Agent reasoning
I need to verify the patient's active coverage and benefits status with UNITED HEALTHCARE OXFORD FREEDOM NETWORK before proceeding with claim setup. This is the first critical step in the revenue cycle to ensure the patient is eligible on the date of service and to confirm copay, deductible, and coinsurance details.

Agent reasoning
I have verified eligibility, but I need to thoroughly review the clinical documentation to identify all billable services, assess the level of E/M service, and determine the correct diagnoses from SNOMED. The visit is marked as a new patient urgent care visit with a chief complaint of ankle pain and physical exam findings. I will read the full progress note to evaluate MDM, time, and any procedures or orders that may generate billable charges.

I need to review the full clinical documentation to ensure I capture all relevant details for coding, including the HPI, exam findings, and any procedures or services documented. Specifically, I need to confirm the nature of the ankle injury, laterality, and whether any imaging or other services were performed or ordered.

Agent reasoning
I have verified patient eligibility and coverage is active. The next critical step is to review the clinical documentation in detail, particularly the SNOMED diagnosis and clinical note, to ensure I accurately translate the documented condition into the correct ICD-10-CM code with proper laterality and acuity. The primary SNOMED code 44465007 is documented as the reason for visit 'pain, ankle' with a history of a twist one week ago and current swelling and pain on inversion at the lateral malleolus — this suggests a sprain, but I must confirm the specific ICD-10-CM code for a right ankle sprain.

I need to review the full clinical documentation to assess the level of medical decision making (MDM) and determine if an Evaluation and Management (E/M) service is separately billable or included in the urgent care global rate. The visit type is 'UC - NEW' and the facility is an urgent care (POS 20), so I must confirm whether the payer bundles the E/M into a global HCPCS code for urgent care services. I will read the full progress note to evaluate the documented history, exam, and plan for MDM components.

I have reviewed the patient's clinical note and confirmed that the primary diagnosis is an ankle sprain, specifically involving the right ankle, with documentation of a twisted injury one week ago and current pain and swelling. The next step is to verify the correct ICD-10-CM code for this condition with proper laterality and encounter type. Based on the documentation, this is a subsequent encounter for an initial sprain (since it's one week out and still being actively managed), so I will confirm the accuracy of the previously looked-up code S93.401A for 'Unspecified sprain of right ankle, initial encounter' to ensure it matches the clinical picture.

The SNOMED code 44465007 corresponds to an ankle sprain, and based on the clinical documentation (right ankle swelling, pain on inversion, history of twisting injury), the correct laterality is right, and the encounter is initial. The lookup confirmed ICD-10-CM code S93.401A ('Sprain of unspecified ligament of right ankle, initial encounter') is valid and specific to the documented condition. Since the patient is a new patient at an urgent care with a new problem and requires MDM related to a musculoskeletal injury, the diagnoses are now ready to be formally set on the claim. No additional SNOMED conditions are documented, so one primary diagnosis is sufficient.

I need to determine the correct E/M code level by evaluating the medical decision making (MDM) based on the documented problems, data reviewed, and risk. The patient is a new patient with an acute ankle injury (SNOMED 44465007), which requires evaluation and management. Although no labs or imaging were ordered, the condition involves an acute musculoskeletal issue with pain and swelling, which typically constitutes a problem of low to moderate severity. However, no diagnostic tests were ordered or reviewed, and no treatment was documented beyond follow-up instructions, so I need to confirm if MDM rises to moderate or remains at low complexity.

The claim was denied with CARC CO-150/M25, indicating the E/M level (99202) is not supported by documentation and suggesting unbilled services may exist. I need to re-evaluate whether this visit should be coded as a comprehensive urgent care visit (HCPCS G0380/G0378) rather than a standard E/M code, as per UnitedHealthcare’s urgent care billing rules. First, I will look up the payer's policy to confirm their guidelines for urgent care visits and whether a global code is required instead of 99202.

The claim was denied with CARC CO-150 and RARC M25, indicating the E/M level billed (99202) is not supported by documentation and/or there are unbilled services. I need to verify the exact meaning of these denial codes to understand payer expectations and determine whether the issue is under-coding (missed charges) or over-coding (unsupported level). This will guide whether I need to increase or decrease the E/M level or add additional service lines.

The denial CARC CO-150/M25 indicates the E/M level is not supported by documentation or time, and suggests unbilled services may exist. I need to carefully reassess the E/M level by reviewing all documented elements including history, exam, medical decision making, and time, and verify if any additional services were performed but not billed. I will start by reading the clinical note in full to evaluate the level of service and identify any missed charges.

The claim was denied for insufficient documentation to support the E/M level (CO-150/M25), and the payer specifically noted that services may have been unbilled. I need to re-review the clinical note and visit metadata to determine if additional billable services were documented but not captured, and reassess the correct E/M level based on total time or MDM. Since the original submission used 99202, which is a low-level new patient visit, but the patient presented with an acute injury (ankle pain/swelling) that required assessment and potential imaging, I must verify whether any orders (e.g., X-ray) were documented and if so, ensure they are coded appropriately.

The denial CARC CO-150 with RARC M25 indicates the E/M level billed (99202) is not supported by documentation and suggests unbilled services may exist. I need to re-evaluate the level of service by assessing total visit time and MDM documented. The visit note describes evaluation of a new patient with an acute injury, including exam of multiple body systems, and plans for follow-up, suggesting at least moderate MDM. I will now review the progress note in detail to extract all clinical activities and determine correct E/M level based on time and medical decision making.

The denial CARC CO-150 with RARC M25 indicates that the E/M level billed (99202) is not supported by documentation and suggests that services may have been unbilled. I need to carefully re-examine the clinical note to determine if additional services were performed but not captured (e.g., imaging, injection, or medical decision making) that could support a higher-level visit or an unbundled service. Specifically, I will review the 'clinical_note_(free_text)' section for any mention of ordered tests, procedures, or complexity of the problem that could impact E/M level or reveal missed charges.

The claim was denied with CARC CO-150/M25, indicating the E/M level billed (99202) is not supported by documentation and/or services were missed. I need to verify the official meaning of CO-150 to understand payer expectations. Although previously attempted, confirming via authoritative source is critical before altering coding, especially since the denial cites both undercoding (unbilled services) and level lack of support.

The denial CARC CO-150 with RARC M25 indicates the E/M level is not supported by documentation or that services were missed in billing. The current claim bills 99202, a low-level new patient visit, but the note mentions an ankle injury with swelling and pain, which may support a higher level of service based on MDM or time. I need to re-examine the clinical note and visit details to determine if a higher E/M level is justified or if additional billable services (e.g., X-ray) were performed but not coded.

The denial CARC CO-150 with RARC M25 indicates the E/M level billed (99202) is not supported by documentation and suggests unbilled services may exist. I need to revisit the clinical note to assess whether an urgent care global service was performed, which would require a different HCPCS code (e.g., G0463) instead of a standalone E/M code, as per payer policy for urgent care settings. This could explain both the level-of-service mismatch and the hint that services were underbilled.
