Diagnoses Procedures

ICD-10-CM (Clinical Modification)

All entities - providers and facilities for diagnoses in all settings: – Hospital inpatients – Hospital outpatients – Physicians offices – Emergency department – Home health – Long-term care – Rehabilitation facilities

ICD-10-PCS (Procedure Coding System)

Used by inpatient facilities ONLY • Includes outpatient facility services

rendered within the prior 72 hours of writing the inpatient order

• Very different than ICD-9-CM or CPT

CPT • Physician and outpatient/observation

facility services still utilize CPT • CPT does not change!!

Morbidity Uses Varying Implementation Throughout the World

The US is one of the last industrialized country to

adopt ICD-10 for clinical use

US Modifications – ICD-10-CM and PCS The Cooperating Parties

• CDC • Responsible for diagnoses

• CMS • Responsible for inpatient

procedures

• American Hospital Assn. • Responsible for interpreting

ICD-9 or ICD-10 (Coding Clinic)

• American HIM Assn. • Provides input from coding

community

ICD-10-CM/PCS Basics

• ICD-10-CM/PCS (and ICD-9-CM) are NOT clinical languages (like SNOMED) – ICD-9-CM and ICD-10-CM/PCS are useful for classifying

healthcare data for administrative purposes, including reimbursement claims, health statistics, and other uses where data aggregation is advantageous

• ICD-10-CM/PCS is based ONLY on provider documentation of clinical language, not on a patient’s clinical characteristics that are abstracted by a data analyst (e.g. like STS, NCDR, or ATS databases) – The provider must use the magic words that drive ICD-10-

CM/PCS code assignment based upon patient circumstances

10

ICD-10 Physician Revenue Cycle Impact

• Ancillary claim payment

– “Medical necessity” is currently based on an ICD-9-CM

• ICD-10 codes after October 1, 2014

– Payers typically release diagnosis codes supporting “medical necessity” through provider bulletins

• ICD-10 Payer Transition

– Starts with the CMS General Equivalence Mappings

– Additional modifications added according to their policies

– Results often published on the web or in their bulletins

• Hard to find

CMS National Coverage Determinations Home PT Monitoring

• Note that codes for secondary hypercoagulable states are not included.

“Family of Codes”

• “Family of codes” is the same as the ICD-10 three-character category. – Codes within a category are clinically related and provide

differences in capturing specific information on the type of condition.

– For instance, category H25 (Age-related cataract) contains a number of specific codes that capture information on the type of cataract as well as information on the eye involved.

• Examples include: H25.031 (Anterior subcapsular polar age-related cataract, right eye), which has six characters; H25.22 (Age-related cataract, morgagnian type, left eye), which has five characters; and H25.9 (Unspecified age-related cataract), which has four characters.

• One must report a valid code and not a category number. In many instances, the code will require more than 3 characters in order to be valid.

Medi-Cal ICD-10 Medical Necessity - Crosswalk

• Medi-Cal implementation of ICD-10 – Medi-Cal will be using a crosswalk solution in the legacy

California Medicaid Management Information System (CA-MMIS).

• Medi-Cal has mapped all ICD-10 codes to corresponding ICD-9 codes by starting with the General Equivalence Mappings (GEMs) provided by the Centers for Medicare & Medicaid Services (CMS) and modifying the mappings to align with existing Medi-Cal policy.

• Claims will be run against the crosswalk to determine the ICD-9 value to process through the system.

• Will an ICD-10 to ICD-9 crosswalk be published? – Medi-Cal will not publish the crosswalk. – However, the provider manuals will be updated with the

ICD-10 codes as appropriate.

Mapping Tool http://tinyurl.com/I9toI10crosswalk

Note how ICD-10-CM combined benign, malignant, and unspecified HTN into one code, I10 - HTN

Potential Problems with GEMS:

• A single ICD-9-CM code may now be represented by multiple ICD-10-CM codes • One to many

• Multiple ICD-9-CM codes may map to only one ICD-10 code • Many to one

• An ICD-10 code cannot be arbitrarily chosen from the GEM • A code may not represent the complexity of the illness (e.g. unspecified

code) – this could result in underpayments • A code may overstate the complexity of the illness – this could result in

audits and retrospective recovery of payments

ALWAYS VERIFY CODES IN THE ICD-10-CM BOOK PRIOR TO CLAIM SUBMISSION. DO NOT RELY ON ANY GEM TOOL ALONE

Surgeons must document BOTH the words “excisional”

and “debridement” to get the higher weighted DRGs

Wound Debridement ICD-10 Requirements

• If the word “debridement” is used, indicate – If it is excisional, non-excisional, or

the removal of a foreign body

– The instrument used • Scissors, scalpel, VersaJet, cautery, wire,

curette, irrigation, whirlpool, etc.

– The type of tissue excised • Skin, subcutaneous area, fascia, tendon,

muscle, bone, joint

– The anatomic location

46

Breast Surgery

• A 40 yo lady with a proportionally large left breast “mass” with calcifications on mammography presents for surgery. – An open biopsy indicates high-grade carcinoma

without clear margins, thus a complete mastectomy with a “sentinel node” biopsy was performed.

– Frozen section of the lymph node shows cancer, thus further axillary lymph node “dissection” was carried out.

47

Need for Nature and Anatomic Location of the Breast Tumor

• “Mass” is NOT a neoplasm or tumor – Physician must say

“tumor” or “neoplasm” – For inpatients, cannot

take information from the pathology reports

• Need the anatomic location of the tumor – Often, the location is on

an outpatient document that is not available to the hospital

48

Must code the

laterality or

else the claim

can be denied

Lymph Node Biopsy & “Dissection”

• No code in ICD-10 for “dissection”

• Was the lymph node biopsy diagnostic or therapeutic?

• Excision or resection? – All of the axillary lymph

nodes - resection? • Radical = resection

– Some of the axillary lymph nodes - excision?

• Sampling = excision

49

Axillary Lymph Nodes

50

Source: Public Domain

http://tinyurl.com/86ndkex

• Vary from 20-30 – Brachial (or "lateral") – Pectoral (or "anterior") – Subscapular (or

"posterior") – Central – Apical (or "medial" or

"subclavicular")

• Was it the provider’s intent to remove some or all of the lymph nodes? – ICD-10-CM coding rules

allow for the word “radical” to mean “all of the tissue” within a certain area

Amputations Need for Exact Operative Anatomy • Lower Body (include laterality)

– Hindquarter – Femoral Region – Knee Region – Upper/Lower Leg

• High (proximal) • Mid (mid portion) • Low (distal)

– Foot • Complete or partial

ray(s)/metatarsal(s)

– Toe • High (proximal phalanx) • Mid (PIP joint or middle phalanx) • Low (DIP joint or distal phalanx)

• Upper Body (include laterality) – Forequarter – Shoulder Region – Elbow Region – Upper/Lower Arm

Cleft Palate Repair

• Palate description

– Hard/Soft/Both

• Bilateral/Unilateral

• Complete/Incomplete

• With/without Cleft Lip Involvement

52

Omentum

• Any operation on the omentum requires that the physician document “greater omentum” or “lesser omentum” – ICD-10 does not

allow for “omentum” alone

53

Need for Exact Operative Anatomy

Coders need to know what biliary, GI,

circulatory, or other anatomy is partially

or completely removed, divided,

transferred, or inspected

ICD-10-PCS Lysis of Postoperative Adhesions

• 15-20% of open heart procedures commonly have adhesions – Almost 100% of

reoperations

• Requires a tedious lysis of adhesions, typically lasting around an hour, to reach the operative site

• Incidental injuries are common

• How do we handle this in ICD-10-PCS?

Coding Clinic (ICD-10), 1st Q, 2014, p.4 Lysis of Adhesions

• Carefully review the entire operative report (and not just the title) to determine the clinical significance of the adhesions and the complexity of the lysis of adhesions. – Coders should not code adhesions and lysis thereof, based solely on mention

of adhesions or lysis in an operative report. – Determination as to whether the adhesions and the lysis are significant

enough to code and report must be made by the surgeon.

• If obstruction is not present but a strong band prevents the surgeon from access to the organ (being removed), requiring lysis before the operation can proceed, then – Both the diagnosis of adhesions and the lysis procedure should be coded,

unless instructional notes in the Alphabetical Index, Tabular List, or guidelines preclude the separate coding.

• If adhesions exist without causing any symptoms in the patient or increasing the difficulty of performing the operative procedure. then – Coding a diagnosis of adhesions and the procedure of lysis of adhesions is

inappropriate.

Exact Body Part Being Released

57

While there are options for

unspecified parts of the

esophagus, stomach, small

intestine and large intestine…

ICD-10-PCS does have

specificity for which part of

these organs is being released

Other structures

can be freed as

well, including:

• Gallbladder

• Peritoneum

• Kidney

• Ureter

• Uterus

• Fallopian Tube

• Others

heart

DRG Consequences Lysis of Cardiac Adhesions w/CABG

CABG with no documentation of extensive lysis of adhesions • PDX - I25.110 - ASHD of

native coronary artery with unstable angina pectoris

• PProc – 021009W – for the CABG

MS-DRG 236 – Coronary Bypass w/o Cardiac Cath w/o MCC – 3.7777 NOTE: Also the resultant MS-DRG if only the pericardium is being released

CABG with documentation of extensive lysis of adhesions adherent to the heart

• PDX - I25.110 - Atherosclerotic heart disease of native coronary artery with unstable angina pectoris

• SDx – I31.0 – Chronic adhesive pericarditis

• PProc – 021009W for the CABG

• SProc – Adhesiolysis

– 4 code options - 02N(6,7,K,L)0ZZ

What are AHRQ PSIs?

• The Patient Safety Indicators (PSIs) are a set of indicators providing information on potential in hospital complications and adverse events following surgeries, procedures, and childbirth. – The PSIs were developed after a comprehensive

literature review, analysis of ICD-9-CM codes, review by a clinician panel, implementation of risk adjustment, and empirical analyses.

– Pediatric measures are also in place

Definition of a Complication in Coding Clinic

• It is important to note that not all conditions that occur during or following surgery are classified as complications. – First, there must be more than a routinely expected condition or

occurrence, and – There must be a cause-and-effect relationship between the care

provided and the condition, and • Differentiation between surgical/pharmaceutical care and diseases

– There is indication in the documentation that it is a complication.

• The coder cannot make the determination whether something that occurred during surgery is a complication or an expected outcome. – Only a physician can diagnose a condition, and the physician must

explicitly document whether the condition is a complication. – If it is not clearly documented, the coder should query the physician

for clarification.

Accidental Lacerations During Surgery Coding Clinic, 2nd Quarter 2007, pp. 11–12

• Question: During an procedure, the surgeon noted, “a small capsular injury of the spleen, which was hemostatic.” – This injury did not require repair.

• An esophagogastroduodenscopy (EGD) was then performed for evaluation of the distal esophagus since the mass had adhered at the gastroesophageal junction. – The EGD revealed a serosal injury to the stomach, which

was repaired with interrupted Lembert sutures. The surgeon did not include the intraoperative tears in the diagnostic statement. What are the appropriate code assignments?

82

Coding Clinic Answer

• Answer: Query the provider, and if the provider states the tear is not clinically significant, omit codes for both the diagnosis and procedure. – When a tear is documented in the operative report, such as a

small serosal tear of the stomach, the surgeon should be queried as to whether the small tear was an incidental occurrence inherent in the surgical procedure or whether the tear should be considered by the physician to be a complication of the procedure.

– If the provider documents that the seromuscular tear is a complication of the surgery, assign code 998.2, Accidental puncture or laceration during a procedure, as an additional diagnosis. This advice is consistent with that previously published in Coding Clinic, 3rd Quarter 1990, p. 18.

A Compliant Complications Query 2013 ACDIS-AHIMA Practice Brief

• Clinical scenario: During the removal of an abdominal mass, the surgeon documents, in the description of the operative procedure, a “serosal injury to the stomach was repaired with interrupted sutures.”

• Query: In the description of the operative procedure a serosal injury to the stomach was noted and repaired with interrupted sutures. Was this serosal injury and repair: – A complication of the procedure _____________ – Integral to the above procedure _____________ – Not clinically significant ____________________ – Other ___________ – Clinically Undetermined____________

Please document your response in the health record or below accompanied by clinical substantiation.

• Rationale: This is an example of a query necessary to determine the clinical significance of a condition resulting from a procedure. http://www.tinyurl.com/2013QueryPB

Bottom Line

• ICD-9-CM (and ICD-10) codes are crucial – Definitions are critical – Documentation infrastructure must support the

higher specificity

• Physicians are be incentivized to document and code completely in their offices – Especially important if they form Accountable Care

Organizations or participate in other entities emphasizing cost efficiency and outcomes.

• This lecture will orient the healthcare provider of what is needed now and what we can expect in the future
