Time

Question:

Our physician is coding by time; he thinks this is the best for him. Frequently with a new patient he will also do an injection. He documents his total time for the day but does not document the amount of time performing a minor procedure (billable). There is no documentation of the time spent preparing for or performing the minor procedure. May we still report a service based on time?

Answer:

CPT states “Time” may be selected based on the total amount of time spent on the date of encounter, excluding time spent for services that are defined by a separately reportable CPT code. This means that the total time must exclude the amount of time spent related to the minor procedure. If not documented, KZA recommends asking the physician to amend the note if possible (attesting that the time is accurate to the best of their knowledge) or reporting the service based on MDM.

Date of Service

Question:

We are in an academic setting. Our residents will see a patient, for example, at 11 pm on Tuesday.  Wednesday morning, our attending physician evaluates the patient, documents his/her findings, documents the required attestation, and enters an E&M into the EHR. The date of service is the date the encounter was created by the resident on Tuesday.   Do you bill the E&M with the Tuesday date of service or the Wednesday date when the attending physician saw the patient?

Answer:

The correct date of service is the actual date of service when the attending physician saw the patient. In this case, it will be Wednesday even if the attending physician links the note to the resident note from the previous date.

Diagnosis Coding Excludes 1 Codes

Question:

Our physicians list their diagnosis codes in the Assessment section of their notes. They link the diagnosis codes to the charges in our EHR. We receive a claims submission edit stating the two diagnosis codes may not be reported together. We review the rules and find the codes have an “Excludes 1” relationship. Our question is, should we remove the diagnosis code that is listed as the “Excludes 1” from the Assessment section of the note when correcting the claim based on the guidelines.

Answer:

No don’t do that but it is great news to hear you are reviewing your claims edit reports in a timely manner. The “Excludes 1” is an ICD-10-CM coding guideline or a coding rule. Think of this like an NCCI edit; when CMS has an edit between 2 CPT codes, we do not change the documentation in the operative note. Rather, we report the most comprehensive of the 2 CPT codes. The “Excludes 1” guideline is a similar concept—we do not change the documentation; rather, we report the most comprehensive diagnosis code.

E&M Coding Based on Time

Question:

Our physicians’ defaults to time for almost every office encounter. We are working with them on documentation and what work contributes to total time and what does not. They perform their own procedures such as skin lesion removal and biopsies in the office. They are counting the total time spent with the patient, including these activities and we do not believe that is correct. Can you help?

Answer:

Thank you for your inquiry. We will not address the default to time for almost every encounter other than to say medical necessity must be present for time spent. That said, the activities you identify are billable services represented by other CPT codes (aka are separately reported) and may not contribute to the total time in the billed Evaluation and Management (E/M). In other words, the procedure time must be deducted from the total time, assuming the E/M service is reportable.

Modifier Order on CMS Claim Form

Question:

We are submitting a hospital claim form with the modifier 25 and FS modifier. We are unsure which modifier to list first. What is your recommendation?

Answer:

Thanks for contacting KZA and remembering to use the FS modifier for shared services provided in the hospital. KZA recommends placing the modifier 25 first, as this is considered a reimbursement modifier followed by the FS modifier, which is an informational modifier.

Coding for a Laceration Repair

Question:

I repaired a 12 cm jagged laceration of the midabdomen by undermining 1cm to release the skin edges. Due to the length of the laceration and potential wound tension concerns, I closed the laceration in layers and retention sutures are used. What procedure code should I report?

Answer:

Good question. Because Undermining of tissue under skin, retention sutures constitute a complex repair. Since the defect is 12 cm you would report CPT code 13101 for the first first 2.6 to 7.5 cm with 13102 for each additional 5 cm or less.
