditions must be met and documented in the medical record before CPT 99242 can be billed:

• Request: A written or verbal request from another provider initiating the consultation. The requesting provider’s name and specialty must be documented.
• Reason: The clinical reason for the consultation must appear in the medical record, typically in the chart note or referral letter.
• Report: A written report must be sent back to the requesting provider. This report is what distinguishes a consultation from a standard office visit.

Missing any of these three elements is one of the most common audit triggers for 99242 claims. The Office of Inspector General (OIG) has flagged consultation code documentation as a recurring risk area. Using digital intake forms that include a referral source field and auto-generate consultation report templates reduces the chance a required element gets omitted.

Outpatient consultation codes 99242-99245: Selecting the right level

CPT Code 99242 sits at the lower end of the outpatient consultation range. Choosing incorrectly between adjacent codes is a common upcoding or downcoding risk.

CPT 99241 (the lowest level in the range) was deleted from the CPT code set in 2023 and is no longer billable. When reviewing superbills or charge masters, confirm 99241 has been removed and that 99242 is the lowest active outpatient consultation code available. Similar coaching CPT codes and other E/M references provide useful context for practitioners managing multi-service billing environments.

99242 vs 99243: The most common selection error

The boundary between 99242 and 99243 trips up billing staff regularly. Straightforward MDM requires that the problem be self-limited or minor, with minimal data review and minimal treatment risk. The moment a provider reviews an external physician’s notes, orders two or more tests, or manages a prescription drug, the MDM complexity tips toward low – and 99243 becomes the more appropriate code.

Document specifically what data was reviewed and what treatment risks were considered. Vague chart notes stating “reviewed prior records” without specifying what was reviewed give auditors insufficient basis to support either code level.

Medicare and payer rules

Medicare’s position on consultation codes is unambiguous. According to CMS MLN006764 (May 2026), Medicare does not recognize CPT codes 99242-99245 for Part B payment purposes. This has been policy since January 1, 2010. Billing Medicare with 99242 will result in a denial.

What to bill Medicare instead: Use the office or other outpatient E/M codes 99202-99215. For a new patient consultation that would have met 99242 criteria, 99202 (straightforward MDM, new patient) or 99203 (low complexity MDM, new patient) is typically the appropriate replacement. For an established patient, 99212-99213 covers similar complexity levels. Verify with your HIPAA compliance workflows and MAC guidance for any specialty-specific nuances.

Medicare does recognize telehealth consultation codes separately (HCPCS G-codes) in certain circumstances. Confirm with your Medicare Administrative Contractor (MAC) if telehealth consultation scenarios apply to your specialty and patient population.

Commercial and Medicaid payer variation

Commercial payers vary considerably. Many continue to recognize CPT 99242-99245 – including large regional Blue Cross Blue Shield plans, Aetna, and UnitedHealthcare in certain markets. CodingIntel (January 2026) notes the codes remain active CPT codes that may be recognized by one payer, several payers, or none at all, depending on geography.

Medicaid coverage is state-specific and cannot be generalized. Some state Medicaid programs recognize consultation codes; others follow Medicare’s lead and exclude them. North Carolina Medicaid, for example, includes 99242 in its visit limit code list with the three-key-component documentation framework still referenced. Always verify with the specific state Medicaid agency billing manual before submitting consultation codes.

Payment rates and coverage indicators vary by MAC locality, and commercial fee schedules are negotiated separately, so they will differ from Medicare rates. Check the AAPC Codify CPT lookup for additional crosswalk information and payer policy references.

Documentation requirements for CPT Code 99242

Insufficient documentation is the top reason consultation code claims are denied on audit. The chart note for a 99242 encounter must support the selected MDM level or the documented time – and it must separately satisfy the three-requirement referral rule. These are not the same thing: a well-documented MDM rationale does not substitute for a missing referral request.

Key elements to capture in the consultation report:

• Name and contact information of the requesting provider
• Reason for consultation as communicated by the requesting provider
• Nature of presenting problem and relevant clinical history
• Data reviewed: specify source (e.g., reviewed two prior lab results from external lab, reviewed imaging report from referring physician)
• Assessment and plan (including MDM rationale if billing by MDM)
• Start and stop times or total time, if billing by time
• Confirmation that a written report was sent to the requesting provider, with date

Maintaining patient record management systems that auto-populate referral source fields and generate consultation report outputs directly from the clinical note reduces the manual documentation burden substantially. This matters especially in high-volume specialist practices where consultation billing is the primary revenue driver.

Place of service and applicable settings

CPT Code 99242 applies in office or other outpatient settings. Place of Service (POS) code 11 (office) is the most common pairing. POS 22 (on-campus outpatient hospital) and POS 19 (off-campus outpatient hospital) may also apply depending on the consultation location. POS must match the actual site of service – mismatches between the claim POS and the facility billing for the same encounter are a known audit trigger flagged by the National Correct Coding Initiative (NCCI).

Inpatient consultation codes (99252-99255) apply when the patient is admitted. These are a separate code set and also not recognized by Medicare for Part B payment. Do not use 99242 for inpatient encounters. Understanding how practice management software can enforce POS coding rules at the point of charge entry reduces cross-setting coding errors before they become claims.

Reimbursement rates and fee schedule

Reimbursement for CPT Code 99242 varies by MAC locality, payer contract, and year. Medicare rates are set through the Medicare Physician Fee Schedule (MPFS) using relative value units (RVUs). Because Medicare does not pay 99242, the MPFS does not publish a payment rate for it – confirmed commercial payer rates are the relevant benchmark for this code.

For reference, the work RVU assigned to CPT 99242 in the AMA’s RVU database (used by commercial payers that follow the RBRVS methodology) is 1.08, down from 1.34 in 2022. Commercial payer contracts typically reimburse at a percentage of the Medicare conversion factor, so even for Medicare-excluded codes, the RVU framework drives most commercial rate negotiations.

Track 99242 payment rates and denial patterns over time within your practice management system. Consistent underpayment relative to contracted rates is recoverable lost revenue, but only systematic tracking will surface it.

Common denial reasons and audit risks

The OIG and commercial payer auditors consistently target consultation codes because they carry elevated documentation requirements that many practices do not fully satisfy. The most frequent denial and audit triggers for CPT 99242 are:

• Medicare submission: Billing 99242 to Medicare Part B is a guaranteed denial. Train billing staff to route Medicare consultations to the appropriate 99202-99215 code before claim submission.
• Missing referral documentation: No written record of the requesting provider’s referral. Verbal requests must be documented in the chart note.
• No report sent to requesting provider: The consultation report must be completed and transmitted. Documentation of the date and recipient protects against audit.
• MDM overcoding: Billing 99242 when the data reviewed or treatment risk actually meets low-complexity MDM (99243). Each data point reviewed must be individually documented.
• Wrong place of service: Using 99242 for inpatient or ASC encounters. POS must match the outpatient or office setting.
• Bundling errors: Billing 99242 on the same date as a procedure that includes consultation as part of its global package.

Proactive auditing using EHR integration tools that cross-reference MDM documentation against billed code levels catches most of these issues before claim submission. A pre-submission review workflow that checks for referral source documentation and consultation report status is particularly effective for high-volume consultation practices. Pairing this with automated billing workflows means the review happens systematically rather than relying on individual coder memory.

Conclusion

CPT Code 99242 remains a valid and commonly used code for straightforward outpatient consultations with commercial payers – but its documentation requirements are stricter than standard E/M codes, and its Medicare exclusion creates a significant denial risk when payer routing is not managed carefully.

Pabau’s claims management software helps specialist and multi-specialty practices automate the pre-submission checks that prevent the most common 99242 denials: missing referral documentation, MDM-level mismatches, and payer routing errors. Whether your practice operates in psychiatry or another specialty relying heavily on consultation billing, the right workflow infrastructure makes the difference between clean first-submission rates and recurring rework.
