QUESTION: Our pulmonologists are not comfortable documenting acute respiratory failure unless the patient is on a ventilator. Also, they rarely document chronic respiratory failure, even in chronic obstructive pulmonary disease (COPD) patients on continuous home oxygen. I’m trying to develop standard query forms for acute and chronic respiratory failure and am running into these obstacles. How do you recommend handling this problem?
QUESTION: We are a small anesthesia group and we are concerned about the specificity for ICD-10-CM. If we submit a claim with an unspecified code and the surgeon submits a claim with more specificity, will we still get paid?
QUESTION: A physician documents in an operative report debridement of a necrotic muscle (not due to an open wound). Must the physician also document how the muscle is removed to report ICD-9-CM procedure code 83.45 (other myectomy)? Is this considered excisional or nonexcisional debridement? What documentation is required to code the removal of a necrotic portion of a muscle?
QUESTION: Can you explain the difference between modifier -80 (assistant at surgery by another physician) and –AS (physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery)? Medicare requires us to use both modifiers for our physician assistants. We have been instructed to use -AS first and -80 second for all Medicare claims submissions. Is this correct?
Our coding experts answer your questions about unsuccessful foreign body removal, assigning modifier -52 for cancelled procedures, new HCPCS codes for April, reporting vaccine administration codes, new composite codes for 2012.
QUESTION: How will we be able to code for procedures such as Billroth procedures, Roux-en-Y anastomoses, and Whipple’s procedure when eponyms won’t be used in ICD-10-PCS?
QUESTION: I would like to know the correct codes to use when a patient comes into the ER after smoking synthetic marijuana and has symptoms of palpitations, seizure, or anxiety. Some physicians document ingestion, while others document abuse. What is the proper way to code considering we do not have a specific code for this new drug on the market?
QUESTION: For a healing traumatic finger amputation with concern but no diagnosis of infection at the amputation site (the physician prescribed Bactrim), is it correct to assign code V54.89 (other orthopedic aftercare) and ICD-9-CM code 886.x (traumatic amputation of finger)?
Our coding experts answer your questions about molecular pathology codes, HCPCS codes for drugs that aren’t separately payable under OPPS, deducting push time from infusions, CPT initial observation codes, and diabetes coding in ICD-10-CM.
QUESTION: We are having a discussion about how to code when the studies section of the history and physical (H&P) indicates that the chest x-ray showed atelectasis or that an electrocardiogram showed right bundle branch block with anterior fascicular block. Some of us believe that it’s okay to code the diagnosis (i.e., atelectasis) if the provider states that the testing “showed” the diagnosis, whereas others believe we cannot code the diagnosis as it is a lab/testing result, and the provider could just be reading the results onto his or her H&P dictation. I realize you cannot go to the testing result itself and code from it directly. However, I argue that it would be okay to code for it because the provider is using this information to make decisions about care, testing, and procedures, and he or she indicates the testing results in the H&P body. What are your thoughts?
QUESTION: Recently, reviewers have denied diagnostic code 584.9 (acute renal failure [ARF]) based on lab values. The diagnosis is well documented and treated by the attending physician, but reviewers are stating the lab values do not support the diagnosis of ARF. The lab values (creatinine/blood urea nitrogen) went from normal to abnormal, and we found no definitive standards for lab parameters to meet the definition of ARF. Following coding guidelines for reporting secondary diagnoses, the ARF was clinically evaluated, the patient received therapeutic and diagnostic procedures, and there was an extended length of stay/increased nursing care. As coders, we feel it is inappropriate to question the physician’s clinical judgment, and reporting the ARF as a secondary diagnosis is correct. Based on the documentation in the record, is it appropriate to code the ARF?
Q Addendum B of the APC updates for 2012 indicates the new molecular pathology codes have status indicator E (noncovered service, not paid under OPPS). Our laboratory director said we should report these new codes in addition to the codes that are payable. Can you explain why?
QUESTION: Can a patient have encephalopathy after surgery? For example, a patient becomes confused post-surgery and is transferred from the medical-surgical floor to the intensive care unit, where he or she receives high doses of pain medication via IV. However, the patient recovers well and the confusion disappears after the IV fluids and reduction in pain medication and oxygen. Would it be appropriate to query the physician regarding encephalopathy and its possible cause, or would this be a red flag for auditors? The situation did extend the patient’s length of stay by one day.
QUESTION: We have a question in regards to hydration that we are trying to figure out. Does the physician specifically have to state in his or her documentation that the IV is for hydration purposes or can a coder figure it out through critical thinking and using the process of hierarchal injection/infusion coding when reading the record? For example, X IV fluids are being used for an antibiotic and after the antibiotic, the IV fluids continue at 125/hr for hydration. Does the physician need to document "for hydration"? Our physicians do not want to write that. Do you have any good advice on this?
QUESTION: We are a nondialysis facility, so when a patient is in observation for some other reason and must undergo hemodialysis, we report code G0257 (unscheduled or emergency dialysis treatments for an ESRD [end stage renal disease] patient in a hospital outpatient department that is not certified as an ESRD facility). But how should we code peritoneal dialysis when a patient is in observation or inpatient for other problems? I have received three different codes from different coders. I cannot really find any information on this anywhere.
Q We're struggling with nursing documentation of stop times for IV infusions (e.g., piggybacks and hydration). The nurses also inconsistently document a patient's return to the unit from diagnostics. We know that CMS now allows us to use average times for common services, and we're interested in considering this approach at my organization. Can you share additional specifics?
QUESTION: A physician admits a 30-year-old male with lower abdominal pain. A CT scan showed consistency with perforated appendicitis. However, the patient had an appendectomy 10 months prior. The physician documents "appendiceal stump syndrome." How should I code this case?
