CPT Code 99254 Explained: Inpatient Consultation Billing Guidelines 2026
Inpatient consultation coding is one of the most technically demanding areas of evaluation and management billing. CPT code 99254 sits at the moderate-complexity level of the inpatient consultation range requiring either a specific standard of medical decision making or a minimum time threshold and comes with documentation requirements that are significantly more detailed than routine hospital visit coding. Getting this code right matters financially. Miscoded consultations result in claim denials, downcoding, or in the case of Medicare, automatic non-payment regardless of documentation quality. Overcoded consultations create compliance exposure. And missing the payer-specific rules around consultation codes costs practices billable revenue on every affected claim. This guide covers everything billing professionals and providers need to know about CPT code 99254 from the clinical criteria and documentation requirements to the Medicare rules that many practices still mishandle fifteen years after they changed. What Is CPT Code 99254? CPT code 99254 is an inpatient or observation consultation code used to report evaluation and management services when a physician or qualified healthcare professional is requested by another provider to evaluate a patient in a hospital or observation setting and provide expert opinion or recommendations. Per the current AMA CPT guidelines, 99254 applies when the consultation involves either: A moderate level of medical decision making (MDM), OR A minimum of 60 minutes of total provider time on the date of the encounter The 60-minute threshold is a minimum, not a typical time total time includes all physician work on the encounter date: reviewing records, patient evaluation, documentation, and care coordination. Source: AAPC CPT Code 99254 description; AMA CPT Guidelines 2025 The Three Core Requirements of a Legitimate Consultation This is where many consultation billing errors originate. CPT consultation codes including 99254 require three specific elements that must all be present and documented for a claim to be valid. These are often called the ‘three R’s’ of consultation billing: Requirement Element Documentation Standard 1. Request Another provider requests the opinion The requesting provider, their specialty, and the reason for the consultation must be documented. A verbal request is not sufficient it must be documented in the medical record. 2. Render Consultant evaluates the patient The consulting provider must personally evaluate the patient and document history, examination, and clinical findings relevant to the consultation question. 3. Report Findings communicated back A written report with clinical findings and recommendations must be communicated back to the requesting provider. This communication must be documented in the record. If any one of these three elements is missing from the documentation, the claim cannot be billed as a consultation. It must be reported as a standard inpatient E/M visit instead. Billing 99254 without all three elements documented is a compliance violation. Moderate Medical Decision Making (MDM) What Qualifies for 99254 When billing 99254 based on MDM rather than time, the encounter must meet the AMA’s criteria for moderate complexity medical decision making. MDM is evaluated across three components: MDM Component Moderate Complexity Criteria Examples Problems addressed One or more chronic conditions with exacerbation OR new problem requiring additional workup Acute-on-chronic heart failure, new diagnosis requiring specialist opinion, complex multi-system presentation Data reviewed and analyzed Review of prior external notes AND ordering or reviewing tests AND independent interpretation Reviewing prior hospital records, ordering labs or imaging, interpreting results independently from the ordering physician Risk of complications Prescription drug management OR diagnosis or treatment requiring intensive monitoring Adjusting anticoagulation dosing, managing immunosuppressants, recommending procedures with moderate procedural risk For MDM to qualify as moderate, the encounter must meet at least two of the three component levels shown above. If only one component meets the moderate threshold, the MDM is lower and a lower-level code should be used instead. Time-Based Billing for CPT 99254 As an alternative to MDM-based coding, 99254 may be reported based on total provider time on the date of the encounter. The minimum time threshold is 60 minutes. What counts as billable time: Reviewing patient records including records from other providers or prior admissions Patient evaluation direct face-to-face time examining the patient Documentation writing the consultation note Care coordination communicating with other treating providers, nursing staff, or family Interpreting test results laboratory, imaging, or other diagnostic results What does NOT count as billable time: Time spent by other clinical staff (nurses, residents under supervision, mid-levels) Time on other dates only time on the specific date of the consultation Administrative time unrelated to the clinical encounter When billing based on time, the total time must be explicitly documented in the note. Stating the level of MDM is not sufficient for time-based billing. The note must record the actual total minutes spent on the consultation date and identify the activities that comprised that time. Medicare and CPT 99254 The Rule That Many Practices Still Get Wrong This is the most consequential compliance issue in inpatient consultation billing, and it is worth stating with complete clarity: Medicare has NOT reimbursed consultation codes including CPT 99254 since January 1, 2010. Submitting 99254 to Medicare will result in automatic non-payment. This is not a guideline, not a preference, and not a ‘typically’ it is an absolute policy that has been in place for over 15 years. The background: CMS formally eliminated all consultation codes (99241-99245 and 99251-99255) from Medicare Part B payment effective January 1, 2010, through Transmittal 1875, Change Request 6740. The AMA retained consultation codes in the CPT codebook because non-Medicare commercial payers may still accept them but for Medicare, they are non-covered services.
